Most B.C. COVID cases are in 20- to 40-year-olds with one or fewer doses: top doctor

VANCOUVER — British Columbia’s top doctor says the surge in COVID-19 cases is fuelled by those between the ages of 20 and 40 who are unvaccinated or have only had one dose. 

The latest daily case count reached 342 on Wednesday, a figure not seen since late May, but Dr. Bonnie Henry says clusters of infections were expected. 

Henry says the key is that health officials aren’t seeing widespread transmission to at-risk groups such as seniors because they have a high rate of immunization.

She says pandemic modelling shows the Delta variant is more transmissible, which means immunization rates must go up, and even a small increase in vaccinations makes a difference.
