Travel Health Guide: Ireland

Ireland is a low-risk destination for US travelers in the conventional sense: no malaria, no yellow fever, no dengue, no rabies on the mainland, and tap water that meets EU and WHO drinking standards in every city and most rural areas. The travel-medicine work for a US trip to Ireland is concentrated in four genuinely actionable risks: confirmed measles transmission across Europe with Irish MMR uptake at 87.6 percent (below the 95 percent threshold needed to block outbreaks), Lyme disease from Ixodes ricinus ticks with up to 400 cases a year and roughly 5 percent of ticks carrying Borrelia, a paid healthcare system for non-EEA visitors where a single emergency-department visit costs €100 to €506 and an inpatient admission runs €800 to €1,500 per night, and a controlled-drug import framework where Adderall and other US stimulants need a doctor's letter and the original prescription to clear customs. The right pre-trip plan covers MMR status, an EPA-registered tick repellent, a travel insurance policy that includes medical evacuation, and the right paperwork for any prescription you carry. Every traveler should also build a basic plan for Ireland's changeable weather, since the country recorded its warmest summer on record in 2025 and several long-standing mountain-rescue patterns are tied to weather rather than terrain.

Quick facts

• Region: Northwestern Europe (island of Ireland, comprising the Republic of Ireland and Northern Ireland)
• CDC travel notice level: Level 1 (standard precautions)
• US State Department advisory: Level 1 (exercise normal precautions)
• Annual US visitors: roughly 1.5 to 1.7 million per year; US is the second-largest inbound market behind the UK (Fáilte Ireland, CSO)
• Key health risks: measles exposure, Lyme disease from tick bites, summer heat in unconditioned buildings, hiking and mountain weather, paid healthcare for tourists
• Recommended vaccines: MMR (two documented doses), Tdap, polio booster for adults, hepatitis A, hepatitis B for some itineraries, annual influenza, age-appropriate COVID-19
• Recommended medications: scopolamine for ferry crossings or rough Atlantic boat trips, azithromycin standby for traveler's diarrhea on rural well-water itineraries, post-tick-bite doxycycline access if you are spending time in tick habitat
• Travel insurance: strongly recommended. Medicare does not cover care outside the US, and HSE bills non-EEA visitors at full rates
• Currency: euro (€) in the Republic; pound sterling (£) in Northern Ireland
• Time zone: Irish Standard Time (UTC+1 in summer, UTC in winter)
• Emergency numbers: 999 or 112 anywhere on the island

Overview: what actually matters for a US trip to Ireland

Ireland sits in an unusual middle space among Wandr destination guides. There are no exotic pathogens to worry about, but there are several modern, evidence-backed risks that catch US travelers off guard precisely because the trip feels familiar. The most common mistake we see is treating Ireland as a no-prep destination and then being surprised by a Lyme rash three weeks after a Wicklow Way walk, by a €1,200 ambulance and A&E bill after a fall on a Cliffs of Moher headland, or by a customs delay over an Adderall bottle without a clinician letter.

The four risk vectors that drive almost every traveler health issue on Ireland trips are infectious (measles and Lyme), environmental (weather and heat), financial (HSE charges plus no Medicare coverage), and pharmaceutical (controlled-drug import rules). Each is addressable with a small amount of pre-trip work, and the rest of this guide walks through how to do that work efficiently.

Vaccines for Ireland

The CDC does not require any vaccine for entry to Ireland, and Ireland does not check yellow fever certificates because there is no transmission risk. The recommendations below cover what most US adults and families should verify or update before flying.

MMR (measles, mumps, rubella): the most important pre-trip vaccine

Measles is the single vaccine-preventable risk that is most likely to affect a US traveler to Ireland in 2026. The HSE has reported sporadic confirmed measles cases in 2025 and 2026, and Ireland's MMR uptake among children aged 24 months is 87.6 percent (HSE HPSC Q2 2025 data), below the 95 percent uptake the WHO considers protective against outbreaks. Several other European countries with major air links to Ireland are running larger active outbreaks. The HSE has issued public-health warnings ahead of school holidays and Easter travel that any unvaccinated person traveling internationally is at risk.

CDC recommendations for measles and international travel:

• All US travelers aged 12 months or older should have two documented MMR doses, separated by at least 28 days, completed before departure
• Infants aged 6 to 11 months traveling internationally should receive one early dose of MMR at least two weeks before travel; this early dose does not count toward the routine series and the child still needs the standard 12 to 15 month and 4 to 6 year doses
• Adults born in 1957 or later without documentation of immunity should receive at least one MMR dose
• Adults at higher exposure risk (healthcare workers, international travelers, students) should have two documented doses
• Two doses of MMR are roughly 97 percent effective at preventing measles; one dose is roughly 93 to 95 percent effective

A single missed MMR catch-up dose is the largest preventable risk on a typical Ireland trip. Most adults already have two doses, but if you cannot find documentation and you were born after 1956, getting a booster is reasonable and harmless.

Routine and travel vaccines

CDC's standard recommendations for Ireland cover what most US adults need beyond MMR.

• Tdap (tetanus, diphtheria, pertussis): every 10 years for adults; one dose in every pregnancy
• Polio: one-time adult booster recommended for travelers given ongoing European poliovirus surveillance signals
• Annual influenza: especially relevant for fall and winter trips
• COVID-19: age-appropriate dose per current CDC guidance
• Hepatitis A: recommended for most travelers; widely available and routinely combined with hepatitis B in the Twinrix series
• Hepatitis B: recommended for travelers with healthcare exposure, tattoos or piercings planned abroad, or new sexual partners
• Varicella (chickenpox): verify two doses or documented immunity, especially in adults born after 1980

Travel vaccines such as typhoid, Japanese encephalitis, yellow fever, and rabies are not recommended for Ireland.

How vaccines work through Wandr

For vaccines like MMR, hepatitis A, hepatitis B, Tdap, polio, and seasonal influenza, Wandr books your appointment at a partner pharmacy and the pharmacist administers your vaccines on-site under standing orders. You pick a Walgreens location and a time, Wandr handles the booking, and you skip the separate travel-clinic visit. There is no separate physician prescription for travel vaccines in the United States.

Lyme disease and Irish ticks: what to actually do

Lyme disease is the second public-health priority for an Ireland trip after MMR. The HSE estimates up to 400 cases of Lyme disease per year in Ireland, with roughly 10 to 20 cases of neuroborreliosis (the most severe central-nervous-system form) reported to HPSC each year. Roughly 5 percent of ticks in Ireland carry Borrelia burgdorferi, the bacterium that causes Lyme disease, per Irish surveillance data. The principal vector is Ixodes ricinus, the same European castor-bean tick responsible for most British and continental Lyme cases.

Where ticks live in Ireland

Ixodes ricinus is established across Ireland in any habitat with grass, leaf litter, deer, and rodents to feed on. The highest-density areas reported by HPSC and the Irish Times include:

• The Wicklow Mountains and Wicklow Way
• Killarney National Park and the Kerry uplands
• Connemara and Connacht moorland
• The Burren in County Clare
• Donegal and the northwest highlands
• The Mourne Mountains and Antrim Coast in Northern Ireland
• Forest parks throughout the country (Coillte and National Parks and Wildlife Service sites)

You can pick up a tick in your hotel garden in Dublin too, but the bulk of bites happen on walks through long grass, heather, bracken, or woodland leaf litter.

When ticks are active

Tick activity in Ireland traditionally peaks April through June, with a secondary autumn peak in September and October. Climate change has lengthened this season. Irish researchers reported in 2022 that the tick season is starting earlier and ending later, and that warmer winters are allowing some adult ticks to remain active year-round in the south and east. Plan as if April through October is peak season and assume any walk in heather or long grass is exposure.

The full tick-protection protocol

The CDC-recommended tick protocol cuts bite risk by roughly 80 to 95 percent in field studies.

1. Treat clothing with permethrin. Permethrin is an EPA-registered insecticide applied to fabric (not skin). One treatment lasts roughly six washes. Treat trousers, socks, gaiters, and hat the day before you fly; let dry fully before packing.
2. Apply an EPA-registered skin repellent. DEET at 20 to 30 percent or picaridin at 20 percent applied to exposed skin (ankles, neck, wrists). Reapply per label.
3. Tuck trousers into socks when walking in heather, bracken, or long grass. The look is dorky and the protection is real.
4. Stay on the center of marked trails where the cover is shorter and dryer.
5. Do a full body tick check the same evening, paying extra attention to behind the knees, groin, armpits, scalp, hairline, and behind the ears.
6. Shower within two hours of coming indoors if practical; this washes off any unattached ticks.
7. If you find an attached tick, remove it with fine-tipped tweezers grasped close to the skin, pull straight up with steady pressure, clean the bite, and note the date.
8. Watch the bite site for 30 days. The classic erythema migrans rash (a slowly expanding bullseye or solid red patch over 5 cm) is the most reliable early sign of Lyme; flu-like symptoms (fever, headache, joint pain, fatigue) within four weeks of a known bite also warrant evaluation.

For more on chemistry and concentrations across the major repellents, see our companion guide Insect Repellent for Travelers: DEET vs Picaridin vs Permethrin.

Treatment

First-line treatment for early Lyme disease in adults is doxycycline 100 mg orally twice daily for 10 to 14 days, per the Infectious Diseases Society of America 2020 guidelines. Some travelers ask about single-dose post-exposure prophylaxis. The IDSA endorses a one-time 200 mg doxycycline dose within 72 hours of a confirmed Ixodes scapularis bite in high-prevalence US regions, but Irish surveillance does not yet support routine post-exposure prophylaxis after Irish bites. Talk to your clinician.

Summer heat, wind, and rain: planning for changeable weather

Met Éireann confirmed that summer 2025 was Ireland's warmest on record, with a mean temperature of 16.19 °C, narrowly above the previous 16.11 °C record set in 1995. Researchers at Maynooth University, working with Met Éireann, found that the record warm nights of summer 2025 were made roughly 40 times more likely by human-caused climate change. The day-to-day mean of 16 °C is still cool by US standards, but the practical impact on a trip is meaningful for a few reasons.

• Air conditioning is rare. Most Irish homes, B&Bs, smaller hotels, and pubs do not have AC. Heat tolerance drops fast in unventilated upper-floor rooms during a sustained warm spell. Bring a small USB or battery fan if you sleep hot.
• Warm nights compound heat strain. The summer 2025 records were driven by minimum temperatures rather than maximum daytime highs. Adequate hydration through the evening and a cooler room at night matter more than they would at home.
• Sunburn risk is higher than travelers expect. Even Ireland's typical summer UV index of 6 to 7 burns fair skin in roughly 25 to 30 minutes. The Cliffs of Moher and the open headlands of Kerry and Donegal are particularly exposed; reapply SPF 30+ every two hours and after swimming.
• Weather changes in minutes in the hills. Mist on the Wicklow Mountains, Reeks (Kerry), Twelve Bens (Connemara), and Mournes can drop visibility to a few meters with no warning. Carry a windproof shell, hat, gloves, paper map and compass, headlamp, and extra calories on any multi-hour hike. The Dublin Wicklow Mountain Rescue Team reports that over 30 percent of injuries they attend are lower-leg, often from rolled ankles in bog and scree, so wear boots that support your ankles.
• Cold-water shock matters on the coast. Atlantic water temperatures sit between 9 and 16 °C year-round; even a short fall from a coastal path or pier carries real hypothermia risk. Stay back from cliff edges and unfenced ledges.

Healthcare for non-EEA visitors: what an unplanned hospital visit actually costs

The Health Service Executive (HSE) is Ireland's public healthcare system. Citizens of the EU, EEA, Switzerland, and the UK have reciprocal coverage via the European Health Insurance Card or the bilateral UK-Ireland Common Travel Area agreement. The United States has no reciprocal healthcare agreement with Ireland, so US visitors are billed at full HSE rates for any care they receive.

Costs to plan for, based on HSE and Citizens Information published rates:

• Emergency department (A&E) visit: the standard HSE charge is €100 per visit, though some hospitals have raised the non-EEA visitor charge to as much as €506
• Hospital admission: roughly €800 to €1,500 per night as a private inpatient (the rate non-EEA visitors are billed at)
• Ambulance: charged separately
• Outpatient and follow-up care: billed at full rate

A simple example: a US visitor who sprains an ankle on a Wicklow walk, takes an ambulance to a Dublin A&E, gets X-rays, a splint, and is discharged the same day will commonly see a bill in the €1,000 to €1,500 range before any further follow-up. A two-night admission for an infection or fracture can land at €3,000 to €5,000 before procedures. Medicare does not pay any of this. Most US private insurance plans also do not cover care outside the US, or cover it only on a reimburse-after-the-fact basis with the patient paying upfront.

The fix is travel insurance with medical coverage. For Ireland, a baseline policy should include at least:

• $100,000 to $250,000 in emergency medical coverage
• $100,000 to $250,000 in emergency medical evacuation (relevant if a complex case needs return-to-US transfer)
• Trip cancellation and interruption coverage equal to your prepaid trip cost
• Coverage for adventure activities if you are doing serious hiking, climbing, cycling, surfing, or kayaking

Get travel insurance through Wandr

When you call 999 or 112 for an emergency, ask for ambulance, Garda (police), fire, or coast guard. Mountain rescue operates through the Garda; tell the dispatcher your location, ideally with a grid reference, OS map sheet, or What3Words address.

Bringing your prescriptions into Ireland

Ireland allows visitors to bring up to a three-month supply of prescription medicines for personal use. The Irish Medicines Board and the HSE require the medicines to travel in their original pharmacy containers with your name on the label, accompanied by either the original prescription, a copy of the prescription, or a letter from your prescribing clinician outlining the diagnosis and stating the medicine is for your personal use.

The piece that catches US travelers off guard is the controlled-substance category. Several common US prescriptions sit under Ireland's Misuse of Drugs Act:

• Methylphenidate (Ritalin, Concerta): Schedule 2 controlled drug
• Amphetamine and dextroamphetamine (Adderall, Adderall XR, Dexedrine): controlled; some US-specific formulations are not licensed in Ireland at all
• Lisdexamfetamine (Vyvanse, Elvanse): controlled
• Most opioids: controlled; bring documentation
• Most benzodiazepines: controlled; bring documentation
• Medical cannabis and CBD products: extremely restricted; do not bring without explicit Irish import authorization

Practical packing rules:

1. Carry every prescription medicine in your hand luggage, not checked.
2. Keep it in the original pharmacy bottle or blister pack with the printed label that includes your name, drug, dose, and prescriber.
3. Carry the original written prescription or a recent printout from your pharmacy.
4. Carry a signed letter from your prescriber on letterhead listing each medication, dose, frequency, indication, and a statement that the supply is for your personal use during travel. Date the letter within the last six months.
5. Limit yourself to a 90-day supply, even if you have more at home.
6. If you have any controlled substance and plan to travel beyond Ireland into other EU countries, you may also need a Schengen Form 75 narcotic certificate from your prescriber. The Irish Department of Health publishes guidance on Schengen travel with controlled drugs.

If a US-prescribed medication is not licensed in Ireland (a small number of US-specific formulations), the medicine cannot legally be dispensed locally and you must bring your full supply. Plan for delays or lost luggage by carrying half your supply in your personal bag and half in a checked or partner's bag.

For chronic medications, motion-sickness scopolamine, or a doxycycline standby for tick exposure, a Wandr clinician can review your itinerary and call the prescription in to your local pharmacy for pickup before you fly.

Region-by-region health architecture

Dublin and the major cities (Cork, Galway, Limerick, Belfast)

City travel in Ireland is low risk. Tap water is potable; food hygiene is comparable to US standards. The two background risks are measles (verify MMR before flying) and pedestrian-vehicle risk: traffic in the Republic and Northern Ireland drives on the left, intersections have unfamiliar geometry, and the highest single cause of tourist injury reported in city A&Es is being struck while looking the wrong way at a crossing. Look right first, then left, then right again at every kerb.

The countryside, national parks, and walking routes

Wicklow (Wicklow Way), Kerry (Kerry Way, Reeks, MacGillycuddy's), Connemara (Twelve Bens, Maumturks), the Burren, Donegal, the Mourne Mountains, the Causeway Coast, and the Sheep's Head all fall under the same risk profile: tick exposure, weather changes, and ankle injury. The full tick protocol above applies; pack a paper map and compass; tell someone your planned route and finish time.

Coastal walks and clifftop paths

Cliffs of Moher, Slieve League, the Beara Peninsula, and most of the Wild Atlantic Way include sections with unfenced clifftop paths and exposed headlands. The combination of sudden wind gusts, wet limestone or sandstone, and a hard cold-water consequence means staying well back from edges in any conditions. Cold-water shock can incapacitate a strong swimmer within a minute.

Ferries and islands

Crossings to the Aran Islands, Skellig Michael, Cape Clear, Inishbofin, Tory, Rathlin, and the Saltees can be rough in the Atlantic swell. Motion sickness is common; a scopolamine patch applied four hours before departure or oral meclizine is reasonable for travelers with a history of seasickness.

Festival, pub, and event travel

Trad music sessions in Galway and Doolin, the Galway Races, Electric Picnic, Belfast's Twelfth, All-Ireland Hurling and Football finals, and St Patrick's Day in Dublin all share alcohol-related risk patterns. Standard sense applies: pace alcohol with water, eat before you drink, do not walk along unprotected coastal paths after drinking, and use registered taxis (Free Now in the cities) rather than unmarked cars.

Northern Ireland

Northern Ireland uses the UK's NHS system rather than the HSE. The Charges to Overseas Visitors regulations apply: A&E is free at point of use, but planned secondary care, follow-up clinics, imaging, and admissions are billed. US visitors should carry the same travel insurance into Northern Ireland that they would into the rest of the UK. The Mourne and Sperrin Mountains have the same tick profile as the rest of the island.

Itinerary cheat sheets

Dublin city break (3 to 5 days)

• Verify MMR status
• Standard adult vaccines current (Tdap, flu in season)
• Travel insurance with medical coverage
• Look right first at every street crossing
• Carry your prescriptions with documentation

Dublin plus a countryside or coastal loop (7 to 14 days)

• All of the above
• Treat trousers, socks, and a hat with permethrin before flying
• Pack DEET 30 percent or picaridin 20 percent
• Pack a windproof and waterproof shell, hat, gloves
• Add a daily tick check to your evening routine

Walking holiday (Wicklow Way, Kerry Way, Dingle Way, Connemara, Causeway Coast)

• All of the above
• Add paper map, compass, headlamp, whistle, satellite messenger or PLB for remote sections
• Pre-arrange luggage transfer if you are not carrying a full pack
• Carry a one-day doxycycline standby and a clinician contact plan for any rash or febrile illness post-trip
• Verify your travel insurance covers backcountry walking

Family travel with infants and young children

• Children 12 months and older should have at least one MMR dose; two doses is the goal
• Infants 6 to 11 months traveling to Ireland should receive an early MMR dose at least two weeks before departure
• Carry pediatric paracetamol or ibuprofen in original packaging
• Buggy-friendly cobblestone strategy in Dublin's Temple Bar and Galway's Latin Quarter
• Sun and wind protection on cliff and headland walks

Travelers with ADHD on prescribed stimulants

• Carry a clinician letter dated within six months listing diagnosis, medication, dose, and personal-use statement
• Travel in original pharmacy packaging with your name
• Limit supply to 90 days
• Add a Schengen Form 75 if continuing into the EU
• Plan for the possibility that some US formulations are not interchangeable with Irish equivalents

Food and water safety

Tap water in Dublin, Cork, Galway, Belfast, and the rest of urban Ireland is safe to drink. In rural areas, some private wells (especially in the west and northwest) carry an elevated risk of Cryptosporidium and E. coli contamination, particularly after heavy rain. In a self-catering cottage on a private supply, ask the host whether the water is from a public supply or a well, and consider bottled water for drinking and brushing teeth if the well is untreated.

Food hygiene standards in restaurants, pubs, and cafés are high. The most common travelers' diarrhea triggers are not unsafe food but the trip itself: dietary change, alcohol, jet lag, and shellfish in larger quantities than you eat at home. Oral rehydration salts and a 3-day azithromycin standby (500 mg once daily for 3 days, per CDC guidance for adults) cover the rare moderate-severe case. See our companion piece Ciprofloxacin vs Azithromycin for Traveler's Diarrhea for the antibiotic choice rationale.

Insurance and the cost of one bad day

The single most expensive avoidable mistake on an Ireland trip is skipping travel insurance to save $80. A representative chain of events we see: a US visitor on a Wicklow day walk slips on wet rock, fractures an ankle, calls 999, gets evacuated by mountain rescue and ambulanced into St Vincent's University Hospital A&E in Dublin. The bill: ambulance fees, A&E charge of €100 to €506, X-rays, splint, sometimes a one-night observation at €800 to €1,500. With no insurance, the visitor pays €1,500 to €3,500 out of pocket and writes a complaint to Medicare that goes nowhere because Medicare does not cover any care outside the United States. With a $250,000 medical insurance policy purchased for $40 to $90, the visitor pays a deductible and submits a claim.

For travelers planning serious hiking, cycling, kayaking, surfing, or climbing, ensure the policy specifically includes adventure-sports coverage; some standard travel policies exclude these activities.

FAQ

Do I need vaccines to enter Ireland?

No. Ireland has no entry vaccine requirements for US travelers. The CDC recommends that all travelers be up to date on routine vaccines plus measles-mumps-rubella, hepatitis A, hepatitis B, and an adult polio booster. Verify your MMR status is two documented doses before you fly, because MMR uptake in Ireland is currently 87.6 percent, below the 95 percent level WHO considers protective against outbreaks.

Is the tap water safe to drink in Ireland?

Yes in cities and most rural areas. Dublin, Cork, Galway, Limerick, and Belfast all have public water supplies that meet EU and WHO standards. In rural Ireland, some private wells, especially in the west and northwest, have elevated risk of Cryptosporidium and E. coli after heavy rain. In a self-catering cottage on a private well, ask the host or use bottled water for drinking.

How serious is Lyme disease in Ireland?

The HSE estimates up to 400 cases per year, with 10 to 20 of those being neuroborreliosis. Roughly 5 percent of Irish ticks carry Borrelia. Tick activity peaks April to October, with climate change lengthening the season. Treat clothing with permethrin, wear DEET 30 percent or picaridin 20 percent on skin, tuck trousers into socks in long grass, do daily tick checks, and watch the bite site for 30 days for the bullseye rash. First-line treatment is doxycycline 100 mg twice daily for 10 to 14 days.

How much does an emergency room visit cost in Ireland for a US tourist?

The standard HSE Emergency Department charge is €100 per visit, though some hospitals charge non-EEA visitors as much as €506. A hospital admission runs €800 to €1,500 per night as a private inpatient. Ambulance fees are separate. Medicare does not cover any care outside the US. A baseline travel insurance policy with $100,000 to $250,000 in medical coverage typically costs $40 to $90 per trip.

Can I bring Adderall to Ireland?

Yes, with the right documentation. Ireland allows up to 90 days' personal supply of prescription medicines. For controlled stimulants like Adderall, Vyvanse, Ritalin, and Concerta, carry the medicine in its original pharmacy container, your original prescription or a recent copy, and a signed clinician letter on letterhead dated within six months stating your diagnosis, dose, and that the supply is for personal use. If continuing into the rest of the EU, you may also need a Schengen Form 75 narcotic certificate.

Do I need malaria pills for Ireland?

No. Ireland has no malaria transmission. No prophylaxis is needed.

Do I need rabies pre-exposure vaccine?

No. The Republic of Ireland is free of terrestrial rabies; the only Irish lyssavirus reservoir is a single bat species, with no recorded human cases of bat-derived rabies in modern Irish surveillance. Pre-exposure rabies vaccine is not recommended for standard Ireland travel.

What is the weather like in summer?

Cool by US standards but increasingly warm. Met Éireann confirmed summer 2025 as Ireland's warmest on record at a mean of 16.19 °C. Most accommodation has no air conditioning. Pack layers, a windproof and waterproof shell, sunscreen for unexpectedly bright UV exposure on the coast, and a small fan for sleeping in warm upper-floor rooms.

What number do I call for an emergency in Ireland?

Dial 999 or 112 anywhere in Ireland (both numbers route to the same emergency services). Ask for ambulance, Garda (police), fire, or coast guard. For mountain incidents, request mountain rescue. Have your location ready, ideally as a grid reference, OS sheet, or What3Words address.

Is travel insurance really necessary for Ireland?

Yes. Medicare does not cover care outside the US, most US private insurance offers limited or no overseas coverage, and the HSE bills non-EEA visitors at full rates. A single A&E visit and ambulance can easily reach €1,000 to €1,500. Travel insurance with $100,000 to $250,000 in medical and evacuation coverage usually costs $40 to $90 per trip.

Should I get the seasonal flu shot before traveling to Ireland in winter?

Yes. The CDC recommends annual influenza vaccination for everyone aged 6 months and older. Ireland's flu season runs roughly October through March, overlapping with US peak holiday travel. Get your shot at least two weeks before departure for full immunity.
