Since the start of Canada’s vaccine rollout, more than 6,000 Canadians have reported contracting COVID-19 after receiving the first dose, according to the Public Health Agency of Canada (PHAC).
203 people were hospitalized and 53 died of COVID-19 after getting one shot of the vaccine. 58% of people hospitalized are 80 years or older. 91% of the dead are 80 years or older, the rest are 50-70 years old.
Data from Public Health Canada analyzed the number of COVID-19 infections, deaths and hospitalizations that were reported after a person received the first dose of the vaccine.
The numbers show that a “vast majority of cases are occurring among unvaccinated individuals, and supporting the benefits of the extended second dose strategy,” a Public Health Agency of Canada spokesperson told Global News in an email.
As of April 26, 6,789 people who had already received one shot of a COVID-19 vaccine were infected with the coronavirus, according to PHAC. Most of those cases — 4,517 — were reported within 14 days of the first vaccine dose. The rest — 2,274 — were reported more than two weeks after the first dose. This represents 1.3 per cent of cases reported since the vaccine rollout in December, PHAC said.
According to Ontario Public Health, the Pfizer and Moderna vaccines are approximately 60 to 80% effective in preventing COVID-19 three to four weeks after a person is given the 1st dose.
Among the 2,274 people who contracted COVID-19 cases within two weeks of a vaccine, 9.3 per cent of people were hospitalized and 2.4 per cent died, the data showed.
Two weeks after receiving one dose of a coronavirus vaccine, people received “significant protection” from hospitalization and death compared to unvaccinated people, PHAC said.
Among the 203 people who were hospitalized, 77 per cent received the Pfizer vaccine, 22 per cent received the Moderna vaccine and one per cent received the Covishield vaccine.
As of Monday, 13.9 million Canadians have received at least one dose of the coronavirus vaccine. There have been 1.2 million reported COVID-19 cases in Canada to date.
