Ontario reports 2,759 new COVID-19 cases, lowest positivity rate in nearly six weeks
Ontario is reporting a slight increase in the number of new COVID-19 infections with more than 2,700 cases confirmed today but the province’s test positivity rate has now dropped to its lowest level in nearly six weeks.
Provincial health officials logged 2,759 new infections today, up from the 2,320 cases confirmed on Wednesday and 2,073 infections recorded on Tuesday.
Mixing COVID-19 vaccines appears safe — but no data on whether it works, U.K. study says
New preliminary data suggests that mixing Pfizer-BioNtech and AstraZeneca COVID-19 vaccines is safe, but it’s still too soon to tell whether combining doses will provide protection against the virus.
The early results from a University of Oxford study found that mixing the two vaccines may increase the frequency of mild to moderate side effects. But the symptoms, referred to in the study as “reactogenicity,” were short-lived — lasting no longer than a few days — and there were no hospitalizations or other safety concerns.
