A recent study from Qatar shows that people who acquired natural immunity to the original Wuhan strain had excellent protection against severe disease from later variants, some of which were more virulent.
Macron wants to "piss off" the unvaccinated because they place a burden on the health service. But obese people place a burden on the health service too. Will Macron's next policy be "pissing off" the obese?
We already know that people overestimate the risks of Covid. A new survey has found that a sizeable majority of Democrats wrongly believe the vaccines protect better against infection than natural immunity.
In an email obtained via FOI request, the former head of the NIH described the Great Barrington authors as "fringe epidemiologists" and called for a "take down" of the Declaration. Now two of them have hit back.
Omicron is very different from the previous variants of concern, and a new study presents evidence that it evolved specifically in mice. Which raises an intriguing possibility: did Omicron leak from a lab?
A few months ago, case rates were highest in the least vaccinated states. Now they're highest in the most vaccinated states. As in Europe, vaccine passports have done almost nothing to prevent transmission.
November's age-standardised mortality rate was 8% higher than the five-year average, and there were 5,000 more deaths than last month. However, much of the increase was accounted for by non-Covid causes.
A fourth study has found that natural immunity protects better against infection than the vaccines. Indian researchers estimated the protective effect of natural immunity to be 86%; vaccine effectiveness was only 32%.
Throughout the pandemic, those in favour of more restrictions have argued that restrictions drive behaviour and behaviour drives infections. Yet rising mobility frequently coincides with falling case numbers.
Back in January, Sir Patrick Vallance said, "The more you vaccinate, the more you put evolutionary pressure on the virus." A recent paper argues that mass vaccination has selected for vaccine escape mutations.
