  What You Need to Know
  
  • If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection.
  
  • COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.
  
  • You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.
  
  • If you have a weakened immune system due to other diseases or medications, you can receive a COVID-19 vaccine if you have not had a severe or immediate allergic reaction to any of the ingredients in the vaccine.
  
  • People with moderately to severely compromised immune systems should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.
