Frequently Asked Questions about COVID-19 Vaccines
COVID-19 vaccination is the safest and most effective way to protect against severe disease and death from COVID-19.
The Centers for Disease Control and Prevention (CDC) recommends a 2024-2025 COVID-19 vaccine for most adults age 18 or older.
It is especially important to get a 2024–2025 COVID-19 vaccine if you are age 65 or older, are at high risk for severe COVID-19, or have never received a COVID-19 vaccine.
For adults age 65 years and older and those who are moderately or severely immunocompromised, CDC recommends a second dose of 2024-2025 COVID-19 vaccine, to be given 6 months after the first dose.
