Health Canada approves extracting six doses from Pfizer COVID-19 vaccine vials – CTV News

Published

 on


OTTAWA —
Health Canada has issued a label change authorization for the Pfizer-BioNTech COVID-19 vaccine, allowing administrators to draw one more dose from each vial than previously advised.

That means that going forward Canadian health-care professionals who are giving the shots will be able to extract six rather than five doses per vial, an update from what was authorized when the vaccine was first given the green light in December 2020.

This comes after a scientific review done by the agency of data submitted by Pfizer, demonstrating that six doses could safely and accurately be extracted from each vial.

Health Canada’s concern, in part, was based on a requirement to have a certain amount of “overfill” in each vial to ensure that there is enough vaccine to sufficiently draw up the accurate amount to yield the expected doses. The regulator’s review found that an “acceptable” amount remains in the vials once six doses are extracted.

“In order to extract a sixth dose reliably and consistently, a specialized syringe should be used. A low dead-volume syringe is designed to have a lower volume of liquid that stays in the hub of the syringe after the vaccine is administered. This minimizes the loss of vaccine volume per vaccination,” said Health Canada Senior Medical Adviser Dr. Supriya Sharma at a briefing on Tuesday.

Low-dead volume syringes are designed to have less liquid remaining in the hub of the syringe after the vaccine is administered.

The government says that while this new guidance comes into effect immediately, this week’s shipments will remain calculated at five doses per vial, but going forward the shipment allocations across Canada will be altered to reflect that there are six doses contained within each vial sent.

“This week, tens of thousands of Pfizer vaccine doses will be delivered to Canada. This is good news for so many people who will get a dose,” said Prime Minister Justin Trudeau at his Rideau Cottage address.

Conservative Leader Erin O’Toole is critical of the decision, saying it’s “mandating that the provinces do more with less.”

“The Liberals must also be clear with Canadians about whether Pfizer will replace any lost doses if the provinces are unable to extract the sixth dose,” he said in a statement.

Canada has a contract with Pfizer to receive 40 million doses of the vaccine, four million of which are to be delivered by the end of March. After weeks of shortages, next week’s shipment and those in the weeks ahead are set to increase considerably.

By counting the sixth dose what was set to be a shipment of approximately 335,000 doses is now being considered a shipment of around 400,000 shots. Similarly, the delivery coming in the last week of February will now include approximately 475,000 doses, rather than the 395,000 doses announced last week.

“While there is a change in doses contained in each vial, the country’s overall allotment from the manufacturer remains the same,” Maj.-Gen. Dany Fortin said Tuesday.

Fortin said that there are enough low-dead volume syringes in stock to continue Canada’s vaccine rollout under this new guidance, and more have been ordered and will continue to arrive over the next few months.

The goal is that with consistent use of these kinds of syringes, the instances in which health professionals are not reliably able to draw up six full doses will be lessened.

“We will continue to monitor it,” Sharma said, noting she has “anecdotally” heard of instances in which up to seven doses are able to be extracted from Pfizer vials.

American and European health authorities have already allowed the extraction of six Pfizer doses per vial.

The pharmaceutical giant is required to assist in Canada’s rollout of this change, including informing Health Canada quarterly of any issues reported from vaccine sites having issues extracting a sixth dose.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
