Canada doesn't need vaccine boosters yet, but planning for possibility: Tam – National | – Global News



Canada isn’t ready to offer COVID-19 booster shots as there’s “not enough data” to support it quite yet, the country’s top doctor said Friday, despite countries like Israel pushing ahead with a vaccination top-up.

Dr. Theresa Tam, the chief public health officer of Canada, told reporters that even though the data is quickly “evolving,” the timing for boosters isn’t right.

“There’s not enough data to suggest that in Canada we would go into boosting as of yet,” she said. “But it is something that we’re watching very carefully.”

Tam’s comments come as Israel will begin offering a third shot of the Pfizer-BioNTech vaccine to fully vaccinated people over the age of 60. Israel decided to offer the booster due to the highly transmissible Delta variant’s spread in the country.

Neither the European Union nor the United States has approved such a strategy.

Israel’s president, Isaac Herzog, is getting a booster on Friday. It will be offered to the targeted population on Sunday.

Tam said Canada isn’t seeing many breakthrough infections in fully vaccinated people at this point, but the country is getting “operationally ready” to implement a booster if needed.

“But we’re very much attuned to the potential for a need for booster,” she said. “And we’re getting operationally ready, whether it is looking at supply, whether we’re looking at the implementation side, the provinces are looking at, well, what if we did need one? How would we implement that?”

A breakthrough infection is when someone who is fully vaccinated contracts the virus. These are expected, according to experts, as no COVID-19 vaccine is 100 per cent effective at preventing illness in vaccinated people.

Earlier this week, the government announced it had reached 66 million vaccine doses procured – enough to vaccinate every eligible Canadian. But, vaccination rates in the country have slowed.

To date, roughly 80 per cent of eligible Canadians have at least one dose of a vaccine and 65 per cent are fully vaccinated.

“But we’ve got to get those first and second doses and that’s got to be the priority,” Tam said. “But we will, of course, be updating everyone should there be a change in the advice for boosters.”

Also on Friday, officials said that Canada is likely at the start of a Delta-driven fourth wave of the pandemic due to an upward trend in cases across the country.

Most are in the unvaccinated, but if vaccine uptake doesn’t increase in younger groups, cases could eventually exceed health-care system capacity, a long-range epidemic forecast reads.

With COVID-19 and its variants continuing to spread across the globe, some pharmaceutical companies have begun exploring the possibility of booster shots to target variants or boost immunity.

On Wednesday, Pfizer released a trial update that claimed its third dose generated virus-neutralizing antibodies against the Delta variant more than five times higher in younger people and more than 11 times higher in older people than from two doses.

However, some experts are skeptical and suggest that we might not actually need it.

“I don’t think there’s good clinical evidence,” Dr. Zain Chagla, an infectious disease specialist told Global News in an earlier interview.

Chagla said people “shouldn’t necessarily worry that these two shots are going to be useless in a few years.”

“These are the shots that are going to keep people out of hospital and … from dying,” he said.

John Moore, a virologist at Weill Cornell Medicine in New York, reiterated the sentiment.

“The general feeling that it is not the right time for a third dose of the mRNA vaccines,” he said. “We’re not saying it should never happen, but now is not the time.”

Regardless, officials are keeping an open mind, including Deputy Prime Minister Chrystia Freeland.

“We are very aware of Israel’s decision. Actually yesterday, a number of ministers had a good conversation with Dr. Theresa Tam, our chief public health officer, about the Delta variant and about booster shots,” she said at a separate news conference on Friday.

“As has been the case since the beginning of this pandemic, the Canadian response is going to be guided by science and by the advice of our medical officials.”

More than half of Manitoba's 64 new COVID-19 cases unvaccinated – CTV News Winnipeg




While more than half of Manitoba’s new COVID-19 cases are among the unvaccinated, the province reported 20 breakthrough infections.

On Thursday, Manitoba public health officials reported 64 new COVID-19 cases – including 36 unvaccinated cases and eight partially vaccinated cases. Twenty of the cases were among people who had been fully vaccinated.

“No vaccine is 100 per cent effective. However, people who are fully vaccinated typically have a better outcome than individuals who are not vaccinated,” a spokesperson told CTV News in an emailed statement.

“Public health continues to recommend that the best defence against COVID-19 is to get immunized.”

As of Thursday, 84 per cent of eligible Manitobans have rolled up their sleeve for at least one dose of a COVID-19 vaccine. Seventy-nine per cent of eligible Manitobans are vaccinated with two doses.

The spokesperson said while breakthrough cases can occur, the outcomes are typically not as severe as they are for non-vaccinated individuals. They said fully vaccinated people who get infected typically do not need to go to ICU.

As of Thursday, 62 people in Manitoba are in hospital with COVID-19, including 26 people who have active cases. Of those active cases, 20 are not vaccinated, four are partially vaccinated and two are fully vaccinated.

There are five people in the intensive care unit with active cases of COVID-19, all of whom are unvaccinated.

Data from the province obtained by CTV News shows there have been 728 infections and 16 deaths among the 915,200 people fully immunized in the province.

Of the 986,054 people who have been partially immunized in Manitoba, the data shows there have been 2,215 infections and 45 deaths.

The Southern Health region saw the most cases in the province on Thursday, with 23 new cases reported.

The Northern and Winnipeg health regions both reported 15 new cases. Winnipeg is sitting with a 1.2 per cent five-day test positivity rate.

The Prairie Mountain Health Region reported six new cases and the Interlake-Eastern health region reported five new cases.

The new cases bring Manitoba’s total to 59,526, including 599 active cases and 57,724 recoveries. Seven cases were removed from the total due to data corrections.

The provincial five-day test positivity rate is now 2.5 per cent.

The province also released some details of two deaths that were announced on Wednesday – both of which were linked to variants of concern. The deaths include a woman in her 70s from the Interlake-Eastern health region, linked to the Delta variant, and a man in his 80s from Winnipeg linked to an unspecified variant.

The total number of people who have died with COVID-19 sits at 1,203, including 201 deaths that have been linked to variants of concern.

In total, Manitoba has linked 18,065 cases to variants. 370 variant cases are active, and 17,494 have recovered.

Goodbye Pfizer, hello Comirnaty: top COVID-19 vaccines renamed in Canada –



It’s pronounced koh-MIHR’-nuh-tee. Never heard of it? Well, get used to it. It’s what Canada will be calling the Pfizer vaccine from now on, at least officially.

Health Canada has approved new monikers for Pfizer, Moderna and Oxford-AstraZeneca vaccines and announced the change on social media today.

The Pfizer-BioNTech vaccine has now been dubbed Comirnaty, which the company says represents a combination of the terms COVID-19, mRNA, community, and immunity.

The Moderna vaccine will go by SpikeVax and the AstraZeneca vaccine will be named Vaxzevria.

Pfizer and Moderna say the change marks the full approval of the vaccines by Health Canada, which were previously approved under an interim order that was set to expire today.

During the interim order, the vaccines didn’t go by their brand names, but now that new and more long-term data has been submitted and approved they will go by their permanent name.

“Health Canada’s approval of COMIRNATY for individuals ages 12 and older affirms the vaccine’s safety and efficacy shown in longer term data submitted to Health Canada — and hopefully that licensure may improve vaccine confidence among Canadians,” Pfizer spokesperson Christina Antoniou wrote in a statement.

It’s the first time SpikeVax, until now known as the Moderna vaccine, has been fully approved anywhere in the world, Stéphane Bancel, the company’s CEO, said in a press release Thursday.

Health Canada points out the vaccines themselves are not changing — only the names are.

Although the name change has been approved, Canada will still receive vials labelled Pfizier-BioNTech for the next several months.

The FDA approved new names in the United States earlier this summer, and the vaccines have been going by their brand names in the EU since the spring.

How concerning is the latest COVID-19 Mu variant in B.C.? – News 1130



VANCOUVER (NEWS 1130) — A new strain of the COVID-19 virus is now in the province, and it is leading to questions around potential risk.

The B.1.621 — or Mu — variant was first discovered in Colombia in January and has been found in more than 40 people in B.C. since June. The World Health Organization has now classified the strain as a “Variant of Interest.”

The case numbers are minimal compared to the highly transmissive Delta variant, which has exploded across the country, leading to more COVID-19 cases and hospitalizations.

In B.C. alone, nearly all the new cases of COVID-19 are linked to the Delta variant.

Still, there was a time when the impact of that strain was not known, prompting many to worry that the new Mu variant could be just as dangerous as Delta.

Sally Otto, a UBC zoology professor and modelling researcher, says right now, that’s not the case and there is no need to panic.

“Mu hasn’t actually been rising in frequency, it’s been kind of hovering under about two per cent frequency, relative to what we saw with Delta, which was once it got established, [there was] really rapid exponential growth,” Otto said.

“That doesn’t mean we shouldn’t pay attention to it, we absolutely should keep an eye on it. But it’s not taking off. Right now, Delta is the main player, the main variant that is the most transmissible and the most worrisome in this country,” Otto said.

Dr. Birinder Narang, co-founder of This is Our Shot campaign, agrees. “It is not showing a significant impact in B.C., we need to watch,” he wrote on social media.

The bigger concern than the variant itself, Otto says, is how slow Canada is at sharing data from mapping virus sequences to discover variants of interest present in the population.

A new report found Canada among the worst for sharing data on genome sequencing.

Canada takes three months to present collected data to the global database, compared to the United Kingdom which is able to do it in just two weeks.

The data is then studied by public health officials, scientists, and other experts around the world to examine what variants are present, and how fast they are spreading.

“There could absolutely be more variants. Now to be honest, Canada doesn’t have as much cases as there are globally so the chances are the variant of concern is going to arise somewhere else. But if a variant of concern arises in Canada, we can’t tell.”

She says the delay in information impacts making real-time decisions on public policy surrounding the virus.

“We can’t tell within Canada if there are subtypes of the Delta that are spreading faster than others, and that’s something we need to know,” she said about the mutations and which ones to pay attention to.

Otto says the disconnect of information sharing is even happening in Canada between provinces and territories.

“Here in British Columbia we are sequencing almost every single case of COVID to try and identify what exactly the genetic changes are inside the genome of the virus. But unfortunately that is not then being shared globally, and it’s not even being shared across Canada. And that means that scientists like me who aren’t inside the public health office, we can’t use our skills to look for the changes that are happening in these genomes,” she said, adding the last time B.C. updated their data was two months ago.

Despite fears, the BC Centre of Disease Control says the current vaccines protect against all variants of concern, including Delta, and because variants spread more easily, it is even more important for the majority of the population to be vaccinated.

“This helps protect people who cannot get vaccinated, including children under 12,” the BCCDC explained.
