More COVID-19 vaccine is coming to B.C., but questions remains about logistics – Global News

Published

 on


B.C.’s top doctor says she understands that British Columbians are frustrated by the pace of vaccinations in the province, but she says more doses are on the way.

“It is what it is,” provincial health officer Dr. Bonnie Henry said.

“It doesn’t make vaccine come any quicker to be upset or angry or mad about it. We’re playing the hand we were dealt and we are committed to getting immunizations as fast into people’s arms to protect people as we receive them.”

Canada’s shipment of the Pfizer-BioNTech COVID-19 vaccine will be delayed by one day due to a winter storm wreaking havoc in the United States, the company confirmed.

Henry said Pfizer has committed to providing increased doses between now and the end of March, and she is hopeful the province will receive an increased number of doses from Moderna.

With deliveries set to ramp up, Henry said she is now confident the gap between vaccine doses can safely be extended to up to three months if necessary.

In B.C., researchers have monitored vaccinated residents of long-term care homes after they connected with people with COVID-19, Henry said.

In the three weeks after the initial dose, the protective effect of the vaccine was nearly 90 per cent, she said.

“As a scientist and somebody who has worked in the field of vaccines for quite a long time, this is actually incredibly exciting and positive news that we have this very high level of protection in seniors here in B.C. from the first dose of the vaccine,” Henry said.

Prime Minister Justin Trudeau has said Canada is on track to get six million vaccinations by the end of March and tens of millions through the spring.

Mahesh Nagarajan, a professor of operations and logistics with UBC’s Sauder School of Business, says those numbers are a best-case scenario.

“My hope is that the provinces have come with a very robust plan to vaccinate the different segments of the population so we can get to a target by September,” he said.

Nagarajan says the logistics of mass vaccination are daunting.

“Let’s assume that we have about four million people left to vaccinate in B.C. — and I’m being generous because it’s actually more than that — and we are going to start on the 1st of March, we’re looking at approximately 19,000 vaccinations a day, and this is simply assuming one shot of vaccine,” he said.

“At some point, we have to ask if we have the logistics that can actually get these many shots into people’s arms.”

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.

300x250x1

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.”
