Which vaccines are recommended?
The answer depends on age, health, pregnancy, previous vaccination, and other circumstances. Start with the group that applies to you.
What are you looking for?
Choose the question closest to yours. You can then see current recommendations and who issued them.
Children & teens
Current vaccine recommendations from pediatric, family medicine, and federal sources.
See child & teen guidance →Adults
Current recommendations based on age, health conditions, and other risk factors.
See adult guidance →Pregnancy
Current maternal immunization recommendations.
See pregnancy guidance →What does my child need for school?
See Pennsylvania’s current school immunization requirements.
See PA requirements →Have questions about a recommendation?
That’s a good reason to look more closely. You may want to know why a vaccine is recommended, what evidence supports it, what the benefits and risks are, how safety is monitored, or whether the recommendation applies to you or your child.
ACIC’s goal is to connect you with evidence-based information that helps answer those questions clearly.
Go to the current source
ACIC does not reproduce vaccine schedules here. We link to the organizations responsible for maintaining the guidance so you can check the current recommendation directly.
Children & teens
Vaccines are recommended throughout childhood and adolescence to protect against serious vaccine-preventable diseases. Current guidance is available from the sources below.
Adults
Vaccination does not end in childhood. Adult recommendations may depend on age, health conditions, previous vaccination, occupation, travel, and other risk factors.
Pregnancy
Vaccine recommendations during pregnancy consider protection for the pregnant patient and, for some vaccines, protection passed to the infant.
Pennsylvania school requirements
A medical recommendation and a school requirement are not the same thing. Pennsylvania law and regulations determine immunization requirements for school attendance in the Commonwealth.
A few questions you may have
Vaccine recommendations can be more complicated than a simple yes-or-no list.
Why would vaccine recommendations change?
Recommendations can be updated when new evidence becomes available, disease patterns change, vaccines or formulations change, or an organization reviews how the benefits and risks apply to a particular population.
A change in a recommendation does not automatically mean the underlying science was wrong. It can reflect new evidence, new circumstances, or a different application of existing evidence.
Why might two credible organizations have different recommendations?
Organizations may have different responsibilities, review evidence on different timelines, or reach different conclusions about how evidence should be translated into clinical or public health guidance.
Look at who issued the recommendation, when it was updated, who it applies to, and the evidence and process behind it.
How do I know whether a recommendation applies to me?
Age is only one factor. Health conditions, pregnancy, previous vaccination, medications, occupation, travel, and other circumstances can affect vaccine recommendations.
If you are unsure, ask a qualified healthcare professional to help interpret the current guidance for your situation.
What if my question is really about vaccine safety?
Questions about side effects, ingredients, safety monitoring, testing, or specific safety concerns deserve direct answers.

How ACIC chooses vaccine information
ACIC prioritizes credible medical, scientific, professional, public health, and Pennsylvania sources. We look for information grounded in scientific evidence, clinical expertise, transparent evidence review, and credible public health practice.
When credible guidance differs, our goal is to identify the source clearly and help users understand what kind of guidance they are reading rather than blur meaningful differences.
