Hesitancy over a COVID-19 vaccine may threaten public health

  Hesitancy over a COVID-19 vaccine may threaten public health Health experts say that public mistrust over vaccines and related resistance to getting vaccinated could pose a serious challenge for curbing COVID-19.Karyn Methven, a cancer survivor, is terrified of contracting COVID-19. “Gosh, this is really urgent,” says Methven, of Delta, BC. “We’ve hit the 10-thousand mark now in Canada, you know. Ten thousand deaths.

Why a coronavirus vaccine might be ready early next year — and what could go wrong. U.S. officials and scientists say they are hopeful a vaccine to prevent Covid - 19 will be ready in Even the most optimistic epidemiologists hedge their bets when they say it could be ready that quickly.

And I'm cautiously optimistic that not only that candidate but a number of other candidates that we at the NIH are partnering with our Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, says he's hopeful a vaccine for Covid - 19 will be developed by the winter.

Pfizer's vaccine candidate is one of a handful that Canada has announced deals to reserve.

Top health officials say they are "cautiously optimistic" about Canada's odds of obtaining a safe and effective COVID-19 vaccine for distribution sometime in the first quarter of 2021.

But even if that timeline is met, Chief Public Health Officer Dr. Theresa Tam warns that doses would be in short supply at first — which would force governments to decide who gets immunized first.

  Meet the super-rich families of the 1920s A decade like no other, the Roaring 20s saw some of America's wealthiest entrepreneurs rise to prominence and amass enormous wealth. Here are the 17 richest men and women of the Jazz Age – who’d all be billionaires in today’s money.

Health officials have set targets for how good and how safe a COVID - 19 vaccine needs to be , but communicating that to the public can present challenges. For the COVID - 19 vaccine , the ideal candidate would be able to establish immunity in at least 70 percent of the population.

Health officials have said that a vaccine could be ready next year , if we take some shortcuts. Experts told Live Science that, for any other vaccine , the timeline would be unrealistic. But given the current pressure to stave off the pandemic, a COVID - 19 vaccine could be ready sooner, as long as

"While that supply will continue to increase over time, it does mean that federal, provincial and territorial governments will have to make important decisions about how to use the initial vaccine supply," Tam told reporters at a press conference Friday.

Tam said preliminary guidelines published earlier this week by Canada's National Advisory Committee on Immunization (NACI), a multi-disciplinary panel of experts, should help guide decisions on who should be first in line.

Key populations identified by NACI for early immunization include seniors and people with high-risk conditions, health care workers, long-term care providers and people who can't work virtually, such as police, firefighters and grocery staff.

Despite Pfizer success, a lot has to happen before vaccine rollout in Canada: experts

  Despite Pfizer success, a lot has to happen before vaccine rollout in Canada: experts Pharmaceutical giant Pfizer says early results from its coronavirus vaccine trial suggest a 90 per cent efficacy rate at preventing COVID-19, a number that has Canadian infectious disease experts cautiously optimistic that a viable shot can be rolled out by spring of 2021. Jean-Paul Soucy, an epidemiologist at the University of Toronto, called Pfizer's announcement "fantastic news (and) very encouraging," but there are still questions to be answered. And there are many steps between a vaccine's approval and its actual rollout. "It's important to temper our expectations," Soucy said.

The vaccine will not be mandatory. Putin named it Sputnik V, an appropriately named drug seeing how the original Sputnik was the name of the rocket that started the space race Some skeptics doubt that Russia will be able to role out the vaccine in large quantities by year ’s end, and others have said that

"There are many conversations to be had about who gets those first doses of vaccines," said Prime Minister Justin Trudeau.

"The most vulnerable, Indigenous peoples, frontline health workers — these are the kinds of populations we're looking at for their high degree of vulnerability. But of course, those are conversations that will be had amongst provinces and territories and including experts."

Canada betting on multiple vaccine candidates

The Government of Canada has signed deals with several teams of vaccine developers to reserve millions of doses of COVID-19 vaccines in various stages of development — an effort to make sure Canadians can start getting immunized as soon as a vaccine becomes available.

While many vaccine candidates have shown promising early results, Tam warned that further research must be done in clinical trials to ensure they are safe and effective and Health Canada still needs to evaluate and approve any vaccines before they can be distributed.

'A great day for science' with promising early COVID-19 vaccine results

  'A great day for science' with promising early COVID-19 vaccine results The results of Pfizer’s COVID-19 vaccine trials aren’t final, but they are promising, leading one of Canada’s top scientists to declare it a “great day for science and for all of the planet. “I am pretty excited today,” said Alan Bernstein about the announcement from Pfizer on Monday that its COVID-19 vaccine is more than 90 per cent effective, according to early data. Bernstein is president and CEO of the global research organization CIFAR and a member of Canada’s COVID-19 vaccine task force. That task force made recommendations to the Canadian government about which vaccine candidates it should purchase.

A COVID - 19 vaccine could be available earlier than expected if ongoing clinical trials produce overwhelmingly positive results, Dr. Anthony Next on the priority list should be people of all ages with underlying conditions, the report said. A vaccine probably would be in scarce supply initially, with

Public health officials and scientists expect to know whether at least one of the numerous potential Covid - 19 vaccines in development is safe and effective by the end of December or early next year , he said. "I think as we get into 2021, several months in, that you would have vaccines that would be

Health Canada has so far received three official applications for vaccine approval, all of which are under review: from U.K.-based AstraZeneca, which is manufacturing a vaccine developed at the University of Oxford; from U.S. biotechnology firm Moderna, which launched the first Phase 3 clinical trial in the U.S. in July; and from U.S. pharmaceutical giant Pfizer and German biotechnology company BioNTech, which are collaborating on a vaccine.

"We will be receiving additional advice on prioritization based on the characteristics of each vaccine once approved," said Tam.

Beyond deciding who will get priority, bureaucrats at all levels of government are working to ensure the infrastructure and equipment is in place to distribute vaccines once they are ready, said Deputy Chief Public Health Officer Dr. Howard Njoo.

That work includes procuring equipment (such as syringes) and ensuring there is cold storage infrastructure in place to store and transport vaccines — some of which need to be kept at extremely low temperatures.

Njoo pointed out that the vaccine furthest along the development phase needs to be stored at -80 C, which could pose logistical challenges for the pharmacies and doctor's offices typically involved in vaccine distribution.

"That's not the way most vaccines in Canada in the past ... in fact, none of them have been obligated to have that kind of cold chain in terms of logistics," said Njoo. "We have to ... work out the mechanics in terms of buying the right kinds of freezers, etcetera, the transportation mechanisms, etcetera, to be able to assure that if that's the first one out of the pipeline that get's approved ... that we're able to do that in the most effective and efficient manner."

Njoo said all vaccines will be free of charge to all Canadians once they become available.
