Essential Information on COVID-19 Vaccines
  • All available COVID-19 vaccines are highly effective at preventing severe illness, hospitalization, and death due to COVID-19, including from the Delta variant.
  • The COVID-19 vaccines available in the United States meet the FDA’s rigorous standards for safety and effectiveness.
  • After getting vaccinated, it’s possible you might have pain and swelling in the arm where you received the shot. Other side effects include headache, fever, feeling tired, and muscle pain. These are usually mild and should last at most a few days.
  • Until you’re fully vaccinated (2 weeks after your final dose), you should continue to wear a mask inside public places (even vaccinated people in areas of substantial or high spread of COVID-19 should wear a mask inside public places to maximize protection from the highly contagious Delta variant and prevent possibly spreading it to others) and stay at least 6 feet apart from people who don’t live with you and who may not be vaccinated.
  • If you meet the criteria for having a compromised immune system, you should get a third dose of the Pfizer-BioNTech or Moderna vaccine. See the latest guidance.
  • All vaccinated people age 18 and older should get a booster shot as soon as you’re eligible to keep up your protection against COVID-19. See the latest guidance on boosters.
  • The COVID-19 vaccine is free of charge to all people living in the United States, regardless of your immigration or health insurance status.
