VICTORIA, B.C. – British Columbia is moving into phase two of its immunization plan today with plans for more than 400,000 people to be vaccinated by early April.

Health authorities are reaching out to people eligible to receive their first vaccine from March 1st to 15th. In that category are seniors and high-risk people living in independent living homes, supportive housing and long-term home support clients and staff, and other priority populations, including healthcare workers.

Starting March 15th, immunizations will begin for seniors born in or before 1931 and Indigenous peoples born in or before 1956. The call centre will start booking appointments on March 8th.

Both phases one and two are prioritized for high-risk populations, while phases three and four are for the general population.

According to the B.C. government, both the Pfizer and Moderna vaccines have proven 90 per cent effective for phase one populations, including long-term care facility residents.

Growing evidence suggests even a single dose of the vaccine provides strong protection, meaning there is a possibility to extend the time between first and second doses.
