“We’re actual time vaccine effectiveness,” stated Noni MacDonald, a professor of pediatric infectious illnesses, who makes a speciality of vaccine analysis.
“Total, I used to be very impressed by what the numbers already confirmed us. These vaccines are actually working.”
Dr. Robert Strang, the province’s chief medical officer of well being, defined the breakthrough case knowledge on the COVID-19 briefing on Friday.
Between March 15 and June 1, there have been 3,902 COVID-19 circumstances. Of these:
3,691 (94.6 per cent) had been unvaccinated. 187 (4.8 per cent) had been partially vaccinated. 24 (0.6 per cent) had been totally vaccinated.
Of the 242 people who had been hospitalized:
