Unvaccinated people 11 times more likely to die from COVID – CDC report – Barrie 360

Unvaccinated people were 11 times more likely to die from COVID-19 compared to those who were fully vaccinated, the Centers for Disease Control and Prevention reported in a new study Friday, providing more evidence of the vaccines’ effectiveness at preventing severe disease, even as protection from mild breakthrough cases appears to be waning in the face of the Delta variant.

“Looking at cases over the past two months when the Delta variant was the predominant variant circulating in this country, those who were unvaccinated were about four and a half times more likely to get COVID-19, over 10 times more likely to be hospitalized, and 11 times more likely to die from the disease,”  CDC Director Rochelle Walensky said at a briefing Friday.

The CDC’s latest data, published as three studies Friday in the agency’s Morbidity and Mortality Weekly Report, are also the latest sign that booster shots could become necessary in the coming months for many. 

Examining the incidence of COVID-19 across 13 jurisdictions in the United States, the CDC reported that the odds of fully vaccinated people becoming sick with the virus rose as the Delta variant surged across the country.

Scientists expected fully vaccinated people to make up some 10% of cases from late June through July, if the shots retained peak effectiveness at preventing any infection. Instead, vaccinated persons accounted for 18% of observed cases — a finding the study’s authors said “were consistent with a potential decline in vaccine protection against confirmed SARS-CoV-2 infection.”

However, while protection against hospitalization and death remained relatively high in the study through mid-July, the CDC also published new data showing further evidence of waning protection against severe disease in the oldest Americans.

In data collected from the agency’s “VISION Network” cohort of hundreds of hospitals and urgent care clinics, the agency reported that vaccine effectiveness against hospitalization in adults 75 and older “was significantly lower” than in younger patients through August. A handful of Veterans Affairs Medical Centers reached a similar conclusion in their data, estimating effectiveness against hospitalization for adults 65 and older at 80%.

Both studies reported that their findings of declining effectiveness against hospitalization had not been previously observed in their cohorts.

The CDC has previously reported vaccine effectiveness against hospitalization appearing to drop over time in other cohorts, though still remaining above 80% through July. 

The new results come as federal health officials say they are moving ahead with plans to roll out booster shots nationwide, pending approval from the Food and Drug Administration and formal recommendations from a panel of the CDC’s expert vaccine advisers.

Pfizer is expected to be first to win approval from the FDA for a booster shot. The regulator plans to convene its panel of vaccine experts to deliberate over the company’s booster shot data next week, ahead of the administration’s planned rollout the week of September 20th.

Federal health officials say they also hope to allow for booster shots for recipients of Moderna and Johnson & Johnson’s vaccines in the coming weeks, pending more data from the drugmakers.

The Biden administration has also pointed to data collected abroad to underscore the need to roll out additional doses of the vaccine for those most at-risk; Israel, for example, has already begun administering booster shots.

“Israel has been a very interesting phenomenon to observe, because they seem to be ahead, certainly of the United States, in every element of the outbreak, including response to vaccines,” Dr. Anthony Fauci, the president’s chief medical adviser, told a virtual event hosted by the London School of Hygiene and Tropical Medicine on Wednesday.

Yale University researchers, in a federally-funded preprint study that has yet to be peer-reviewed, recently reported the early booster shot rollout there appeared to reduce the odds of infection by up to 68%.

Israeli health officials have also briefed the Biden administration on additional unpublished data from their booster program. The country’s prime minister recently urged President Biden to speed the U.S. booster strategy, which currently plans for Americans to get their additional shots 8 months after completing their initial regimen.

“Although earlier studies showed that hospitalization protection, most recent studies, in my personal communication with Israeli health authorities, indicate that there’s even now a significant diminution,” added Fauci.

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.
