Johnson & Johnson becomes the latest COVID-19 vaccine provider to be added to Canada’s approved list for authorized use
TDS News – On January 29, 2021, Johnson & Johnson announced topline efficacy and safety data from its Phase 3 clinical trial, demonstrating that the investigational single-dose COVID-19 vaccine in development at its Janssen Pharmaceutical Companies met all primary and key secondary endpoints. The topline safety and efficacy data are based on 43,783 participants accruing 468 symptomatic cases of COVID-19.
The Phase 3 study is designed to evaluate the efficacy and safety of the Janssen COVID-19 vaccine candidate in protecting moderate to severe COVID-19, with co-primary endpoints of 14 days and 28 days following vaccination. Among all participants from different geographies and including those infected with an emerging viral variant, Janssen’s COVID-19 vaccine candidate was 66% effective overall in preventing moderate to severe COVID-19, 28 days after vaccination.
The onset of protection was observed as early as day 14. The level of protection against moderate to severe COVID-19 infection was 72% in the United States, 66% in Latin America and 57% in South Africa, 28 days post-vaccination.
“Our goal all along has been to create a simple, effective solution for the largest number of people possible, and to have maximum impact to help end the pandemic,” said Alex Gorsky, Chairman Chief Executive Officer, Johnson & Johnson.
Today, Health Canada approved the Johnson & Johnson’s single shot vaccine for emergency authorization of use. Janssen Pharmaceutical Companies of Johnson & Johnson, to prevent COVID-19 in individuals 18 years of age and older.

If authorized, Janssen’s single-dose vaccine candidate is estimated to remain stable for two years at -20°C (-4°F), at least three months of which can be at temperatures of 2-8°C (36°F–46°F). The Company will ship the vaccine using the same cold chain technologies it uses today to transport other innovative medicines.
