Nova Scotia's top doctor is defending the province's age-based COVID-19 vaccine strategy.
His comments come as the province's COVID-19 cases continue to climb, mainly in Central Zone, which includes Halifax.
During Monday's COVID-19 briefing, Dr. Robert Strang was asked if the province would consider changing its vaccine rollout to help address outbreaks in HRM.
The chief medical officer of health said vaccines are not what's used to control an immediate outbreak.
"You use all the other public health restrictions. Somebody who's vaccinated today takes at least two weeks for them to develop immunity," said Strang. "What we need to do to compliment the restrictions to control an immediate outbreak is to build the level of immunity in our population as quickly as possible."
Strang says the province is six weeks away from every eligible adult to be able to book an appointment for a COVID-19 vaccine.
He says switching the vaccine program at this stage would slow down the rollout and delay the province's goal of reaching population immunity.
As of Monday, the province's vaccine program expanded to allow people age 50-54 to book appointments for the Pfizer or Moderna COVID-19 vaccines.
People between the ages of 40 and 64 can also book appointments for the AstraZeneca vaccine.
