COVID-19: Vaccines Fast Facts

COVID has taken many human lives. It is now the 3rd leading cause of death in the United States, just after heart disease and cancer.

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

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.
