📋 Catch-Up Schedule Principles

If your child has missed any vaccines, catch-up vaccination is straightforward. The CDC publishes a complete catch-up schedule for children 4 months through 18 years. Key principles:

✅

Start at any age

Most vaccines can be started at any age — you do not need to restart a series from scratch. Partial series still count.

⏱

Minimum intervals still apply

Doses given too close together may not provide full immunity. Your provider will calculate the correct spacing.

🎯

Prioritize early-risk vaccines

Pertussis, Hib, and PCV protect infants most during early months. Catch up as quickly as possible for these.

🔗

Combination vaccines help

Combination vaccines like Pediarix (HepB+DTaP+IPV) and Pentacel (DTaP+IPV+Hib) can reduce total injections during catch-up.

🧑 Adult Vaccine Schedule

Vaccine protection doesn't stop at childhood. Adults need ongoing boosters and new vaccines as they age.

Tdap / Td

Tdap once (if never received), then Td every 10 years. Tdap each pregnancy (27–36 weeks).

Tetanus immunity wanes; pertussis protection needed to protect newborns.

Influenza

Every year, ideally September–October before flu season.

Flu strains change annually; prior immunity doesn't fully protect against new strains.

COVID-19

Updated booster annually per current CDC guidance.

Protection wanes; updated formulations better match circulating variants.

Shingles (Shingrix)

2 doses at age 50+; 2–6 months apart.

Varicella virus reactivates as shingles in 1/3 of adults. Shingrix is 90%+ effective.

Pneumococcal (PCV20/PPSV23)

PCV20 once at age 65+ (or earlier for high-risk conditions).

Pneumococcal pneumonia causes ~150,000 hospitalizations/year in US adults.

RSV (Abrysvo/Mresvia)

Single dose at age 60+; or during pregnancy (32–36 weeks) to protect newborn.

RSV causes 60,000–160,000 hospitalizations/year in adults 65+.

Hepatitis B

3-dose series for all unvaccinated adults; Heplisav-B is a convenient 2-dose adult option.

Many adults were never vaccinated; hepatitis B remains a significant cause of liver cancer.
