| haxxiy said: Data from the past weeks in Denmark suggest that the fully vaccinated are three times less likely to be infected than the unvaccinated (~ 67% efficacy), and the previously infected six times less likely than the unvaccinated (~ 84% efficacy). Vaccination plus previous infection provides a whopping 30 times reduction in risk (~ 97% efficacy). This is vs. testing positive only, so no data on symptomatic illness or hospitalizations yet. Contrary to my fears, that would suggest protection from previous infection is holding out well despite the cooler temperatures that would have dried out nasal mucosae and decreased the levels of IgA in the nose. It also suggests the percentage of previously infected in Eastern Europe was likely quite a bit lower than needed for herd immunity, perhaps no more than 50% before this wave. |
Yet, governments are pushing for boosters to everyone whether if they had covid19 in the past or not. Absolute insanity.
