There are currently three types of COVID-19 vaccines available: mRNA, viral vector, and inactivated vaccines.

  • mRNA vaccines: These vaccines use a small piece of genetic material called messenger RNA (mRNA) to teach cells how to make a protein that triggers an immune response. The two mRNA COVID-19 vaccines currently available are the Pfizer-BioNTech vaccine and the Moderna vaccine.
  • Viral vector vaccines: These vaccines use a modified virus (not the coronavirus that causes COVID-19) to deliver a piece of genetic material that triggers an immune response. The Johnson & Johnson COVID-19 vaccine is an example of a viral vector vaccine.
  • Inactivated vaccines: These vaccines use a weakened or inactivated form of the virus that causes COVID-19 to trigger an immune response. The Sinovac and Sinopharm COVID-19 vaccines are examples of inactivated vaccines.

There are four types of COVID-19 vaccines currently available in the U.S.:

  • mRNA vaccines: These vaccines teach your cells how to make a protein that is found on the surface of the COVID-19 virus. When your immune system sees this protein, it learns how to fight off the virus. The mRNA vaccines are made by Pfizer-BioNTech and Moderna.
  • Viral vector vaccines: These vaccines use a harmless virus to deliver genetic material from the COVID-19 virus to your cells. When your immune system sees this genetic material, it learns how to fight off the virus. The viral vector vaccine is made by Johnson & Johnson.
  • Protein subunit vaccines: These vaccines contain pieces of the COVID-19 virus protein. When your immune system sees these pieces of protein, it learns how to fight off the virus. The protein subunit vaccine is made by Novavax.

These vaccines are all safe and effective. They have been rigorously tested and monitored, and they have been shown to protect against COVID-19. The most common side effects of these vaccines are mild and go away on their own within a few days.

If you are eligible for a COVID-19 vaccine, I encourage you to get vaccinated. Getting vaccinated is the best way to protect yourself from COVID-19 and its serious complications.
