In the USA and Germany, high-level officials have used the term pandemic of the unvaccinated, suggesting that people who have been vaccinated are not relevant in the epidemiology of COVID-19. Officials’ use of this phrase might have encouraged one scientist to claim that “the unvaccinated threaten the vaccinated for COVID-19”.1
But this view is far too simple.
There is increasing evidence that vaccinated individuals continue to have a relevant role in transmission.

High COVID-19 vaccination rates were expected to reduce transmission of SARS-CoV-2 in populations by reducing the number of possible sources for transmission and thereby to reduce the burden of COVID-19 disease. Recent data, however, indicate that the epidemiological relevance of COVID-19 vaccinated individuals is increasing. In the UK it was described that secondary attack rates among household contacts exposed to fully vaccinated index cases was similar to household contacts exposed to unvaccinated index cases (25% for vaccinated vs 23% for unvaccinated).
Vor knapp einem Monat ist in der renommierten medizinischen Fachzeitschrift The Lancet eine Studie von E.J. Haas und Kollegen erschienen, die behauptet, BNT162b2, der Pfizer/BioNTech Impfstoff gegen SARS-CoV-2, sei hochgradig wirksam gegen die Infektion mit dem Virus, insbesondere auch gegen Hospitalisierung und Tod durch die seltene, aber gefürchtete Viruspneumonie. Doch diese Angaben sind falsch
