Evaluation of the Natural Immunity to Alberta Vaccine Passport Program

The Alberta government is looking into whether people with natural immunity against COVID-19 may qualify for its new vaccine passport, although it is unlikely to go into effect any time soon.

“We’re looking into it,” Premier Jason Kenney said during a live public question-and-answer session facebook on 17 september.

He was responding to a question whether people who have previously recovered from the virus still needed vaccination to access services, given that they had developed immunity against the risk of reinfection.

“I have said that we look at this more closely to see if we can replicate it here as a feature of our program,” Kenny said, noting that Israel and Denmark have shown evidence of antibodies in their vaccine passport systems. allowed to include. .

Kenny said the exemption would not come any time soon because it is “logically impractical” to implement the system, noting that the province cannot wait weeks to develop a system that has evidence of antibodies. especially in view of their “decreasing” effect.”

He pointed to studies conducted by the Cleveland Clinic in Ohio and Maccabi Healthcare Services in Israel that both show “very high levels of protection against COVID in people who already have an infection, but that over time.” diminishes.”

The Cleveland Clinic study, released as a preprint (non-peer-reviewed paper) in June, states that “COVID-19 occurred among 2579 individuals previously infected with COVID-19 in none in the five months of the study.” also did not occur, which included 1359. Not vaccinated.” The study indicates that it was “not specifically designed to determine the duration of protection from natural infection.”

The Maccabi study, possibly referring to work done by the Maccabi Research and Innovation Center and also published as a preprint in late August, shows that SARS-CoV-2-naive vaccines (vaccinated without immunity) individual) had a 13-fold increased risk. “For successful infection with the delta variant compared with those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021.”

The study further states that “there is evidence when infection is allowed to occur at any time prior to vaccination (from March 2020 to February 2021).” LilyNatural immunity was demonstrated, “although people who were vaccinated had an approximately six-fold increased risk of breakthrough infection and a seven-fold increased risk for symptomatic disease. Vaccinated people” compared to those previously infected. Were at greater risk for COVID-19-related-hospitalisation.”

The effectiveness of mRNA vaccines diminishes over time, a fact confirmed by manufacturers Pfizer and Moderna, which has prompted the Israel and Biden administrations to push for a third dose to the general public.

Israel has expanded booster shots to everyone over the age of 12, while some other countries are making them available to vulnerable populations at higher risk. Meanwhile, the White House is facing resistance from the Food and Drug Administration.

In Canada, the National Advisory Committee on Immunization strongly recommends that individuals who have been fully vaccinated receive an additional dose of mRNA vaccine.

in press conference September 15Kenny said that if COVID cases continue to rise, the Alberta health care system “could run out of staff, intensive care beds within the next 10 days”. He also canceled “thousands of surgeries and other procedures” to free up resources and staff and expand hospital capacity for COVID patients.
