MODERNA ASKS HEALTH CANADA TO AUTHORIZE BOOSTER

-

U.S. drugmaker Moderna is asking Health Canada to authorize a booster shot of its COVID-19 vaccine. The company submitted data on a booster shot that is half the size of the doses used to give first and second shots of the vaccine so far. Last month Moderna said there were signs immunity was waning the longer people got from their doses. Public health and vaccine experts in Canada are leery of recommendi­ng booster shots for most Canadians because the vaccines thus far are showing to maintain strong protection against severe disease even if protection against infection at all is dropping. The National Advisory Committee on Immunizati­on said in late September a third dose of vaccine was warranted for people in long-term care homes or with compromise­d immune systems.
