COVID-19 booster debate in US heads to FDA vaccine advisory committee – National | Globalnews.ca – Global News

Published

The debate over whether Americans should receive a booster dose of the Pfizer/BioNTech COVID-19 vaccine moves to a panel of independent expert advisers to the U.S. Food and Drug Administration on Friday.

While U.S. health officials, some other countries and vaccine makers have said boosters are needed, many scientists and vaccine experts disagree.

The FDA staff said in documents prepared for the committee this week that the vaccine Pfizer Inc developed with Germany’s BioNTech SE is still very effective at preventing severe illness and death and that the evidence is mixed on whether its efficacy declines over time.

Pfizer, which is arguing for broad use of a third shot, submitted data from an analysis of over 300 participants in its late stage clinical trial showing that the vaccine’s efficacy diminished by around 6% every two months after the second dose, and that an additional shot boosted immunity.

The FDA’s Vaccines and Related Biological Products Advisory Committee will also consider data from Israel, which has been administering booster doses of the Pfizer/BioNTech vaccine.

It began offering a COVID-19 booster to people as young as age 12 last month, expanding a campaign that began in July for people over 60.

An analysis by Israeli scientists published on Wednesday in the New England Journal of Medicine found that among 1.1 million people age 60 or older who had been fully vaccinated at least 5 months earlier, those who received a booster were less likely to be infected or become severely ill than those who did not get the third shot.

The Israeli Health Ministry said in documents on Friday that immunity against infection declined during July among all age groups, but particularly among people aged 60 and over who had been vaccinated in January.

Immunity against severe disease dropped in that older group, and such a decline may occur in younger groups aged 50 to 59 as well as 40 to 49, it said. The ministry also said the booster dose did not raise new safety issues.

The booster debate gained urgency as U.S. COVID-19 hospitalizations and deaths surged due to the highly transmissible Delta variant of the virus, mostly among the unvaccinated. But infections among fully vaccinated people have risen and they can spread the virus on occasion, mostly to unvaccinated people.


‘LARGER POPULATIONS MAY TAKE LONGER’

Wall Street analysts see the additional shots ultimately getting approved for a broad population.

“We expect a potential positive FDA support for boosters for elderly ahead of Biden’s rollout, but larger populations may take longer for broad support and approval,” Jefferies analyst Michael Yee said in an email.

Scientists say the strongest evidence for boosters is for older adults and other high risk populations.

“My guess is we are going to end up with a recommendation for booster doses for a certain subpopulation, such as adults older than 65,” said Bill Moss, executive director of the International Vaccine Access Center at the Johns Hopkins Bloomberg School of Public Health.

More than 1.9 million Americans have already gotten a booster dose after the government authorized them for people with compromised immune systems, according to the U.S. Centers for Disease Control and Prevention (CDC).

The panel will vote on if safety and effectiveness data support approval of a booster at least 6 months after the second dose for people aged 16 and older. The vote is scheduled for between 2:25 pm ET and 4:45 pm ET.

Eight top health officials in the Biden Administration – including the heads of the FDA and the CDC – said in August they believe booster shots will be needed because emerging data shows that protection against COVID-19 decreases over time.

The U.S. is planning a booster campaign for the week of Sept. 20, contingent on backing by the FDA and CDC.

Moderna Inc has also asked for approval of a booster and released data on Wednesday showing that protection from its vaccine also wanes over time. That is not expected to be discussed at Friday’s meeting.

Hospitals in Saskatchewan face prolonged COVID-19 crisis, modelling shows

Published

 on

COVID-19 patients will keep crowding hospital intensive care units (ICUs) in the Canadian province of Saskatchewan well into next year without government orders to limit public mixing, modelling data showed on Wednesday.

As the pandemic ebbed during the summer, the western farming and mining province lifted restrictions at the fastest rate in Canada along with neighbouring Alberta. Saskatchewan has since become the country’s  COVID-19 hotspots, with the lowest vaccination rate among provinces, and had to hastily reimpose restrictions such as masking in indoor public places.

“I have no shame in pleading to the public, that we’ve gone so far and we just have to pull along for the next weeks and months,” said Saskatchewan’s Chief Medical Health Officer Dr. Saqib Shahab, who broke down with emotion during a media briefing. “It is distressing to see what is happening in our ICUs and hospitals and I’m sorry — it’s a very challenging time.”

The pandemic’s spread has forced Saskatchewan to fly some COVID-19 patients to Ontario for care and to cancel thousands of surgeries.

Saskatchewan’s modelling showed that severe cases will continue to overwhelm ICUs until March before beginning to decline, without a reduction in mixing, such as smaller gatherings, and greater access to vaccine booster shots. Reduced mixing should ideally last at least 28 days, Shahab said.

The provincial government, led by Premier Scott Moe, has declined to impose limits on private gatherings, however.

Canada’s daily case counts spiked in late summer, but have declined recently. Cases in Saskatchewan and Alberta have also started trending lower, however they have still recorded the highest rates of deaths among the 10 provinces in the past week, and the highest rates of active cases.

SHA says COVID-19 protocols prevented a flu season last year – moosejawtoday.com

Published

 on


The Saskatchewan Health Authority says last year’s flu season was prevented thanks to masks, physical and social distancing, and increased hand washing.

Dr. Tania Diener, the COVID-19 Immunization Co-Chief at the province’s Emergency Operations Centre, says that, “We effectively didn’t have a flu season here last year.”

With restrictions slowly lifting from a population feeling the stress of isolation and public health measures, the province is uncertain about whether or not a flu season will return this winter.

Dr. Diener emphasized that, “Our hospitals are already under strain due to the number of cases of COVID-19, especially among those who are unvaccinated, due to the new Delta variant. A further influx of people sick with influenza would further strain those resources, so we’re asking everyone to get their flu vaccine again this year.”

SHA says they have enough evidence at this point to conclude that receiving a COVID-19 vaccine and a flu vaccine together is safe, and they encourage everyone able to do so to get both vaccines as soon as possible. 

This year’s flu vaccine is quadrivalent, meaning it protects against four different flu variants, an improvement from last year’s, which was trivalent. 
Information on this year’s flu vaccine can be found here.

Province says flu shots prevents serious illness, deaths – My Comox Valley Now

Published

 on




The province wants you to roll up your sleeves for another kind of vaccine as we head into flu season.

Health officials are hoping you will take their advice and get a flu shot, which is free for everyone in B.C. older than six months.

They say the unique circumstances of the COVID-19 pandemic and the strain it has put on the health-care system continue to make influenza immunization a priority.

“All British Columbians should get vaccinated against influenza to protect themselves and their loved ones from serious illness, to reduce the strain on our hard-working health workers and to do our part to make sure the health system continues to be there for people who need it, where they need it and when they need it,” said health minister Adrian Dix. 

“I’m grateful to all of our health-care workers, including physicians, pharmacists, nurses, nurse practitioners and others for how they help people get immunized to protect themselves and those they care about.”

Seasonal influenza and other respiratory viruses will be in communities alongside COVID-19 this fall and winter.

The province says it “has the potential to escalate pressures already faced by the health-care system, particularly if the effects from COVID-19 and seasonal influenza occur are the same.”

That is why vaccines are now available and the province continues to increase vaccine accessibility through many locations and vaccine providers throughout B.C.

“This year, it’s especially important for people to get vaccinated against influenza. Last year’s low influenza rates means our immunity against influenza is lower than usual,” said provincial health officer, Dr. Bonnie Henry. 

“Getting your influenza vaccine this year is more important than ever to protect yourself, your community and our overstretched health-care system.”

Pharmacies around B.C. have played a key role in providing easy access to influenza vaccines since 2009. 

This year, vaccines are available to pharmacies through a direct-distribution model. 

This means pharmacies are able to order them directly from distributors, which the province says makes “influenza immunization easier and more flexible for people in B.C.”

“Pharmacists played a key role in helping people get immunized against COVID-19 earlier this year and administered the majority of influenza doses last year,” said Geraldine Vance, CEO, B.C. Pharmacy Association. “We’re proud of the role we continue to play in protecting our health-care system and keeping everyone safe.”

Flu vaccines have been available already for certain high-risk groups. 

As they become available more broadly to the public throughout the province, you’re asked to check their health authority’s website or call their health-care provider or pharmacist to check for availability and to make an appointment.
