A Swiss study of 1,745 healthcare workers, published in Communications Medicine, found recent COVID-19 boosters were linked to higher risk of illness and missed work compared to the unvaccinated.

During the study, ~21% of ILI cases were COVID-19, ~20% influenza, with the rest from other viruses—suggesting boosters may increase susceptibility to multiple pathogens.
