said, "We are glad that our study provides reassuring evidence on the COVID-19 vaccination effectiveness. I really believe that OMOP Common Data Model and federated analytics are the future of real-world evidence research. Extensive efforts are required at the harmonization phase but once the data...

The study confirmed thevaccine's effectiveness and its importance to control of the disease, while also showing that more than three years after the first application of a COVID-19 vaccine in Brazil, the vaccination model should be similar to that adopted for influenza, with frequent adjustments ...
In this section, we introduce the components and the trial efficacies of the vaccines. It should be noted that efficacy refers to vaccine performance in controlled trials, whereas effectiveness is drawn from real-world observations. Vaccine efficacies cannot be readily compared because the efficacy can...
Sajadi noted that the same group of researchers who conducted this latest J&J study had previously looked at vaccine effectiveness of the Pfizer and Moderna Covid-19 vaccines, which had "significantly higher" efficacy. In that study, the real-world effectivness of the Pfizer vaccine was 86.1%...
Effectiveness against severe-to-critical disease was 92.9 percent and 87.6 percent, in the short-term follow-up and long-term follow-up, respectively. The waning of efficacy was small, indicating the COVID-19 vaccine protection against severe disease remains strong at six months, according to the...
also announced similar effectiveness of its own COVID-19 vaccine candidate, which is made with the same, brand-new technology — using a snippet of the genetic code of the coronavirus to train the body to recognize if the real virus comes along. For both, “there’s every reason to be ...

Dr. Chun said, "This was the first analysis of COVID-19 vaccine effectiveness in a large population of heart failure patients, and the first to show a clear benefit from vaccination. The study provides strong evidence to support vaccination in patients with heart failure. However, this evidence...
We expect that our conclusions on the utility of updating vaccines should generalize to any updated COVID-19 vaccine, not just the fall 2022 bivalent vaccine, but additional monitoring and study of the real-world effectiveness of an annual vaccine is still necessary, and we hope that the findin...
