COVID vaccines help protect you from severe illness, hospitalization, and death due to COVID-19.

It’s important to stay up to date with your vaccines to keep up your protection.

How long does it take for the vaccines to be effective?

Your vaccine is effective 2 weeks after you’ve gotten all your recommended initial doses. 

When am I best protected with a COVID vaccine?

You’re best protected when you’re up to date with your COVID vaccines. That means you’ve gotten all recommended doses, including any booster doses when the time comes.

Do vaccinated people need to wear masks indoors?

To maximize protection from highly contagious variants and prevent possibly spreading COVID to others, wear a well-fitting mask over your nose and mouth inside public places when the COVID risk to your community is high.

Vaccinated and unvaccinated people must still follow state, local, tribal, and territorial laws, rules, and regulations. That includes public transportation, airport/airplane, local business, and workplace guidance. CDC recommends that everyone ages 2 and older wear a mask on public transportation and while in airports and stations.

What should unvaccinated people do to protect themselves and others from COVID?

For the best possible protection from COVID, get vaccinated and stay up to date with your vaccines.

Until you’re vaccinated, wear a well-fitting mask over your nose and mouth inside public places when the COVID risk to your community is high.

If you’re at higher risk of getting very sick from COVID, you can also protect yourself by:

  • Keeping at least 6 feet away from people who don’t live with you.
  • Avoiding crowds and poorly ventilated spaces.
  • Washing your hands often with soap and water for at least 20 seconds or using hand sanitizer with at least 60% alcohol if you don’t have soap and water.

Public health officials continue to update recommendations for both vaccinated and unvaccinated people. For the latest guidance, visit cdc.gov/coronavirus.
