After 35 days, a stabilization of this reduction is observed which is about 80% for the risk of diagnosis, 90% for the risk of hospitalization and admission to intensive care and 95% for the risk of death“.
The results of the recently published report give a more detailed account of the effects of vaccines in the long run. “From 105-112 days after vaccination, a further reduction in the risk of diagnosis is observed, with a similar effect in men, women and people in different age groups. There are currently no increases in the risk of diagnosis in the longer observation periods after vaccination, suggesting protracted protection over time, ”the report stresses.
