But it remains effective at keeping people out of hospital

The effectiveness of the Pfizer vaccine in preventing infection from COVID-19 wanes after six months, according to a study published Tuesday in The Lancet.

But the study also shows full vaccination prevents people from getting so sick they have to be admitted to a hospital.

“Our results show high effectiveness of (Pfizer-BioNTech) against hospital admissions up until 6 months after being fully vaccinated,” the authors wrote. “Effectiveness against SARS-CoV-2 infections waned during the 6 months of this study.”

Doctors tracked 3.5 million people vaccinated with Pfizer-BioNTech. They found, after a second shot, the vaccine was 73% effective in preventing infection.

That fell to 47% after five months.

The vaccine was 93% effective at preventing hospital admissions and remained at that level.

“Is there waning over time? The answer is probably yes. There probably is some degree of vaccine effectiveness that wanes with time,” said Dr. Isaac Bogoch, of the University Health Network. “This study probably over-estimates the degree of how much the vaccine wanes.”

When it comes to tackling the dominant Delta variant in Canada, the study found Pfizer was 93% effective at first.

After four months, that fell to 53%.

The medical community has been discussing whether booster shots are necessary.

The Lancet study touched on that, saying: “Our findings underscore the importance of monitoring vaccine effectiveness over time and suggest that booster doses might eventually be needed to restore the high levels of protection observed early in the vaccination program.”

Bogoch said Canada does not need a broad booster campaign right now.

“There might be a point where we all need a third dose, but that time is not now,” he said. “It’s currently only select populations that would benefit from a third dose.”

He added that with Ontario 82% fully vaccinated and 86% with at least a single dose, the province is in a much better position than some to weather the fourth wave.

Some countries have already started administering booster shots.

The study’s authors admitted their survey has limitations because it did not take into account post-vaccination behaviours such as whether people continued to wear masks and maintained social distancing when around others.

  2. Ontario now recommending against Moderna vaccine for men 18-24 years old


  3. More than 100 Ontario youth sent to hospital for vaccine-related heart problems: Report

“This is what’s called an observational study,” Bogoch said. “It is not a randomized control trial.”

Roots sees room for expansion in activewear, reports $5.2M Q2 loss and sales drop

Published

 on

 

TORONTO – Roots Corp. may have built its brand on all things comfy and cosy, but its CEO says activewear is now “really becoming a core part” of the brand.

The category, which at Roots spans leggings, tracksuits, sports bras and bike shorts, has seen such sustained double-digit growth that Meghan Roach plans to make it a key part of the business’ future.

“It’s an area … you will see us continue to expand upon,” she told analysts on a Friday call.

The Toronto-based retailer’s push into activewear has taken shape over many years and included several turns as the official designer and supplier of Team Canada’s Olympic uniform.

But consumers have had plenty of choice when it comes to workout gear and other apparel suited to their sporting needs. On top of the slew of athletic brands like Nike and Adidas, shoppers have also gravitated toward Lululemon Athletica Inc., Alo and Vuori, ramping up competition in the activewear category.

Roach feels Roots’ toehold in the category stems from the fit, feel and following its merchandise has cultivated.

“Our product really resonates with (shoppers) because you can wear it through multiple different use cases and occasions,” she said.

“We’ve been seeing customers come back again and again for some of these core products in our activewear collection.”

Her remarks came the same day as Roots revealed it lost $5.2 million in its latest quarter compared with a loss of $5.3 million in the same quarter last year.

The company said the second-quarter loss amounted to 13 cents per diluted share for the quarter ended Aug. 3, the same as a year earlier.

In presenting the results, Roach reminded analysts that the first half of the year is usually “seasonally small,” representing just 30 per cent of the company’s annual sales.

Sales for the second quarter totalled $47.7 million, down from $49.4 million in the same quarter last year.

The move lower came as direct-to-consumer sales amounted to $36.4 million, down from $37.1 million a year earlier, as comparable sales edged down 0.2 per cent.

The numbers reflect the fact that Roots continued to grapple with inventory challenges in the company’s Cooper fleece line that first cropped up in its previous quarter.

Roots recently began to use artificial intelligence to assist with daily inventory replenishments and said more tools helping with allocation will go live in the next quarter.

Beyond that time period, the company intends to keep exploring AI and renovate more of its stores.

It will also re-evaluate its design ranks.

Roots announced Friday that chief product officer Karuna Scheinfeld has stepped down.

Rather than fill the role, the company plans to hire senior level design talent with international experience in the outdoor and activewear sectors who will take on tasks previously done by the chief product officer.

Talks on today over HandyDART strike affecting vulnerable people in Metro Vancouver

Published

 on

 

VANCOUVER – Mediated talks between the union representing HandyDART workers in Metro Vancouver and its employer, Transdev, are set to resume today as a strike that has stopped most services drags into a second week.

No timeline has been set for the length of the negotiations, but Joe McCann, president of the Amalgamated Transit Union Local 1724, says they are willing to stay there as long as it takes, even if talks drag on all night.

About 600 employees of the door-to-door transit service for people unable to navigate the conventional transit system have been on strike since last Tuesday, pausing service for all but essential medical trips.

Hundreds of drivers rallied outside TransLink’s head office earlier this week, calling for the transportation provider to intervene in the dispute with Transdev, which was contracted to oversee HandyDART service.

Transdev said earlier this week that it will provide a reply to the union’s latest proposal on Thursday.

A statement from the company said it “strongly believes” that their employees deserve fair wages, and that a fair contract “must balance the needs of their employees, clients and taxpayers.”

MONTREAL – Travel company Transat AT Inc. reported a loss in its latest quarter compared with a profit a year earlier as its revenue edged lower.

The parent company of Air Transat says it lost $39.9 million or $1.03 per diluted share in its quarter ended July 31.

The result compared with a profit of $57.3 million or $1.49 per diluted share a year earlier.

Revenue in what was the company’s third quarter totalled $736.2 million, down from $746.3 million in the same quarter last year.

On an adjusted basis, Transat says it lost $1.10 per share in its latest quarter compared with an adjusted profit of $1.10 per share a year earlier.

Transat chief executive Annick Guérard says demand for leisure travel remains healthy, as evidenced by higher traffic, but consumers are increasingly price conscious given the current economic uncertainty.
