Pfizer-BioNTech COVID-19 Vaccine is a monovalent COVID-19 vaccine that is authorized for emergency use to prevent COVID-19 as:
The first two doses of the three-dose primary series for children 6 months through 4 years of age.
A two-dose primary series for individuals 5 years of age and older.
A third primary series dose for individuals 5 years of age and older who have been determined to have certain kinds of immunocompromise.> Comirnaty is a monovalent COVID-19 vaccine that is approved for use as a two-dose primary series for the prevention of COVID-19 in individuals 12 years of age and older.
And booster jabs are about all that has been happening for years. Same for Moderna.
