Shot protects against the most prevalent subvariants of Omicron, BA.4 and BA.5
Health Canada approved a COVID-19 vaccine booster for children on Friday that targets more recent variants of the coronavirus, along with the original strain
The Pfizer-BioNTech bivalent
shot protects against the most prevalent subvariants of Omicron, BA.4 and BA.5, and is the first approved for use in children ages five to 11
In a press release, Health Canada said that after thorough review it has found the vaccine is safe and effective and that its benefits outweigh any potential risks when used as a booster dose
The child-sized dose is about a third of the dose that is approved for people over the age of 12
The National Advisory Committee on Immunization strongly recommends children with weakened immune systems or underlying medical conditions be offered a dose of the new vaccine at least six months after they receive their first two COVID-19 shots
The recommendation for other children in that age group is more discretionary, and NACI suggests the bivalent booster may be
offered
For now, kids aged five to 11 are only recommended to get one COVID-19 booster shot, though NACI says an extra booster could be considered at the discretion of family doctors for children who are at higher risk
At this time, it is not assumed that every child will need a COVID-19 booster dose but they are particularly important for children five years of age and older with underlying conditions that place them at high risk of severe illness from COVID-19,
Dr. Shelley Deeks, chair of NACI, said a statement
She said the new vaccine is preferred as a booster for kids because it is expected to perform at least as well as the original booster and may have extra benefits against newer variants
NACI now also recommends that COVID-19 vaccine boosters can be given to children at the same time as other routine vaccines like the flu shot without a waiting period in between. Deeks said in her statement that she hopes the new recommendation will help children catch up on shots they may have missed during the pandemic
Canada’s chief public health officer, Dr. Theresa Tam, said in a statement that most children who catch COVID-19 experience only mild illness, and the risk of being hospitalized is lower for vaccinated children than those who are unvaccinated
The Omicron wave of the pandemic has seen far more children infected with COVID-19 than previous waves, given the high level of infection overall, she said
No unexpected safety concerns were flagged with the new vaccine in the five to 11 age group
Pfizer-BioNTech must continue to provide data from ongoing studies and real-world use of the vaccine to Health Canada to make sure the benefits continue to outweigh any risks, and to alert the drug regulator to any new safety concerns
Health Canada and the Public Health Agency of Canada say they will keep a close eye on the safety of the vaccine in Canada and internationally
