‘On the precipice:’ COVID-19 has Canadian Blood Services worried about shortage – The Globe and Mail

Published

 on


The Canadian Press

A senior official with Canadian Blood Services is warning that Canada is facing a critical shortage if it doesn’t find a way to make up for a sharp drop in blood donations.

Dr. Isra Levy says donations dropped about 20 per cent late last week because of concerns over the COVID-19 pandemic and he’s worried about making up the difference.

“We’re right on the precipice. Because although the inventory is solid and we’re seeing some hospitals cancelling elective procedures, we know that for some blood components that we produce, the shelf life for our products is very short,” Dr. Levy said Monday.

“At any time we’re days away from having a shortage particularly of platelets and rare blood types.”

Some hospitals have cancelled elective surgeries, but there is still a constant demand as a result of trauma from accidents and for cancer patients who need regular transfusions, Dr. Levy said. He points to blood shortages being reported in other countries affected by COVID-19.

Canadian Blood Services operates a national blood inventory that allows products to be regularly shifted around the country to meet hospital and patient needs. Inventory is strong, Dr. Levy said, but the increase in donor cancellations is troubling.

“We certainly are worried we’re in that space right now. We could be days away from critical shortages.”

Dr. Levy said about 400,000 of Canada’s 37 million residents give blood on a regular basis and making up for donations from people choosing to stay home during the pandemic could prove difficult. A number of corporate blood drives have also been cancelled, which has resulted in a further strain on the supply, he said.

Dr. Levy said it is safe to visit clinics. All prospective donors are carefully screened for symptoms of illness, including mild ones. Those with any symptoms are not allowed to donate blood and are instructed not to visit.

“What we really want to encourage our donors to remember is that this is an essential service. We are places where well people congregate … not ill people,” he said.

“Our donor centres are islands of wellness within Canada’s health system.”

In addition to encouraging new donors to come forward, Canadian Blood Services is looking at extending hours at a number of clinics across the country.

Interior Health delivers nearly 800K immunization doses in 2023

Published

 on

Interior Health says it delivered nearly 800,000 immunization doses last year — a number almost equal to the region’s population.

The released figure of 784,980 comes during National Immunization Awareness Week, which runs April 22-30.

The health care organization, which serves a large area of around 820,000,  says it’s using the occasion to boost vaccine rates even though there may be post-pandemic vaccine fatigue.

“This is a very important initiative because it ensures that communicable diseases stay away from a region,” said Dr. Silvina Mema of Interior Health.

However, not all those doses were for COVID; the tally includes childhood immunizations plus immunizations for adults.

But IHA said immunizations are down from the height of the pandemic, when COVID vaccines were rolled out, though it seems to be on par with previous pre-pandemic years.

Interior Health says it’d like to see the overall immunization rate rise.

“Certainly there are some folks who have decided a vaccine is not for them. And they have their reasons,” said Jonathan Spence, manager of communicable disease prevention and control at Interior Health.

“I think there’s a lot of people who are hesitant, but that’s just simply because they have questions.

“And that’s actually part of what we’re celebrating this week is those public health nurses, those pharmacists, who can answer questions and answer questions with really good information around immunization.”

Mima echoed that sentiment.

“We take immunization very seriously. It’s a science-based program that has saved countless lives across the world and eliminated diseases that were before a threat and now we don’t see them anymore,” she said.

“So immunization is very important.”

Remnants of bird flu virus found in pasteurized milk, FDA says

Published

 on

The U.S. Food and Drug Administration said Tuesday that samples of pasteurized milk had tested positive for remnants of the bird flu virus that has infected dairy cows.

The agency stressed that the material is inactivated and that the findings “do not represent actual virus that may be a risk to consumers.” Officials added that they’re continuing to study the issue.

“To date, we have seen nothing that would change our assessment that the commercial milk supply is safe,” the FDA said in a statement.

The announcement comes nearly a month after an avian influenza virus that has sickened millions of wild and commercial birds in recent years was detected in dairy cows in at least eight states. The Agriculture Department says 33 herds have been affected to date.

FDA officials didn’t indicate how many samples they tested or where they were obtained. The agency has been evaluating milk during processing and from grocery stores, officials said. Results of additional tests are expected in “the next few days to weeks.”

The PCR lab test the FDA used would have detected viral genetic material even after live virus was killed by pasteurization, or heat treatment, said Lee-Ann Jaykus, an emeritus food microbiologist and virologist at North Carolina State University

“There is no evidence to date that this is infectious virus and the FDA is following up on that,” Jaykus said.

Officials with the FDA and the USDA had previously said milk from affected cattle did not enter the commercial supply. Milk from sick animals is supposed to be diverted and destroyed. Federal regulations require milk that enters interstate commerce to be pasteurized.

Because the detection of the bird flu virus known as Type A H5N1 in dairy cattle is new and the situation is evolving, no studies on the effects of pasteurization on the virus have been completed, FDA officials said. But past research shows that pasteurization is “very likely” to inactivate heat-sensitive viruses like H5N1, the agency added.

Matt Herrick, a spokesman for the International Dairy Foods Association, said that time and temperature regulations for pasteurization ensure that the commercial U.S. milk supply is safe. Remnants of the virus “have zero impact on human health,” he wrote in an email.

Scientists confirmed the H5N1 virus in dairy cows in March after weeks of reports that cows in Texas were suffering from a mysterious malady. The cows were lethargic and saw a dramatic reduction in milk production. Although the H5N1 virus is lethal to commercial poultry, most infected cattle seem to recover within two weeks, experts said.

To date, two people in U.S. have been infected with bird flu. A Texas dairy worker who was in close contact with an infected cow recently developed a mild eye infection and has recovered. In 2022, a prison inmate in a work program caught it while killing infected birds at a Colorado poultry farm. His only symptom was fatigue, and he recovered.

Canada Falling Short in Adult Vaccination Rates – VOCM

Published

 on


Canada is about where it should be when it comes to childhood vaccines, but for adult vaccinations it’s a different story.

Dr. Vivien Brown of Immunize Canada says the overall population should have rates of between 80 and 90 per cent for most vaccines, but that is not the case.

She says most children are in that range but not for adult vaccines and ultimately the most at-risk populations are not being reached.

She says the population is under immunized for conditions such as pneumonia, shingles, tetanus, and pertussis.

Brown wants people to talk with their family physician or pharmacist to see if they are up-to-date on vaccines, and to get caught up because many are “killer diseases.”
