UK reopens to 30% vaccinated while Canada waits 75% – fr


The 75% fully vaccinated threshold is based on modeling the population “with many different parameters and assumptions to be met,” said Dr Theresa Tam.

Across the UK, where 30% of the population is fully vaccinated against COVID-19, people are free to start ‘cuddling cautiously’, pubs are reopening and millions are socializing again so as the country emerges from a grim four-month lockdown.

In the United States, the Centers for Disease Control and Prevention said fully vaccinated Americans, about 37% of Americans as of Monday, could, with few exceptions, safely ditch their masks, stop distancing and congregate indoors with people they don’t. live. Fans are distancing themselves from baseball stadiums, Broadway is expected to reopen in September, and New York State County Fairs are expected to resume this summer.

Canadians, meanwhile, have been told they can expect a similar taste of life pre-COVID, but not until 75% of those eligible for vaccines have achieved full immunization status, or two weeks. after the last dose of vaccine. On Monday, that figure was less than 4%.

The 75% target is part of the guide “Life After Vaccination” released Friday by the Public Health Agency of Canada, a “road map”, as described by Minister of Health Patty Hajdu, what some reviewers say is so poorly detailed that it could have been sketched out on the back of a cocktail napkin. Others wonder why Canada’s target is so much higher than in other countries.

The advice came days after Prime Minister Justin Trudeau’s confused message “one summer dose, two fall doses”. While it may sound catchy “in a strange way,” trying to explain complex issues with a simple slogan can be problematic, says Dr Gerald Evans, director of the division of infectious diseases at Queen’s University in Kingston, in Ontario.

A “single-dose” summer, according to the health agency, actually doesn’t look much different from last summer without vaccines, with only camping, hiking, patio dining, and kids. Outdoor picnics on the horizon, 75% of eligible Canadians received a dose, and 20% of them a second.

In the fall, if the cases are low and the two-dose vaccination is high, ” ensuite (government emphasis in bold) local public health will be able to lift more action and you should be able to do more activities indoors with people outside your household, ”wrote the public health agency, like attending “colleges, indoor sports, family reunions.” “

Yet the restrictions are squarely within provincial jurisdiction, and provinces and territories can choose to ignore the Ottawa minimum guidelines.

According to the data Evans saw, “If we had about 80% of the population with two doses of the vaccine by September 1, we would have a nearly normal looking drop.”

Several provinces are already promising better. Saskatchewan plans to make second doses available to everyone by mid-July, while Ontario “will strive for a two-dose summer,” Ontario Premier said on Friday , Doug Ford.

The 75% fully vaccinated threshold is based on modeling projections “with many different parameters and assumptions to be met,” Canada’s director of public health, Dr. Theresa Tam said on Friday.

“But I think having a big goal is really good for everyone,” she said. The UK, hit by a devastating third wave, “smashed that curve, this very massive third wave, to really low levels by the time they hit that kind of immunization coverage. Canada, by comparison, is just starting to peak in many provinces and territories, Tam said.

What’s different about this summer, Tam proposed, is that an injection of a COVID-19 vaccine should make people feel more secure that they are better protected, even if “you have to get this. second dose for maximum protection. “

But due to the lack of clarity, some people try their own calculations down the line.

“One that I’ve heard a few times already works like this: ‘Wait a minute. These are the global thresholds. Can I create a slightly larger “bubble” of family members and trusted friends from two or three households who have all had 1 or 2 shots and have minimal outdoor exposure? Isn’t that the equivalent of 100% coverage, ”said Dr. David Naylor, co-chair of the Canadian COVID-19 Immunity Working Group, in an email.

“These types of questions need to be answered as soon as possible,” Naylor said.

There are now concerns about the infectivity of the B.1.617 variant which first appeared in India, but the two mRNA vaccines – Pfizer-BioNTech and Moderna – appear to offer reasonable protection, Naylor said.

“So the key is to vaccinate as many Canadians as possible as quickly as possible,” he said, including catching up to a higher proportion of second doses, “even if we run ahead with the first doses,” to reach that threshold of 75% for the total. population coverage.

If restrictions are completely dropped before this goal is achieved, the incentive to get vaccinated may decrease. The United States is already struggling with vaccine hesitation. The number of Americans seeking vaccines has fallen by a third in recent weeks, Reuters reports, prompting businesses and health officials to offer alcohol, baseball tickets and other freebies to persuade people to get vaccinated.

The UK experienced a raging epidemic, which Canada avoided, before starting to vaccinate. “We had a much smaller epidemic. So there are more people in the UK who have gained immunity through natural infection, ”said Amir Attaran, health policy expert at the University of Ottawa. There is preliminary evidence from several small studies that a single injection of the Pfizer of Moderna vaccine can trigger a rapid immune response in people previously infected.

“In Canada – and this is the good news – quite a few people compared to the UK have achieved immunity through natural infection, so if anything we have to outperform UK vaccination performance to be in one place. Said Attaran.

Likewise, the United States has experienced a “raging (former US President Donald) Trump epidemic, so the first dose that many people received is in fact, functionally, more similar to the second.” , did he declare.

“It all depends on the double attack mode,” Evans said. “Vaccinate the living daylight of the people and bring those numbers down and don’t come out of the restrictions until those numbers have dropped to a point where public health says, ‘No problem, we’re on top of it, we got it under control. can handle it from here with our Outbreak Management. “
