How does this medication work? What will it do for me?
The COVID-19 vaccine (Recombinant protein, Adjuvanted) belongs to a group of medication known as vaccines. It is used to prevent infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in people 12 years of age and older.
The COVID-19 vaccine (Recombinant protein, Adjuvanted) increases a person's defenses against the SARS-CoV-2 virus by introducing protein fragments that look like the spike protein of the virus. This protein triggers the body to produce antibodies, cells that are designed to attack the virus in the body. The antibodies stay in your body, ready to attack future SARS-CoV-2 virus that enters the body. The vaccine does not contain the actual virus and cannot give you COVID-19.

These factors may affect how you should use this medication.
Allergic reactions: Rarely, this vaccine may cause severe allergic reactions.
