Whether vaccination confers a protective effect against progression after hospital admission for COVID-19 remains to be elucidated. Observational study including all the patients admitted to San Paolo Hospital in Milan for COVID-19 in 2021. Fully vaccinated individuals in whom vaccine failed to keep them out of hospital, appeared to be protected against critical disease or death when compared to non-vaccinated. These data support universal COVID-19 vaccination. https://doi.org/10.3390/vaccines10040550
Hello. I find this study very interesting as it elucidates whether the COVID-19 vaccination delivers a protective effect versus progression after hospitalization. It is also an incredible study with detailed experimental data from a well-established hospital in Italy. This is especially helpful since the quick vaccine development and implementation resulted in doubts about the vaccines’ safety and effectiveness. However, some say that the paper could be better if presented in a shorter form and focused on the data that contribute to the messages found in the conclusions.
