Vaccinations
Vaccinations are highly effective, convenient, and the safest preventive care in protecting yourself against certain serious diseases as well as defeating the spread of them. Vaccines can also help prevent serious complications from diseases.
Adults need to keep their vaccinations up to date because there is increased susceptibility to certain diseases in adulthood and immunity from childhood vaccines can wane over time.
It is recommended that adults stay up to date with the following routine vaccinations:
- COVID-19 vaccine
- Influenza (flu) vaccine every year
- Td or Tdap vaccine
You may need other vaccines based on your age, health conditions, job, lifestyle, or travel habits and some vaccines may be required for school or work. Learn more about what other vaccines may be recommended for you and talk to your healthcare professional or USC Student Health about which vaccines are right for you.
