COMIRNATY Concentrate for dispersion for injection (30 mcg) is indicated for active immunisation to prevent COVID-19 caused by SARS-CoV-2 virus, in individuals 12 years of age and older.
COMIRNATY 10 mcg Concentrate for Dispersion for Injection is indicated for active immunisation to prevent COVID-19 caused by SARS-CoV-2 virus, in children aged 5 to <12 years old.
The use of this vaccine should be in accordance with official recommendations.​​

Mechanism of action

The nucleoside-modified messenger RNA in Comirnaty (tozinameran) is formulated in lipid nanoparticles, which enable delivery of the non replicating RNA into host cells to direct transient expression of the SARS-CoV-2 S antigen. The mRNA codes for membrane-anchored, full-length S with two point mutations within the central helix. Mutation of these two amino acids to proline locks S in an antigenically preferred prefusion conformation. The vaccine elicits both neutralizing antibody and cellular immune responses to the spike (S) antigen, which may contribute to protection against COVID-19.
