Vaccines for Adults

What Can Change Vaccine Guidance for Grown-Ups?

Many things can affect which immunizations an adult may need. Age is a key factor. Children, teenagers, people in their 20s, middle-aged adults, and seniors often need different vaccines or booster shots.

A person’s medical background matters, too. Some illnesses, long-term health problems, or weakened immune systems may mean extra or special vaccines are needed. For example, adults with heart or lung diseases, diabetes, or HIV may require extra protection.

Jobs can also play a role. People who work in healthcare, childcare, or with animals might need vaccinations others do not. Travel plans matter—some countries require or recommend vaccines not usually given in the United States.

Lifestyle choices, such as smoking or living in a group setting like a dorm, may change vaccine recommendations. Whether a person received all recommended childhood shots is important, as missing some vaccines early on can affect what’s needed later. Here are some common factors:

FactorHow It Can Affect Recommendations
AgeDifferent ages require different vaccines.
Health ConditionsSome illnesses call for added precautions.
JobCertain jobs bring higher risk of some diseases.
TravelTrips abroad may need special vaccines.
LifestyleGroup living, smoking, or pregnancy may alter needs.
Vaccine HistoryMissed earlier doses may need catching up.

Each person’s needs can differ, so adults should ask their care provider for advice on what’s right for them.

Ways to Check If Adult Shots Are Current

Keeping vaccine records can be tricky, especially for adults who may not remember every shot from childhood. People can try these steps to learn which vaccines they have already received:

  • Ask parents, caregivers, or guardians if they kept old records, vaccine logs, or paperwork.
  • Contact current and past healthcare providers for copies of the immunization record.
  • Look into school or employer records, as proof of vaccinations may have been required.
  • Contact the state or local health department to check for a vaccine registry.
  • If records cannot be found, a healthcare professional may run blood tests to check immunity to certain illnesses.

If records are missing, repeating some shots is usually safe. Health providers can explain which vaccines can be safely given again. To help keep records from now on, adults can ask for a vaccine log from their clinic. Health teams can update it each time a shot is given. Keeping a written or digital record helps avoid missed or extra doses later. Here’s a helpful checklist for keeping vaccine information in order:

  • Collect any documentation from caregivers.
  • Reach out to doctors, clinics, or schools.
  • Consider blood tests for proof of immunity when records are missing.
  • Start and keep a personal record log for all future vaccines.

Which Immunizations Should Adults Receive?

Adults need several vaccines, some given once and others on a regular schedule. Recommendations may depend on age, health risks, and past vaccine history. The main shots include:

COVID-19 Vaccine

Adults should stay up to date with COVID-19 shots. Getting vaccinated lowers the risk of severe illness, hospitalization, or death. Annual updates and boosters may be needed as the virus changes.

Seasonal Influenza (Flu) Shot

The flu shot is recommended every year for everyone age 6 months and older. For adults over 50, and for those who are pregnant or have long-term illnesses, getting the shot is especially important as influenza can be more dangerous in these groups.

Hepatitis B Immunization

This vaccine protects against a virus that damages the liver. It is recommended for all adults under age 60 and for those 60 and older who have risk factors, such as diabetes or exposure at work. Adults who want extra protection may also get it after age 60.

Human Papillomavirus (HPV) Vaccine

The HPV vaccine is recommended for anyone up to age 26 who did not get it as a preteen or teen. Some adults ages 27 to 45 might benefit, especially if they are at risk. HPV can cause certain cancers, so getting protected is a smart step.

Pneumococcal (Pneumonia) Vaccines

There are two main pneumococcal shots: PCV15 (or PCV20, PCV21) and PPSV23. These protect against infections like pneumonia and meningitis. Adults usually get them at age 65 and above, but some younger adults with health problems may need them earlier.

Vaccine TypeUsual Age/GroupNumber of Doses
PCV15, PCV20, PCV21Adults 65+, some at risk1 (sometimes more)
PPSV23Adults 65+, some at risk1

RSV (Respiratory Syncytial Virus) Vaccine

Adults age 60 and older who are at higher risk for severe RSV may need this vaccine. It is also recommended for most pregnant people in the later stages of pregnancy, especially during RSV season, depending on the region.

Shingles (Herpes Zoster) Vaccine

Shingrix helps prevent shingles, which typically affects older adults. Everyone 50 and older with a healthy immune system should get two doses.

Tetanus, Diphtheria, and Pertussis (Tdap) Vaccine

One Tdap dose is needed in adolescence if not given before. Adults who missed it should get one as soon as possible. After the first Tdap, a Td booster is needed every 10 years to keep up immunity. Pregnant people should get a Tdap dose during the third trimester with every pregnancy.

Summary Table: Key Vaccines for Adults

VaccineMain PurposeWho Needs ItFrequency
COVID-19Virus preventionAll adultsAs recommended
Influenza (Flu Shot)Flu preventionAll adults yearlyOnce a year
Hepatitis BLiver protectionAdults under 60, at-risk 60+Series (usually 3 shots)
HPVCancer preventionAll through age 26, some 27-45Series (2-3 shots)
PneumococcalPneumonia preventionAdults 65+, younger at-riskOne or more doses
RSVPrevent severe RSVAdults 60+, pregnant at certain timesOne dose
ShinglesPrevent shinglesAdults 50+Two doses
Tdap/TdPrevent tetanus/diphtheria/pertussisAll adultsTdap once, then Td booster every 10 years

Adults should talk with their healthcare team about which vaccines are best for them. Keeping a personal vaccination record helps track which shots have been received and when the next ones are due.
