Most adults are behind on at least one booster and don't know it. The flu shot, Tdap, COVID, shingles — they all come due on different schedules. Set a reminder now and get notified before your next one is overdue.
Done in seconds. No sign-up required.
Not from neglect — from not knowing when it was due.

Childhood vaccines come with a schedule your doctor tracked. Adult boosters don't have that safety net. No one calls you when your Tdap is due. Your pharmacist doesn't know when you last got a tetanus shot. The interval is 10 years, which sounds memorable until it isn't.
The flu shot is annual, COVID boosters evolve yearly, shingles is a two-dose series for adults over 50, pneumococcal vaccines have age-based eligibility windows. Each one runs on its own clock. Tracking them manually requires either an excellent memory or a system.
A reminder set the day you get a booster — targeting your next due date — removes that tracking burden entirely. You don't have to remember. The email finds you.
These are the vaccines that come due after childhood — and the ones most adults are behind on.
For the full adult schedule with all eligibility details, see our adult vaccine booster schedule guide.
The best time to set your next booster reminder is the same day you get a shot. You know the date. You know the interval. Take 30 seconds to lock it in.
Got a Tdap today? Set a reminder for 10 years from now. Flu shot in September? Set it for next September. The date drives everything.
Emails arrive 7, 3, and 1 day before your date — enough time to book a pharmacy or clinic appointment before slots fill.
After you get the shot, click "I did it" in the email and immediately set your next one. The cycle stays unbroken.
Schedule details, what happens if you're overdue, and how to find your vaccination history.
The main ones: Tdap or Td every 10 years, flu shot every year, COVID booster annually or as recommended, shingles vaccine (Shingrix) as a two-dose series for adults 50+, and pneumococcal vaccines for adults 65+. See the full schedule at our adult booster schedule guide.
Enter your booster date and email. BoldRemind sends you reminders 7, 3, and 1 day before, then again on the day, with follow-ups until you mark it done. No app, no account, no password required.
Yes. Immunity from the original vaccine series wanes over time regardless of how you feel. Boosters restore that protection before it drops enough to matter. Feeling fine is not a sign that last year's shot is still working.
Most can be delayed without restarting the series, but the gap in protection is real. A Tdap booster given 11 years after the last one, for example, still works — you just had a year of reduced immunity. Sooner is always better.
Check your vaccination records to find the date of your last dose, then add the recommended interval. For flu it's annually, Tdap is every 10 years, COVID is once per season. If you've lost your records, your doctor or state immunization registry can help.
Start by checking your doctor's patient portal, your state's immunization information system (IIS), or your childhood school records. Pharmacies like CVS and Walgreens also keep records of any shots they administered. See our guide on tracking vaccine records.
Free. No account. Takes 30 seconds. You'll get an email days before your booster is due — and follow-ups until it's done.
