With the Delta variant dominant across Canada and cold weather approaching, scientists & health authorities have turned their attention to the question of who may need a third dose of the COVID-19 vaccine – and when.

Here's a closer look at the science:

tgam.ca/covid-19-boost…
Who in Canada is eligible for a third dose?

NACI recommends immunocompromised people 12 and older – who have not yet been immunized – should receive 3 doses of a mRNA vaccine. Those in this group who have been vaccinated should be offered an third dose.

tgam.ca/covid-19-boost…
Alberta, Ontario and Quebec have already been offering additional doses – not only to the immunocompromised but also to people travelling to countries that do not currently recognize their primary vaccine series.

tgam.ca/covid-19-boost…
Which countries are currently giving third doses?

Israel was the first country to broadly offer third shots. A number of European countries have followed suit, including Hungary, France, Germany, Belgium, Austria, Ireland and Sweden.

tgam.ca/covid-19-boost…
What does science say about the need for a third dose?

While experts says that booster shots may eventually be required, they say it’s too soon to pursue – while it’s clear the world would benefit far more from getting those doses to the unvaccinated.

tgam.ca/covid-19-boost…
How well are vaccines holding up so far?

Data continues to show the benefits of vaccination now that the Delta variant is the principal driver of the pandemic in North America. Vaccines are still very effective against severe disease and death.

tgam.ca/covid-19-boost…
What are the ethical considerations?

WHO's director-general has called for a moratorium on booster shots until the end of the year, saying that while some at-risk populations may require them, healthy vaccinated people should not be receiving boosters.

tgam.ca/covid-19-boost…
What determines when boosters will be needed?

If the immunity afforded by vaccines indeed begins to wane after several months, then a booster shot may become advisable for vaccinated Canadians by that time.

Bottom line: The jury is still out.

British Prime Minister Boris Johnson is ditching vaccine passports, mandatory face mask rules and work-from-home regulations – and will instead rely mainly on vaccinations to get the country through the winter months.

tgam.ca/2XijF6c
On Tuesday, Mr. Johnson outlined the government’s pandemic strategy for England.

Governments in Scotland, Wales and Northern Ireland, which run their own health care systems, are expected to largely follow suit.

The strategy centred largely on expanding vaccinations to younger teenagers and launching a booster shot program for front-line health care staff and people over the age of 50.

Metro Vancouver is the eviction capital of Canada, according to a new report.

tgam.ca/vancouver-evic…
A @UBC study shows that 10.5% of renter households in Metro Vancouver experienced an eviction as the reason for their last move.

That compares to 5.8% in Toronto and 4.2% in Montreal.

tgam.ca/vancouver-evic…
The province of British Columbia as a whole has an equally bleak rate of eviction, at 10.6%, again, by a wide margin.

The next highest rate of eviction was on Prince Edward Island, at 6.8%.

Two of Netflix’s most-prized 2021 festival movies have leaked online after debuting as part of the at-home digital offerings of the Toronto International Film Festival.

#TIFF21

tgam.ca/tiff-netflix-l…
Jane Campion’s drama “The Power of the Dog,” starring Benedict Cumberbatch, and the Antoine Fuqua thriller “The Guilty,” led by Jake Gyllenhaal, both appeared on pirate websites as of early Monday.

tgam.ca/tiff-netflix-l…
It was not immediately clear if TIFF showings were the source of the pirated copies or if they came from elsewhere.

However, both movies premiered as part of TIFF’s hybrid festival model with screenings in theatres as well as virtually in homes.

Conservative Leader @erinotoole unleashed an attack on @JustinTrudeau on Monday, portraying the Liberal Leader as entitled and selfish.

Trudeau, meanwhile, accused O’Toole and @CPC_HQ of being beholden to the gun lobby and the anti-vaccination movement.

tgam.ca/3AbKOWw
The attacks from both leaders marked a turn to negative campaigning, with just one week remaining before the Sept. 20 vote. #Elxn44

theglobeandmail.com/politics/artic…
O’Toole spent the first 18 minutes of a news conference reading from prepared remarks that referenced the Liberal Leader’s former “partying” days, the SNC-Lavalin scandal and Trudeau’s disputes with prominent women in his caucus.
