Vaccines

This type of vaccine uses a live virus that has been weakened or altered in some way.

• Toxoid vaccine

• mRNA vaccine

• Attenuated vaccine

• Inactivated vaccine

The first vaccine that was developed was for

• chickenpox

• polio

• rubella

• smallpox

mRNA vaccines work by

• introducing inactivated virus into the body to start an immune response.

• having your own cells make a protein from the virus so your immune cells will recognize the virus.

• changing the DNA of your cells to protect you from infection from the virus.

• using a carrier virus to start an immune response.

• mRNA, spike protein

Vaccines that introduce a small piece of the virus to the host are known as

• toxoid vaccines

• subunit vaccines

• inactivated vaccines

• mRNA vaccines

Can someone who has already coronavirus become infected again?

• Yes

• No

• I'm not sure

Answer explanation

Researchers are not entirely sure if people can become infected again. People who have had the virus do have antibodies, but they do not seem to last as long as those generated by the vaccine.

When the vaccine becomes available for teenagers, do you feel comfortable receiving it?

• Yes

• No

• I'm not sure yet
