Yes, you can and should vaccinate after the due date. Missing a dose does not mean you have to restart a vaccine series, as the body retains immune memory. You should arrange for "catch-up" vaccines as soon as possible to ensure protection.

Delaying a shot outside the recommended schedule leaves children vulnerable to diseases when they are most at risk of getting ill, developing serious complications — or dying — if they contract it.

What happens if a vaccination is missed?

Don't panic. Studies show that delayed vaccines can still be safely and effectively continued using a catch-up immunization schedule.

Is it ever too late to vaccinate my child?

If your child has missed a dose of one or more vaccines, talk to your child's doctor about getting catch-up vaccines. In some cases, an additional vaccine may need to be given if the timeframe between doses has been too long but it's never too late to start or complete a series of immunizations.

What are the consequences of not vaccinating your child?

a vaccine-preventable disease

Vaccination in childhood prevents serious illness and lifelong disability from certain vaccine-preventable diseases (VPDs). People not vaccinated as children are vulnerable to VPDs and their consequences as adults.

What is the 3 2 1 rule for vaccines?

The "3-2-1" rule is a guideline for monitoring lumps at feline vaccination sites, indicating a lump needs veterinary investigation if it's still present 3 months after vaccination, is larger than 2 cm, or is growing larger 1 month after appearing. This rule helps identify potentially dangerous injection-site sarcomas, rare tumors that can develop in cats, prompting biopsies for suspicious masses. 

What is the minimum time between vaccines?

The minimum interval between vaccine doses varies by vaccine type, but commonly ranges from 4 weeks (28 days) for live vaccines (like MMR, Varicella) or different COVID-19 vaccines, up to several months for certain COVID-19 boosters or specific series (like Hepatitis A), with intervals often extending to 8 weeks or more for some adult COVID-19 doses to reduce myocarditis risk. Key intervals include 4 weeks for different live vaccines, 8 weeks for some COVID-19 second doses, and 6 months for COVID-19 boosters, but always check the specific vaccine schedule, as doses given too early (within 4 days before) might be valid, while those much earlier may need repeating.

What happens if I vaccinate my baby late?

Delaying a baby's vaccinations leaves them vulnerable to serious, potentially deadly infections like whooping cough or measles, as their developing immune systems are most at risk during infancy, increasing the chance of hospitalization, severe complications, or death; it also reduces community protection (herd immunity) by spreading the disease to others, like newborns too young for shots, according to Kaiser Permanente, the CDC, UNICEF, and the University of Maryland. 

When is it too late for vaccines?

You're never too old to get vaccinated! Getting vaccinated is a lifelong, life-protecting job. Don't leave your healthcare provider's office without making sure you've had all the vaccinations you need.

If the error is detected the same day, a repeat dose can be administered that day.

What if my child misses a vaccination?
