With Health Canada giving the green light for the Johnson & Johnson COVID-19 vaccine, Canadians can look forward to being inoculated earlier than September.

Based on studies in about 43,000 participants, the single dose Janssen COVID-19 vaccine was 66% effective in preventing symptomatic COVID-19 disease. “Immunity develops over time.” You won’t develop significant protection against COVID-19 for at least 2 weeks,” the health authority said on its website.

Like AstraZeneca, the Johnson & Johnson product also uses vector virus technology but offers almost the same level of efficacy in just one dose. Health Canada says, no major safety concerns have been identified in the data reviewed by it. Chief Medical Advisor, Dr Supriya Sharma adds that it is also easier to transport, store and administer.

With four vaccines now approved, timelines for inoculating the general public will see a significant change. The first shipments of Johnson & Johnson’s Janssen COVID-19 vaccine are expected to arrive sometime in April.
