VICTORIA, B.C. – The Province announced recipients of two doses of the AstraZeneca COVID-19 vaccine will be invited to schedule their booster shot six months after their previous dose.

Dr. Bonnie Henry said on Monday that this announcement comes after more data has come in regarding vaccine efficacy.

“Individuals who receive two doses of AstraZeneca have had waning protection from infection. Thankfully, they still have very strong protection for serious illness, but lower protection against infection,” said Dr. Henry. “And as a result, people who receive two doses of AstraZeneca will be receiving invitations for their booster dose at six months.”

Booster doses will be with an mRNA vaccine, a combination that Henry says is long-lasting.

“Here in B.C., most people have good, strong protection from any combination of vaccines that they’ve received. And that protection is lasting out to 7, 8 months,” said Henry of who would be eligible for the booster shot.

“So the vast majority of people are not eligible right now for a booster dose, but we want them to be prepared for the fact that it is looking more and more like a booster dose at some point, at maybe 6 to 8 months, is something that is going to give us longer-lasting, durable protection.”
