When Will Covid End? We Must Start Planning For a Permanent Pandemic - Bloomberg

When Will Covid End? We Must Start Planning For a Permanent Pandemic - Bloomberg


If this is the evolutionary trajectory of SARS-CoV-2, we're in for seemingly endless cycles of outbreaks and remissions, social restrictions and relaxations, lockdowns and reopenings. At least in rich countries, we will probably get vaccinated a couple of times a year, against the latest variant in circulation, but never fast or comprehensively enough to achieve herd immunity.

South African COVID variant might evade protection from vaccine, study finds | Washington Examiner

Laat dit even op je inwerken:


The study, which was published Saturday and still requires peer review, looked at 400 individuals who tested positive for the coronavirus despite receiving at least one dose of the Pfizer/BioNTech vaccine and compared the prevalence of the South African variant, B.1.351, with the same number of people who have not yet received a vaccination.

"We found a disproportionately higher rate of the South African variant among people vaccinated with a second dose, compared to the unvaccinated group," said Adi Stern of Tel Aviv University. "This means that the South African variant is able, to some extent, to break through the vaccine's protection."

Not only could the variant "break through" protections offered by the Pfizer vaccine, but it uniquely affects those who have been vaccinated (around eight times higher) than those who have not received the vaccine — 5.4% to 0.7%.
