I cannot read German but the paper the article references is in English here https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3949410 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3949410 “ The effectiveness against severe illness seems to remain high through 9 months, although not for men, older frail individuals, and individuals with comorbidities. This strengthens the evidence-based rationale for administration of a third booster dose.” Possible difference between the Swedish study and the CDC - time period comparison of 4 months (120 days) vs 9 months (270 days) - differences in Swedish population or statistical errors. Just eyeballing CDC data on who is dying of coronavirus it’s very hard to see how any statistical analysis could show the vaccine not “working” - the smaller unvaccinated population is making up a majority of hospitalizations and deaths in the USA, and most vaccinated persons haven’t received a booster in USA. https://covid.cdc.gov/covid-data-tracker/#rates-by-vaccine-status https://covid.cdc.gov/covid-data-tracker/#rates-by-vaccine-s... https://covid.cdc.gov/covid-data-tracker/#covidnet-hospitalizations-vaccination https://covid.cdc.gov/covid-data-tracker/#covidnet-hospitali...
