The CDC has released a recommendation that all adolescents 12-17 be offered booster vaccines using only the Pfizer COVID-19 vaccine, at least 5 months following the primary series
The CDC guidelines follow the review of unpublished Israeli data of 12-15 year olds vaccinated 5-6 months prior showing an equivalent infection rate to unvaccinated, and that those who receive boosters are at about 1/3 of the risk
Health Canada has not yet approved booster doses for general use in 12-17 year olds, however NACI has recommended that boosters, at least 6 months following the primary series, should be considered for the following groups within that age group
o Those with an underlying medical condition at high risk of severe illness due to COVID-19 (including those who are immunocompromised and received a 3-dose primary series)
o Those who are residents in congregate settings (e.g. shelters, group homes, quarters for migrant workers, correctional facilities)
o Those who belong to racialized and/or marginalized communities disproportionately affected by COVID-19
