No, vaccine doses are based on age not weight.
Children five to 11 years of age (born in 2016 or earlier and turning five in 2021) are recommended to receive the paediatric dose of Pfizer (10 mcg dose). Adolescents 12 years of age and older should continue to receive the 30 mcg dose of the Pfizer vaccine. Please book your child at the appropriate clinic based on their age.
Children who receive the paediatric dose (10 mcg dose of Pfizer vaccine) for their first dose and then turn 12 years of age by the time the second dose is due may receive the adult dose (30 mcg dose of Pfizer vaccine). They may also receive a paediatric dose for their second dose, if preferred.
