Two Pfizer, AstraZeneca doses work against Delta variant: study – Al Jazeera English

Two doses of Pfizer shot 88 percent effective at preventing the Delta variant while two doses of AstraZeneca are 67 percent effective.

Two doses of Pfizer or AstraZeneca’s COVID-19 vaccine are nearly as effective against the highly transmissible Delta coronavirus variant as they are against the previously dominant Alpha variant, according to a new study.

Research published in the New England Journal of Medicine on Wednesday showed the vaccines were highly effective against the Delta variant, now the dominant strain worldwide, provided a person had received two shots.

The study confirms headline findings given by Public Health England (PHE) in May about the efficacy of COVID-19 vaccines made by Pfizer-BioNTech and Oxford-AstraZeneca based on real-world data.

Wednesday’s study found that Pfizer was 88 percent effective at preventing symptomatic disease from the Delta variant with both doses, compared with 93.7 percent against the Alpha variant, broadly the same as previously reported.

Two shots of AstraZeneca vaccine were 67 percent effective against the Delta variant, up from 60 percent originally reported, and 74.5 percent effective against the Alpha variant, compared with an original estimate of 66 percent effectiveness.

“Only modest differences in vaccine effectiveness were noted with the Delta variant as compared with the Alpha variant after the receipt of two vaccine doses,” Public Health England researchers wrote.

Data from Israel has estimated that Pfizer’s shot is less effective against symptomatic disease, although protection against severe disease remains high.

PHE had previously said that the first dose of either vaccine was approximately 33 percent effective against symptomatic disease from the Delta variant.

Other vaccines also useful

The full study published on Wednesday found that one dose of Pfizer’s shot was 36 percent effective and one dose of AstraZeneca’s vaccine was about 30 percent effective.

“Our finding of reduced effectiveness after the first dose would support efforts to maximise vaccine uptake with two doses among vulnerable groups in the context of circulation of the Delta variant,” the authors of the study said.

Recently, researchers from Beth Israel Deaconess Medical Center in the US city of Boston also said that in a laboratory setting, the antibody response from the one-dose Johnson & Johnson vaccine worked well against Delta and that immune response lasted for about eight months.

In June, makers of Russia’s Sputnik vaccine also said that it was about 90 percent effective against the highly contagious Delta variant.

The shot, which Russia has actively marketed abroad, was previously found by researchers to be almost 92 percent effective against the original strain of coronavirus.

Denis Logunov, the deputy director of Moscow’s Gamaleya Institute which developed Sputnik, said the Delta variant efficacy figure was calculated based on digital medical and vaccine records, the Russian state-owned RIA news agency reported.

The Sputnik vaccine, however, has raised some controversy as it was introduced to the public even before a full trial was completed. It is still awaiting approval from the World Health Organization.

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.”

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.
