Johnson & Johnson is a one dose vaccine but has not been approved in Canada yet.

Earlier Wednesday, Trudeau said any change in public health guidance regarding the timing of the two doses could affect the speed of Canada's vaccine rollout, as could the approval of more vaccines like Johnson and Johnson.

However it's not expected that any will arrive in the Canada until at least April.

Canada's drug regulator has approved Johnson & Johnson's COVID-19 vaccine, the fourth such shot to be given the green light, the government said on Friday, amid frustration over the slow start to the country's inoculation program.

"Extending the dose interval to four months allows NACI to create opportunities for protection of the entire adult population within a short timeframe", NACI said.

The United States Conference of Catholic Bishops released a statement this week about the recently approved COVID-19 vaccine from Johnson & Johnson.

She said experts are basing vaccine decisions on evidence as it is presented.

The committee's recommendation came hours after Newfoundland and Labrador said it will extend the interval between the first and second doses to four months, and days after health officials in British Columbia announced they were doing so.

Effectiveness against variants of concern will also be monitored closely, and recommendations may need to be revised, it said, adding there is now no evidence that a longer interval will affect the emergence of the variants.

Production problems slowed initial deliveries in the United States.

"It requires just conventional refrigeration and it's a one-and-done shot", Bogoch said.

Health Canada approved the Pfizer-BioNTech and Moderna Inc vaccines in December, and AstraZeneca's vaccine in February.

"Outlining steps to measure protection by looking at the antibodies in the blood following vaccination and eliminating the need for lengthy clinical studies, this guidance will lead to important outcomes: Safe vaccines tailored to emerging variants, manufactured and made ready for use in significantly reduced time", Deputy Chief Public Health Officer Dr. Howard Njoo said Thursday.

And Chagla stressed that ultimately, this one-dose option could offer a "real solution" that helps countries like Canada tackle this year-long pandemic and alleviate the current burden on the health-care system from a virus that's still widespread. "Those who, however, for reasons of conscience, refuse vaccines produced with cell lines from aborted fetuses, must do their utmost to avoid, by other prophylactic means and appropriate behavior, becoming vehicles for the transmission of the infectious agent", he said.

Manitoba said it plans to target those between the ages of 50 and 64 who have high-risk underlying conditions. The province said it expects to receive its first shipment of the AstraZeneca shot by mid-month.

Other provinces, including Quebec, New Brunswick and Nova Scotia, are still mulling over the issue.

As the Associated Press explained, Johnson & Johnson's COVID-19 vaccine is made using a harmless cold virus, called an adenovirus, the same technology it used to produce a successful Ebola vaccine.

Canada also received its first doses of AstraZeneca's vaccine this week, after approval was given to two versions of it last week.

Johnson & Johnson has a contract to supply the USA federal government with 100 million doses of their vaccine by the end of June.
