You book a trip three months out. You're thinking about flights, hotels, itineraries. Vaccinations aren't on the packing list. They're a medical appointment that needs to happen weeks before you leave, and nothing in the booking process reminds you.
The problem gets worse with multi-dose vaccines. Hepatitis B needs three shots over six months. Rabies pre-exposure takes two doses a week apart. Japanese encephalitis needs two doses 28 days apart. If you remember vaccines two weeks before departure, some of these options are already off the table.
The gap between booking a trip and needing to act on vaccinations is the exact kind of thing that falls through the cracks. You know about it. You plan to do it. Then suddenly you're packing and it's too late.
Enter your departure date when you book the trip. You'll get reminded 6-8 weeks before, when there's still time to schedule a travel health appointment.
An email arrives days before your vaccination window closes. Enough lead time to call a clinic, check your insurance, and get your first dose.
If you don't mark it done, you'll get follow-up emails. No silent disappearing after one notification.
The consequences range from inconvenient to dangerous.
Over 100 countries require proof of yellow fever vaccination. Without the certificate, you can be refused entry, quarantined, or vaccinated on the spot at the airport.
What to do if you forgot →Typhoid, hepatitis A, and yellow fever are serious diseases with vaccines that work. Getting sick in a country with limited medical infrastructure turns a vacation into a crisis.
Check your destination →Rabies, hepatitis B, and Japanese encephalitis need multiple doses spaced over weeks. Remembering two weeks out means these are no longer an option.

The CDC recommends scheduling a travel health appointment at least 4-6 weeks before departure. Some vaccines like rabies and Japanese encephalitis require multiple doses over several weeks. If your trip is sooner than 4 weeks out, still see a provider since some single-dose vaccines can be given at the last minute.
Hepatitis B requires 3 doses over 6 months (or an accelerated 3-week schedule). Rabies pre-exposure requires 2 doses over a week. Japanese encephalitis requires 2 doses 28 days apart. Oral typhoid takes 4 capsules over a week. Yellow fever, hepatitis A, and injectable typhoid are single-dose.
It depends on the destination. Some countries require proof of yellow fever vaccination for entry and will deny boarding or quarantine you without it. For other vaccines, the risk is medical rather than legal. Traveling to sub-Saharan Africa or South Asia without recommended vaccines significantly increases your risk of serious illness.
Travel health clinics, primary care offices, and pharmacies like CVS MinuteClinic and Walgreens offer common travel vaccines. Yellow fever vaccine can only be given at CDC-authorized vaccination centers. Use the CDC's clinic finder to locate one near you.
Costs vary widely. Hepatitis A runs $50-100 per dose, typhoid $50-90, yellow fever $150-350, and rabies $250-500 per dose. Many insurance plans cover routine vaccines but not travel-specific ones. Check with your insurer before your appointment.
Set a reminder for 6-8 weeks before your departure date. That gives you enough time to schedule the appointment, get the first dose, and complete any multi-dose series before you leave. If you book trips far in advance, set the reminder when you book.
Free. No account. Enter your trip date and get reminded weeks before departure, when there's still time to schedule your shots.
