VANCOUVER (NEWS 1130) — According to the BC Centre for Disease Control the first dose of the COVID vaccine is proven to be 80 percent successful.

Doctor Danuta Skowronski is the lead on the latest research, and says the vaccine immediately tackles the influenza and respiratory symptoms of COVID-19.

“These findings, based on surveillance data, are very promising and reinforce the substantial benefit provided by the first dose of the mRNA COVID-19 vaccine in these priority populations,” Skowronski said in a release.

Research was done from a sampling of high priority groups in the vaccine rollout including front line health care workers and long term care residents.

Both groups reported a significant drop in confirmed cases 14 days after getting the first vaccine including fewer hospitalizations and deaths of those living in long term care.

Findings show two weeks after just one dose is given, there is still an 80 per cent effectiveness compared to the risk of getting COVID-19 in the first ten days after getting the jab.

This means even with just one dose, early findings suggest eight out of 10 cases of COVID-19 can be prevented.

Both groups started getting the vaccinations in December 2020.

Researchers say the early results are encouraging especially given 60 per cent of COVID related deaths in B.C. have been in residents of long term care.
