A Canadian government epidemiologist in charge of reviewing COVID-19 scientific literature testified in court that there is little information available on the impacts of vaccination on in-flight transmission of the virus.
“There are not many studies that look at vaccination status, most of the research that’s been done occurred prior to widespread vaccination,” said Dr. Lisa Waddell of the Emerging Sciences Group at the Public Health Agency of Canada (PHAC).
