Re: What we know about covid-19 reinfection so far
To update on the number of reported covid-19 reinfection cases. There are currently 39 documented cases of Covid-19 reinfection listed on the Cov-19 reinfection tracker site, with reference citations. Of the 39 cases there were 34 recovered and two deaths. The mean time interval between cov-19 infections was 92 days, about 3 months, this makes the Chief Medical Officer's recommendation of extending the vaccination interval from 3 weeks to 12 weeks unsound as one can acquire an infection between jabs.
This contrasts with the findings of the recent Siren study which suggested immunity in health workers who had a previous Cov-19 infection were immune for 5 months. Clearly this duration of immunity cannot be reproduced in the general population, who will show considerable variation.
The $64bn question is how long is the immunity provided by each of the current vaccines, Pfizer, Moderna, Oxford Astra Zeneca? If this is as yet still unknown why has the regulator allowed approval? Surely this should have been determined by a follow up study before roll out.
