Health Canada authorized the shots for children ages 5 to 11. And as in the U.S., the doses will be just a third of the amount given to teens and adults.
“A longer interval between doses leads to stronger immunity,” said Howard Njoo, the deputy public health officer of Canada.
The government agency said the vaccine is 90.7% effective in preventing COVID-19 in children and no serious side effects were identified.
“After a thorough and independent scientific review of the evidence, the Department has determined that the benefits of this vaccine for children between 5 and 11 years of age outweigh the risks,” Health Canada said in a statement.
The agency also said that Canadians and permanent residents returning from the U.S. or other nations after trips of less than 72 hours no longer need to show a negative PCR test when returning. A rapid antigen test will suffice starting on Nov. 30.
The PCR test will still be required after longer trips and for fully vaccinated travelers from the U.S. or other countries, though Canada’s Health Minister Jean-Yves Duclos said officials will soon provide an update for Americans.
“It is very important.I am glad they are making it easier," said Sandy Pearce, who lives in Fort Erie, Ontario, and wants to travel more easily to New York state to help her parents, who are in their 90s.
“They need help and now I can go over for a day trip or even just for a few hours,” she said, and added, "It’s also a tremendous boost for the U.S. economy, especially for the holiday shopping.”
While PCR tests are more sensitive, experts say the antigen tests are highly effective at detecting infectious levels of virus, are much cheaper and don't require waits that can sometimes extend for days.
In the U.S., the White House said Wednesday that about 10% of eligible children aged 5 to 11 have received a dose of the Pfizer COVID-19 vaccine since the U.S. approval for their age group two weeks ago.
At least 2.6 million kids have received a shot, White House COVID-19 coordinator Jeff Zients said Wednesday, with 1.7 million doses administered in the last week alone, roughly double the pace of the first week after approval.
Canada is expecting an accelerated delivery of 2.9 million child-sized doses, enough for a first shot for every child in the 5 to 11 age group. In a statement Friday, Pfizer said the vaccines would be shipped to Canada “imminently.”
Dr. Andrew Morris, a professor of infectious diseases at the University of Toronto and the medical director of the Antimicrobial Stewardship Program at Sinai-University Health Network, said delaying a second dose for eight weeks probably means a lower myocarditis risk and theoretically a better immune boost. He said there are extremely rare side effects, including myocarditis, a type of heart inflammation that occasionally occurs after the second dose.
The Government of Canada is also announced that as of Jan 15. professional and amateur athletes visiting Canada must be fully vaccinated. Major League Baseball the NBA received national exemptions for those on the teams who were not vaccinated.
