    There is a lot of information about the new COVID-19 vaccines. You may be excited about the vaccine. But you may also be a little nervous about it.

    This section of our website is dedicated to helping you understand how these vaccines work and answering any questions you may have about their safety. 

    Let's look at the what the vaccines are, how they work, and how they were made.


    • Vaccines have been and are being created to prevent infection with SARS-CoV-2, the virus that causes COVID-19.
    • There are currently two vaccines available.
    • Both vaccines are mRNA vaccines - which is a newer type of vaccine.
    • mRNA vaccines DO NOT contain any
      • Virus - live, weakened, or dead
      • Bacteria or other toxins
      • Preservatives - including thimerasol
      • Eggs
      • Stem cells or fetal tissue
      • Biological ingredients
    • The current vaccines DO NOT contain the virus and they CANNOT make you sick with COVID-19.
    • Both Pfizer and Moderna vaccines are two dose vaccines:
      • Pfizer - you must get your second dose 21 days after the first.
      • Moderna - you must get your secon dose 28 days after the first.
    • You must get the second dose to get the best immunity.
    • After the second dose, both vaccines are about 95% effective at preventing COVID-19 infection.
