Var inte helt enkel att läsa tycker jag, men kan följande slutsatser i artikeln verkligen visa på ett uruselt skydd?Mer om att skyddet kan vara uruselt efter genomgången COVID19:

Anti-spike antibody response to natural SARS-CoV-2 infection in the general population
/.../In conclusion, in this representative study of infected individuals from the UK general population, around 1 in 4 people did not develop anti-spike IgG antibodies following a positive PCR test in regular screening. Non-responders were more likely to be older and not report symptoms. Among participants who seroconvert, anti-spike IgG antibodies remained above the positivity threshold for an average of 380–590 days for 20-year-olds, 410–649 days for 40-year-olds, 441–703 days for 60-year-olds and 471–755 days for 80-year-olds. These estimates of the durability of natural immunity may aid planning of the vaccination strategies. Further studies are required to determine the extent to which waning antibody levels impact immunity and protection following infection and vaccination and to assess the risk of infection in seronegative non-responders.https://www.nature.com/articles/s41467-021-26479-2
”(...) we found that 50% protection against infection might be expected to last 1.5–2 years, with protection against severe infection potentially lasting several years (...)”
”Overall, at least in the short-term, protection against re-infection appears high.”
