He is prepared to consider almost anything to convince people to take COVID shots, even if they charge unvaccinated hospital charges.

“But passports? They may be good sticks,” he said, “but I don’t know how effective they are in slowing communication.” He also passedports. I am worried that they are creating an environment of “us” that can only get worse if the pandemic continues. “We’ve seen it affect the family and divide it.” When the vaccine was polarized, “all the reasons went out of the window.”

The power of vaccines has always been in the ability to prevent serious illness, hospitalization and death in vulnerable adults. The debate was whether they would reduce the risk of infection.

They do it in a short period of time, according to a new Canadian study that has not yet been peer-reviewed. However, two doses may not prevent Omicron infection. By six months after the second dose, “it’s kind of declining, like zero,” said lead author, Toronto family doctor and epidemiologist Dr. Jeff Kwon. increase.

Updated data from his team show that efficacy against infection is restored to about 60 percent after the third dose of the mRNA vaccine. Higher, yes, “but still not great”, and not as high as Delta.

Vaccine passports were based on two purposes: to prevent infection and to help people live away from the hospital. In the latter, the shot retains its own. However, it is becoming clear that they have not completely stopped infections and infections, especially the highly infectious Omicron, whether passports are still appropriate, and why the government has not adequately addressed this issue. The question has arisen.

Dr. Martha Fulford, an infectious disease specialist at McMaster Children’s Hospital, said: “And that’s part of the whole mess.”

Passports encourage vaccination by making the lives of those who intentionally decline injections inconvenient, Kwon said. Appointments for initial doses have quadrupled after Quebec expanded its vaccine certificate scheme to cannabis and liquor stores.

However, Kwong, a senior ICES scientist, said at this point that vaccine passports help protect unvaccinated people. It can be a little difficult to explain exactly why.However, because most of the population is given twice, many people can Enter the place with your vaccine passport. “Given that the two doses were less or less effective, depending on when the last dose was, these people were probably unknowingly infected and someone else in such a situation. There is a risk of getting infected, “Kwong said.

Vaccinated people are much more likely to get a mild illness due to firing. “So they may be more likely to go out, even though they are infected,” he said. “By eliminating all unvaccinated people from these locations, we may be essentially asymptomatic or presymptomatically infected with COVID, but especially all masked. Keep them safer from vaccinated people who could be infected if not. “

“If you drop your vaccination passport, unvaccinated people will enter those spaces. Now they may be living a hermit life and were able to stay safe in that way. But if you remove the vaccine certificate, it’s like sitting on a duck. “

Dr. Andrew Morris, an infectious disease expert in Toronto, believes in one of COVID’s weekly magazines that vaccine certificates can still be harmful. Email.

“Vaccine certificates may prove valuable again at some point,” Morris wrote.

There is also the question of how many people need to be excluded to prevent a single SARS-CoV-2 infection.

Quebec’s Vaccine Passport scheme requires three final doses to shop at government-run alcohol and cannabis stores, eat indoors, enter gyms, concerts and other places. You will need. Israel has begun a fourth dose over the age of 60. Like seasonal flu, there are stories of annual shots. Streiner, a professor of psychiatry and behavioral neuroscience at McMaster University, believes there is a risk of being pushed back. “I think we’re at this stage of creating fatigue about it. Well, I have my two shots, my booster. Enough. Let me continue my life.”

Streiner is a senior author and “mastermind” of preprint research, and in the pre-Omicron era, at least 1,000 unvaccinated people to prevent one SARS-CoV-2 infection event of most types. Estimated to need to be excluded. Of the settings.

“In the fall, when people were talking about conducting mandates and some of their unvaccinated colleagues were facing dismissals, I was dismissing unvaccinated health workers. We wondered exactly what the risk reductions we could get from it, “said the lead author, Ph.D. .. Aaron Prosser, a psychiatrist who lives in McMaster. “And that only led to a broader survey of the actual numbers behind it.”

In this study, family environment, social gatherings (meaning more intimate contact between friends and family), casual intimate contact (“temporary, fleeting contact in public areas and buildings”), work and study. Settings, travel, transportation. For comparison, “going to a restaurant is probably a mixture of sociable gatherings and risks in public places,” he said.

The analysis was performed when infection rates were very stable in Canada and many parts of the world. “We were in these mid-stages of the wave,” Prosser said. “Obviously, the risk of infection is now high. It’s a completely different situation.”

“But in pluralism, we ask whether the benefits we can derive (vaccine obligations and passports) outweigh the harm of creating a class of fully unlicensed citizens. I think we need to think very carefully. Participate in society, “Prosser said.

We are starting to see our fellow citizens in such a way that they are not equal citizens to us because we have made a disagreeable decision.

Dr. Aaron Prosser

“We are beginning to see fellow citizens in ways that are not equal to us, because they have made decisions that we disagree with, and that it is very dangerous. think.”

The new federal modeling, released on Friday, will surge daily hospitalizations in the coming weeks. However, there are also signals that Omicron waves may have peaked in Ontario and Quebec. This looks like in the UK and the US. According to the Associated Press, this variant may be short of infected people. The University of Washington at Seattle scientist Ali Mokudad told AP that “it will go down as fast as it goes up.”

Other good news: “Vaccines protect against serious consequences,” Kwon said. “That’s what we need to wear a hat.”
