CANADA HAS CONTRACTS FOR UP TO 100 MILLION PFIZER AND MODERNA DOSES IN 2022

By Chandrayee Roy Choudhury, Canada 

Federal COVID-19 vaccine contracts mean Canada should get enough doses to give two or three more mRNA shots to every Canadian, every year until at least 2024.

But even as the National Advisory Committee on Immunization is now suggesting some Canadians get in line for the fourth dose of vaccine, the World Health Organization is warning “repeated booster doses of the original vaccine composition” are not a sustainable plan to end the pandemic.

The contracts back up Prime Minister Justin Trudeau’s statements Monday that Canada will have enough doses for third and even fourth shots if they become necessary.

With a population of 38 million people, that is more than two doses per person, per year, for a country where 77 per cent of the population already has the two doses required, and 27 per cent have now received a third dose.

Murthy ,a British Columbia Pediatrician and Co- Chair of the WHO's clinical research committee, said with Omicron there is some data that suggests a third dose is doing better at preventing infection outright than the original two doses, but he said there is no evidence a fourth dose is helping at all.
