How does this medication work? What will it do for me?
This medication belongs to a group of medications known as vaccines. It is used in people 18 years of age and older to prevent coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus. This vaccine increases a person's defences against coronavirus infection by introducing genetic information, in the form of messenger RNA, for a piece of virus into the body. This causes your body to produce pieces of the virus which then stimulate the production of your own antibodies (cells designed to attack that particular virus). These antibodies remain in the body ready to attack any future SARS-CoV-2 virus that may cause infection.You cannot get COVID-19 from the vaccine.
The Moderna COVID-19 mRNA Vaccine has been granted authorization for sale under an Interim Order.
