NACI’s advice on ‘favorite vaccines’ for COVID-19 causes confusion, anger

OTTAWA – The National Advisory Committee on Immunization is under fire that Canadians have been receiving weeks to take the first vaccine against COVID-19 that they are offered.

NACI said Monday that Pfizer-BioNotech and Modern Vaccine are “favorites” and that Canadians risk waiting for one of them before deciding to take one or more of the other two immediate jabs approved for use in Canada. Should be raised.

Johnson & Johnson and AstraZeneca vaccines have been linked to a new and extremely rare blood-clotting syndrome.

Because of this, the vice chairman of the committee, Drs. Shelley Deeks said that a person working from home in a province where there is not much disease wants to wait for a shot of Pfizer or modern vaccines.

But she said it would be a very different risk-benefit analysis for someone working in a manufacturing plant without personal protective equipment in the province where COVID-19 is spreading like wildfire.

NACI’s advice appears to contradict Health Canada’s long-standing recommendation that the best vaccine is available first.

Some doctors took to social media to reject NACI’s latest advice, warning that the committee was causing confusion and increasing vaccine hesitation.

Emergency Physician Dr. Brian Goldman said on Twitter, “It hurts me to say this but it’s time to recommend NACI with a grain of salt.”

“For the good of your health, when it comes to #covidvaccines, don’t choose to choose it. Take the first offer you give.”

Those who became innocent with AstraZeneca also took to social media to express anger that they were hoodwinked into getting a second-rate vaccine, while others questioned whether they should cancel the first plan for that vaccine Or refusal to take a second dose.

A Twitter user mentioned acidity that NACI’s advice “provokes those who are at risk should they compromise for the most high-risk vaccine because they are most at risk.”

NACI chair, Drs. Carolyn Quach-Thanh only made matters worse when she tried to explain the committee’s advice during an interview on CTV’s Power and Politics on Monday.

“If for example my sister got the AstraZeneca vaccine and died of a thrombosis when I know it could have been prevented and she is not in a high-risk area, I’m not sure I could live with it, ” He said.

The risk of a new blood-clotting syndrome known as vaccine-induced thrombotic thrombocytopenia, or VITT, is estimated to be anywhere from one case per 100,000 doses to one given in 250,000. But the syndrome is so new, there is still little information about what the real risk is, why it is occurring and who is most likely to develop clots.

In Canada, seven cases have been reported of all people receiving the AstraZeneca vaccine. Some 1.7 million doses were given by 24 April.

As of April 23, out of more than eight million doses of the J&J vaccine administered in the United States, 17 cases of VITT were confirmed.

Health Canada has approved the J&J for use in Canada, but none of the Canadians have received it because the first batch given last week is still under investigation, security at the US facility involved in its production and After a quality control violation was reported.

NACI states that people in the provinces and territories may want to prioritize J & J, the only single-shot vaccine ever approved in Canada, for people who have difficulty scheduling a second dose. It recommends that Jammu and Kashmir, like AstraZeneca, be given only to people over 30 years of age.

Conservative MP Michelle Rempel Garner has raised confusion over the NACI’s latest advice in the House of Commons on Monday.

“This is a lot different than what we are hearing. Does Health Canada recommend taking the first vaccine offered or waiting, if one can do the mRNA (Pfizer or Modern) vaccine?” He asked.

Health Minister Patty Hajdu replied that Health Canada is responsible for approving vaccines for use while NACI gives the best advice to advise them. He advised Canadians to ask their health care provider which vaccine is right.

AstraZeneca and J&J are both viral-vector vaccines, a technique that takes a common cold virus, manipulates it so that it doesn’t make anyone sick, and then engages the spike proteins of the SARS-CoV-2 virus Which causes COVID – 19. The vaccine helps the body mount an immune response that will recognize and fight an actual SARS-CoV-2 virus if it ever comes into contact with one.

Pfizer and Moderna use the mRNA technique, attaching the spike protein to a molecule that sends a message to the body to perform certain functions. In this case the message is to mount an immune response to the SARS-CoV-2 virus.

In Canada so far, 12.8 million people have received at least one dose of a vaccine. About two-thirds of them received Pfizer, one-fifth received Modern and the rest AstraZeneca.
