Alberta is following guidance from a national vaccine advisory panel and increasing the time between COVID-19 doses.

Dr. Deena Hinshaw, chief medical officer of health, says the greater lag time will allow more Albertans to be effectively vaccinated sooner.

The National Advisory Committee on Immunization has suggested first and second doses can be to up to four months apart if supplies are limited.

The decision was made based on emerging studies in places including Quebec, the United Kingdom and Israel that show eve one dose of the vaccine is 80 per cent — or more — effective.

When vaccines were first available late last year, manufacturers Pfizer-BioNTech and Moderna recommended two shots spaced three to six weeks apart.

Hinshaw says Alberta will still be delivering the second booster, but will delay that starting March 10 to get more people their first vaccination.
