Canadians immunized against COVID-19 with the Oxford-AstraZeneca vaccine can visit the United States when new travel regulations come into play next month, but it’s not yet clear whether those with mixed doses will make the cut.

The U.S. Centers for Disease Control and Prevention said Monday travellers will be able to fly to the States if they’ve received shots of vaccines approved or recognized for emergency use by the World Health Organization or the U.S. Food and Drug Administration.

It did not say whether that included people who had received a mixed-dose regimen of approved vaccines.

“CDC will release additional guidance and information as the travel requirements are finalized,” said a statement from spokeswoman Jasmine Reed on Monday.

The agency began informing airlines of its decision last week, she added.

Evan Rachkovsky, a spokesman with theCanadian Snowbird Association, welcomed the decision but said members had concerns and questions about those who received two different doses of vaccines.

“You’re talking about millions of Canadians who aren’t going to be permitted entry into the U.S., based on the fact that they have two different vaccine doses,” Rachkovsky said.

“We do remain hopeful that not only people with AstraZeneca, but travellers with the mixed doses as well, will be permitted entry into the U.S.”

Last month, White House officials said international travellers would be allowed to visit beginning in November as long as they were fully vaccinated. They did not say which vaccines would meet that criteria.

The U.S. Food and Drug Administration has approved three COVID-19 vaccines, and AstraZeneca was not among them. It is, however, approved by the WHO. It also does not allow for mixing doses of Pfizer and Moderna.

More than 3.9 million Canadians have two different doses of Health Canada approved COVID-19 vaccines, not including Quebec, which does not categorize data by vaccine product.

Of those, approximately 1.6 million had a dose of the AstraZeneca formula followed by an mRNA vaccine, data from the Public Health Agency of Canada shows. It’s not yet clear whether those who have received a mixed-dose regimen will meet the criteria.

The COVID-19 vaccines approved under the WHO’s emergency use listing have only been assessed as single product regimens, meaning people receive the same vaccine for both shots.

But the agency’s Strategic Advisory Group of Experts on Immunization recommends mRNA vaccines – Pfizer-BioNTech or Moderna – can be used as a second dose following a first one with AstraZeneca if a second shot of the same is not available.

The U.S. Centers for Disease Control and Prevention did not respond to a request for comment.

Canada is one of only a few countries that opted to mix vaccine types for their first and second doses last summer.

Canadian public health officials have shared data with U.S. counterparts and governments of high-priority destinations about the efficacy of mixing doses in an effort to inform their travel and border policies during the pandemic.

Mike McNaney, spokesman for the National Airlines Council of Canada, said the group welcomes the U.S. Centers for Disease Control and Prevention’s decision.

“As countries move forward and recognize WHO approved vaccines, it underscores the critical need for the Canadian government to do likewise, and accept the global standard established by the WHO,” he said in a statement.

Ottawa recognizes the Moderna and Pfizer-BioNTech mRNA vaccines, as well as the AstraZeneca and Johnson & Johnson vaccines, but not the WHO-approved Sinopharm or Sinovac shots. The U.S. Centers for Disease Control and Prevention decision means American officials will recognize all six.

Travellers to Canada can only be considered fully vaccinated if they have two doses of Health Canada-approved vaccines at least 14 days before entering the country.

Health Canada said in a statement that the list of accepted vaccines may expand in the future as research grows.

Genevieve Tremblay, a spokeswoman for Global Affairs Canada, said Ottawa “respects the right of the United States to determine its border restrictions.”

The Canadian government is working with the U.S. to recognize different vaccine strategies including mixed doses and extended intervals between shots, she said in a statement Saturday.

The new travel rules in the United States replace Trump-era travel bans that restricted visits to the U.S. by those who had recently been in the United Kingdom, the European Union, China, India, Iran, Ireland, Brazil and South Africa.

Passengers will have to show proof of vaccination before boarding, as well as a negative COVID-19 test taken no more than three days before departure.

Meanwhile the land border between the U.S. and Canada is set to remain closed until at least Oct. 21.

New technology to advance women’s cancer care at Southlake

Published

 on

NEWS RELEASE
SOUTHLAKE REGIONAL HEALTH CENTRE
**************************
This Cancer Awareness Month, Southlake is adding advanced technologies to detect and treat breast cancer and other women’s cancers thanks to generous community donor support, most recently through the HERE is Where Cancer Meets its Match campaign. New cancer care technology, including new mammography machines, the MyoSure System and the MOLLI 2® System will make a measurable impact in diagnosing and treating women’s cancers in the communities Southlake serves.

Southlake is installing three new mammography machines to expand its breast cancer screening program to 1,500 more women each year. Two of these machines have new biopsy capabilities that will reduce the number of cancelled exams due to equipment failure, ensuring timely care for women. Women ages 40 to 49 years old will be able to self-refer for publicly funded mammograms through the Ontario Breast Screening Program starting this fall.

“Early detection is critical when treating breast cancer and other women’s cancers,” said Lorrie Reynolds, Director, Regional Cancer Program at Southlake. “We treat more than 1,700 breast cancer patients at Southlake every year. By adding advanced technology, like the new mammography machines, we’re ensuring women have the best experience at Southlake.”

Southlake is also introducing the MyoSure System, an innovative technology that can help detect female reproductive cancers. Damaged tissue in a woman’s uterus such as fibroids and polyps can now be removed in a precise, minimally invasive procedure that leaves the rest of the uterus intact. This will improve the overall patient experience by supporting faster recovery, reducing the risk of infection and giving more women the option to have children. An estimated 200 women per year will benefit from the MyoSure System.

The new mammography machines and the MyoSure System build on Southlake’s recent investment in the MOLLI 2® System, a made-in-Canada wire-free breast localization technology.  This technology is considerably less invasive and more accurate when compared to wire-guided localization, resulting in a better patient experience and improved cosmetic outcomes.  More than 200 women each year will benefit from this innovative medical device as they are treated for breast cancer at Southlake.

“As a clinician caring for women with cancer in our community, I’m incredibly proud of the work Southlake is doing to advance women’s health and improve patient experiences,” said Sara Temple, MD, Surgical Oncologist and Chief of Surgery at Southlake. “Women who visit Southlake can be confident that they are receiving leading edge care, close to home when they need it most.”

The World Health Organization anticipates a 77 per cent increase in cancer diagnoses by 2050.  Southlake serves some of the fastest growing communities in Canada and anticipates that the number of patients requiring cancer care will grow. By investing in new technology, Southlake is ensuring that women in the communities it serves have access to leading edge cancer care. All of these investments were funded with support from community donors who generously gave to Southlake to support investments into women’s health at the hospital.

“The generosity of our donor community and the impact they have made for women receiving cancer diagnosis and treatment at Southlake is something we can all take great pride in,” said Jennifer Ritter, President and CEO of Southlake Foundation. “From our Women’s Health Initiative donors supporting new mammography machines, to the Ladies in Philanthropy for Southlake funding the MOLLI 2 System, to our long-standing partners The Edge Benefits and Pheasant Run Golf Club enabling the introduction of MyoSure System through their joint annual charity golf tournament, we are incredibly lucky to share a vision of access to exceptional care for everyone who depends on Southlake when they need us most. Thank you, to every donor who contributed to these important upgrades to care for women.”

Southlake Foundation’s HERE is Where Cancer Meets its Match campaign supports the Stronach Regional Cancer Centre at Southlake. For more information or to make a donation, visit: southlake.ca/HERE.

Pasteurized milk includes remnants of H5N1 bird flu, U.S. officials say

Published

 on

The U.S. Food and Drug Administration says that samples of pasteurized milk have 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 on Tuesday.

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 (USDA) 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.”

Bird flu is spreading in cows. Are humans at risk? | About That

15 days ago

Duration 8:54

For the first time ever, avian influenza, or H5N1 bird flu, was detected in roughly a dozen dairy cow herds across the U.S. About That producer Lauren Bird explores why scientists and public health officials are concerned about the cross-species transmission and whether humans are now at higher risk.

The polymerase chain reaction (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.

Tests for viable virus underway, agency says

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.

The agency said it has been evaluating milk from affected animals, in the processing system and on the shelves. It said it is completing a large, representative national sample to understand the extent of the findings.

The FDA said it is further assessing any positive findings through egg inoculation tests, which it described as a gold standard for determining viable virus.

Matt Herrick, a spokesperson 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 the 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.
