Alberta extending second-dose immunization timelines

Mar 3, 2021 | 4:15 PM

Alberta will join other provinces in adopting the National Advisory Committee on Immunization recommendation to extend the period between first and second doses of COVID-19 vaccine.

Dr. Deena Hinshaw said that starting March 10, anyone who books a first dose appointment will have their second dose timeline extended to up to four months.

The goal, she said, is to provide “first doses to all Albertans as soon as possible.”

Those who have second-dose appointments already booked will have theirs go ahead as scheduled. Anyone who books their appointment before March 10 will still be able to book a second appointment within their 42-day window.

Those who book on or after March 10 will only be able to book a first appointment. Later they will receive a reminder to book their second appointment.

“This change will significantly increase how quickly we can offer Albertans the protection of their first dose,” the chief medical officer of health said. “The more people that we can offer this protection to in the coming weeks and months, the more effective we will be at stopping spread.”

Hinshaw said evidence on COVID-19 is constantly evolving and it is critical the most-up-to-date information is used as the approach to fighting the virus is refined.

She said research from other jurisdictions has shown one dose of the Moderna or Pfizer vaccine offers a huge boost in immunity. Canadian data indicates 80 per cent protection against infection after the first dose.

Second doses in the 16-week window is best for long-lasting protection.

Hinshaw said first shipments of the Astra Zeneca vaccine approved last week by Health Canada are expected to arrive in Alberta next week. The Astra Zeneca vaccine will give Alberta three safe, effective vaccines, Hinshaw said.

She did not have details on how many doses would arrive and an update on distribution will be provided as soon as possible.

“What’s clear is that all three of these vaccines reduce the risk of getting COVID-19 and prevent serious outcomes including hospitalization and death.”
