Years ago my brother said the population is being immunized by infection. Most infections with the current SARS-CoV-2 virus are asymptomatic. The previous post https://luysii.wordpress.com/2024/05/02/useful-covid-information-which-should-have-been-published-2-years-ago/ contained the following information
Despite the fact that 1.3% of the Danish population studied from 1/18 to 1/22 had a positive antibody test for SARS-CoV-2 (76,700 people) at most times, the maximum number of people hospitalized for COVID19 was 495, meaning that the infection was incredibly benign (495/76700 = .0065 an under 1% chance of hospitalization.
The statistic also means that most infections back then were asymptomatic.
Today’s Nature [ vol. 629 pp. 269 – 270 ’24 ] noted that zero of 35 volunteers could be infected with what was thought to be the current strain of the virus. Why do such a thing, to find a virus which could be used to test vaccines against the pandemic virus. This clearly implies that most of us are immune because of previous symptomatic or asymptomatic infection.
Also CNN reports that Astra Zenica is withdrawing its vaccine presumably because no one is using it and because other vaccines are available.
AstraZeneca is withdrawing its highly successful coronavirus vaccine, citing the availability of a plethora of new shots that has led to a decline in demand.
The vaccine — called Vaxzevria and developed in partnership with the University of Oxford — has been one of the main Covid-19 vaccines worldwide, with more than 3 billion doses supplied since the first was administered in the United Kingdom on January 4, 2021.
