A Phase 1 trial of a prospective COVID-19 vaccine that will soon be tested on Canadians has found it to be safe and also prompted an immune response, but researchers caution they are far from knowing whether or not it could actually protect people from the virus.

An early trial of a prospective COVID-19 vaccine that will soon be tested on Canadians has found it to be safe and also prompted an immune response.
A study published Friday in the Lancet journal said the formulation from China’s CanSino Biologics Inc. needs more trials to determine whether it can actually protect against SARS-CoV-2, the virus that causes COVID-19.
But it said early trials involving 108 adults in Wuhan produced neutralizing antibodies and a response in T-cells, which protect the body from pathogens, after 28 days. The most common side effects — d
