Health Canada approves updated Moderna vaccine for Omicron variant – CBC News

Published

 on


Health Canada has formally approved Moderna’s updated COVID-19 vaccine targeting the Omicron variant.

The vaccine, which has been approved for use in adults 18 and older, will become the first COVID-19 vaccine available in Canada that targets Omicron in addition to the original strain of the coronavirus.

In a decision summary made public Thursday, Health Canada said the new vaccine shows “significantly higher responses” to the Omicron BA.1 virus in comparison to Moderna’s original coronavirus vaccine, officially branded as Spikevax.

While the updated vaccine was developed to target the Omicron BA.1 variant, Health Canada says clinical trials suggest the new vaccine still elicits a “stronger immune response” against the more recent mutations of Omicron — BA.4 and BA.5 — which are now dominant.

“Results of exploratory analyses suggest that a second booster with Spikevax Bivalent would provide a superior neutralizing antibody response against BA.4/5 compared to a second booster with Spikevax Original,” reads a portion of the decision.

Health Canada also reports that “no new safety concerns have been identified in studies when compared to the currently approved Spikevax mRNA vaccine.”

The National Advisory Committee on Immunization recommends that the updated vaccine be offered to adults who are recommended to receive a fall booster dose.

NACI says adolescents between 12 and 17 with “moderately to severely immunocompromising conditions” and those who have elevated social risk factors could also be offered the vaccine.

Health Canada’s Chief Medical Adviser Dr. Supriya Sharma says Moderna’s new bivalent vaccine will target both the old variant of COVID-19 as well as Omicron, the more recent one. It has been approved for use in Canadians 18 years and older.

The updated vaccine is a combination of two strains, also known as “bivalent” shots. It contains both the original vaccine formulation and protection against the original Omicron variant BA.1.

The new Moderna shot will be delivered in 50 microgram doses. Half of its contents target the original coronavirus strain while the other half target Omicron.

An initial shipment of 780,000 doses of the updated vaccine is set to arrive in Canada on Friday, Health Minister Jean-Yves Duclos said. An additional 10.5 million doses will be delivered by the end of September.

Deliveries to the provinces and territories, which oversee the administration of vaccines, are set to begin next week.

Duclos urged Canadians to sign up for booster shots quickly as summer comes to an end.

“This fall will be challenging, with the return of the flu and other respiratory diseases and people moving indoors,” Duclos told a news conference on Thursday afternoon.

Vaccines for newer Omicron strains may be coming

Both Moderna and Pfizer have developed even newer bivalent vaccines targeting the Omicron BA.4 and BA.5 strains, but the companies have not yet submitted those products for approval by Health Canada.

Njoo said that in choosing to approve Moderna’s BA.1-focused vaccine, the government considered the tools it has now “versus what might potentially happen in the future.”

“At the end of the day, we’re very comfortable with the fact that we have a good bivalent vaccine,” Njoo added.

The U.S. Food and Drug Administration announced Wednesday its approval of bivalent vaccines by Pfizer and Moderna that specifically target the more recent Omicron BA.4 and BA.5 strains.

Dr. Supriya Sharma, the chief medical adviser with Health Canada, said the agency expects to receive a submission from Pfizer as soon as next week for a bivalent vaccine targeting BA.4 and BA.5.

A new submission by Moderna for BA.4 and BA.5 is also expected within the next two weeks, Sharma said.

A spokesperson for Pfizer Canada told CBC News Wednesday that its submission to Health Canada for a BA.1-targeted bivalent vaccine is still under review and approval has not yet been granted.

Infectious diseases physician Dr. Lisa Barrett is encouraged by approval of the new bivalent vaccine targeting Omicron BA.1. She says holding out for the next, more updated vaccine would be risky.

Angela Rasmussen, a virologist with the University of Saskatchewan’s Vaccine and Infectious Disease Organization, said the vaccine’s approval is an important development in Canada’s fight against COVID-19 —  even though the shot was developed for a strain that is no longer circulating widely.

“I do think it’s really important now for people to know that the BA.1 vaccine is still going to really improve immunity against the variants that are circulating,” Rasmussen told CBC News.

Another expert said Canadians should not wait for the perfect and most up-to-date vaccine, since they’ll likely need repeated COVID-19 immunizations in the future.

“That protection will not last. This will not be the last vaccine you get. So prepare, until we have vaccines that are better, to be vaccinated probably every six months,” said Dawn Bowdish, an immunologist at McMaster University.

Netflix’s subscriber growth slows as gains from password-sharing crackdown subside

Published

 on

 

Netflix on Thursday reported that its subscriber growth slowed dramatically during the summer, a sign the huge gains from the video-streaming service’s crackdown on freeloading viewers is tapering off.

The 5.1 million subscribers that Netflix added during the July-September period represented a 42% decline from the total gained during the same time last year. Even so, the company’s revenue and profit rose at a faster pace than analysts had projected, according to FactSet Research.

Netflix ended September with 282.7 million worldwide subscribers — far more than any other streaming service.

The Los Gatos, California, company earned $2.36 billion, or $5.40 per share, a 41% increase from the same time last year. Revenue climbed 15% from a year ago to $9.82 billion. Netflix management predicted the company’s revenue will rise at the same 15% year-over-year pace during the October-December period, slightly than better than analysts have been expecting.

The strong financial performance in the past quarter coupled with the upbeat forecast eclipsed any worries about slowing subscriber growth. Netflix’s stock price surged nearly 4% in extended trading after the numbers came out, building upon a more than 40% increase in the company’s shares so far this year.

The past quarter’s subscriber gains were the lowest posted in any three-month period since the beginning of last year. That drop-off indicates Netflix is shifting to a new phase after reaping the benefits from a ban on the once-rampant practice of sharing account passwords that enabled an estimated 100 million people watch its popular service without paying for it.

The crackdown, triggered by a rare loss of subscribers coming out of the pandemic in 2022, helped Netflix add 57 million subscribers from June 2022 through this June — an average of more than 7 million per quarter, while many of its industry rivals have been struggling as households curbed their discretionary spending.

Netflix’s gains also were propelled by a low-priced version of its service that included commercials for the first time in its history. The company still is only getting a small fraction of its revenue from the 2-year-old advertising push, but Netflix is intensifying its focus on that segment of its business to help boost its profits.

In a letter to shareholder, Netflix reiterated previous cautionary notes about its expansion into advertising, though the low-priced option including commercials has become its fastest growing segment.

“We have much more work to do improving our offering for advertisers, which will be a priority over the next few years,” Netflix management wrote in the letter.

As part of its evolution, Netflix has been increasingly supplementing its lineup of scripted TV series and movies with live programming, such as a Labor Day spectacle featuring renowned glutton Joey Chestnut setting a world record for gorging on hot dogs in a showdown with his longtime nemesis Takeru Kobayashi.

Netflix will be trying to attract more viewer during the current quarter with a Nov. 15 fight pitting former heavyweight champion Mike Tyson against Jake Paul, a YouTube sensation turned boxer, and two National Football League games on Christmas Day.
