Canada approves the use of Johnson & Johnson’s vaccine and attributes its efficacy of 66.9%
–
The North American country is the first in the world to have four vaccines against covid-19 approved, although only 5.7% of its population has received at least one dose of immunizer, far behind other countries.
Canada approved this Friday the use of the vaccine against covid-19 developed by Johnson & Johnson, the fourth authorized in that country – along with those of Pfizer, Moderna and AstraZeneca – after concluding that it has efficacy rates of 66.9% and that it can be used safely in people over 18 years of age. Canada has purchased a total of 10 million doses of the vaccine produced by the pharmaceutical company Janseen, a subsidiary of Johnson & Johnson. In announcing the approval, Dr. Supriya Sharma, Medical Director of the Canadian Ministry of Health, said today that after evaluating the data, they determined that “there is a large body of evidence that shows that the benefits of this vaccine outweigh the risks.”
Supriya also highlighted that Canada is the first country in the world to approve the use of four covid-19 vaccines.
Despite this, only 5.75% of the Canadian population has received at least one dose of the vaccines, which places the North American country in 42nd place in the world ranking, far behind countries such as Spain, Poland. , Turkey, Chile or the United States.
A poll released today indicates that a growing number of Canadians are frustrated with the slowness with which the government of Canadian Prime Minister Justin Trudeau is vaccinating the population. According to the survey carried out for the newspaper “National Post”, 57% of those interviewed indicated that Trudeau is doing a “bad job” in the distribution of vaccines.
Unlike the other vaccines approved for use in Canada, the Johnson & Johnson vaccine requires only one dose and can be stored for long periods in temperatures between 2 and 8 degrees Celsius, making it easy to distribute.
Johnson & Johnson’s vaccine, like AstraZeneca’s, uses a harmless virus, in this case a modified adenovirus, to elicit the immune system response. Although the Canadian health authorities have estimated the effectiveness of the Johnson & Johnson vaccine at 66.9%, the United States indicated at the end of February, when it approved its use in the country, that the drug reduces the severity of the disease by 85 % and prevents hospitalizations and deaths by 100%.
