What Are Vaccines?
Created in laboratories by specialized scientists, vaccines help prevent serious diseases, including COVID-19, polio, measles, mumps, shingles, chickenpox and many more.
Vaccines have greatly reduced or eliminated life-threatening diseases that used to kill or disable millions of children and adults.
Depending on the vaccine, you may receive it:
- By injection (shot)
- Through a nasal spray
- Orally (drops)
