Dr. Theresa Tam, Canada’s chief public health officer, said Friday that the National Advisory Committee on Immunization (NACI) has provided updated guidance on booster shots for children aged five to 11 and for adolescents aged 12-17. NACI now strongly recommends that children ages five to 11 years receive a complete dose of the primary series of the Pfizer ten microgram pediatric MRNA COVID-19 vaccine with at least eight weeks between the first and second dose. NACI is also recommending a third dose for moderately to severely immunocompromised children in the age group.
