AstraZeneca PLC said Friday that real-world data coming from
Canada suggest that its Covid-19 vaccine is effective against
hospitalization or death from disease caused by virus variants
after just one dose.
According to study results from the Canadian Immunization
Research Network, Public Health Agency of Canada and the Canadian
Institutes of Health Research, one dose of AstraZeneca's vaccine is
82% effective at preventing hospitalization or death caused by the
coronavirus's Beta and Gamma variants. The same dose is also seen
as effective at preventing hospitalizations and deaths from the
virus's Delta variant, with 87% effectiveness against
hospitalizations and 90% effectiveness in preventing death, the
company said.
Study results were published as a pre-print, meaning they
haven't yet been peer-reviewed.
