This vaccine uses mRNA (messenger ribonucleic acid) to give the "code" for the body to make antibodies to this virus. These antibodies help fight the virus if exposed at a later date. The vaccine can help prevent a COVID-19 infection or to make the infection much milder than it would be otherwise.

Do not use if you are allergic to any of the components of this vaccine. 

Vaccination should be postponed if you have an acute severe illness with a fever. If is a mild illness with no fever, vaccination may proceed.

If you have a bleeding disorder in which intramuscular injections are not recommended, you should not receive this vaccine.

Although this vaccine is safe for most people:

• If you have cancer, consult with your cancer care team before receiving vaccinations
• if you have a condition or are on a medication that weakens your immune system, consult your healthcare providers before getting vaccinated.

Use in pregnancy and breastfeeding: It is highly recommended that pregnant and breastfeeding individuals receive COVID-19 vaccination.  mRNA COVID-19 vaccines (such as this one) are preferred on account of more safety data.
