Look what happens if I highlight the other words. It's almost like everyone just ignores that parts that don't go along with their personal views.
Our data provide evidence that a fourth dose of mRNA vaccine is immunogenic, safe, and
somewhat efficacious (primarily against symptomatic disease). A comparison of the initial response to the fourth dose with the peak response to a third dose
did not show substantial differences in humoral response or in levels of omicron-specific neutralizing antibodies. Along with previous data showing the superiority of a third dose to a second dose,
4 our results suggest that maximal immunogenicity of mRNA vaccines is achieved after three doses and that antibody levels can be restored by a fourth dose. Furthermore,
we observed low vaccine efficacy against infections in health care workers, as well as relatively high viral loads suggesting that those who were infected were infectious. Thus,
a fourth vaccination of healthy young health care workers may have only marginal benefits. Older and vulnerable populations were not assessed.
