Likewise, according to studies, Canada decided to extend the time between doses because in this way it could inoculate more people in less time, thus reducing the number of deaths from the virus, when compared to the second dose within three weeks.
“These new findings are emerging that allow us to know that in addition to having fewer cases, people are getting better protection against disease through Covid-19,” Arigosses said.
