The product information for the Comirnaty original COVID-19 vaccine (formerly COVID-19 Vaccine Pfizer/BioNTech) can be found on a separate page.
Comirnaty Original/Omicron BA.1 is a vaccine used for preventing COVID-19 caused by SARS?CoV-2.
It is given to adults and adolescents from 12years of age and older.
Comirnaty Original/Omicron BA.1 is only for individuals who have previously received at least a primary vaccination course against COVID-19.
The vaccine causes the immune system (the bodys natural defences) to produce antibodies and blood cells that work against the virus, so giving protection against COVID-19.
As Comirnaty Original/Omicron BA.1 does not contain the virus to produce immunity, it cannot give you COVID-19.
