COVID-19 Vaccines: Questions and Answers

How safe are the COVID-19 vaccines?

According to the Centers for Disease Control, the COVID-19 vaccines are all safe and effective. In the United States, millions of people have received vaccines, and the CDC recommends you get vaccinated as soon as possible.

Are the COVID-19 vaccines expensive?

The federal government is providing all COVID-19 vaccines free of charge.

How do COVID-19 vaccines work?

There are different types of vaccines and each works to protect the body in a different way. All vaccines leave the body with a supply of "memory" T-lymphocytes and B-lymphocytes that remember how to fight future COVID-19 infections.

How many types of COVID-19 vaccines are there?

According to the CDC, there are currently three main types of COVID-19 vaccines.

  • mRNA vaccines (including Pfizer-BioNTech and Moderna) use material from SARS-CoV-2, the virus that causes COVID-19, to give our cells instructions for how to make a harmless protein that is unique to the virus. After making copies of the protein, our bodies destroy the genetic material from the vaccine. Our bodies then recognize the protein doesn't belong and build T-lymphocytes and B-lymphocytes that will remember how to fight SARS-CoV-2 in the event of a future infection.
  • Protein subunit vaccines contain harmless proteins found in SARS-CoV-2, the virus that causes COVID-19, instead of the entire virus. After being vaccinated, our bodies recognize that the protein should not be there and will begin building T-lymphocytes and antibodies that remember how to SARS-CoV-2 if infected in the future.
  • Vector vaccines (including Johnson & Johnson's Janssen) contain an altered version of a different virus than the one that causes COVID-19. Inside the shell of the altered virus, there is material from SARS-CoV-2, the virus that does cause COVID-19. This material is called a viral vector. The genetic material inside the viral vector gives our cells instructions to make a protein that is unique to SARS-CoV-2. With these instructions, our cells make copies of the protein. Our bodies then build T-lymphocytes and B-lymphocytes that remember how to fight that virus if we are infected again.
