Corona Vaccine Continues to Protect Against the Most Dangerous Consequences

"In light of the generally less severe courses of SARS-CoV-2 infections and the declining acceptance of annual Covid-19 vaccinations among the population, current evidence of the vaccines' effectiveness regarding clinically relevant outcomes is required," according to the results of the US veterans study on the Corona vaccine.

Corona Vaccine: People with Chronic Diseases Benefited Particularly

The scientists from the Center for Epidemiology of the US Veterans Affairs analyzed the health data of 164,132 US military veterans who were vaccinated against Covid-19 between September 3, 2024, and December 31, 2024. Their information was compared with that of 131,839 members of a comparison group who had only received an influenza vaccination through the healthcare of former US military personnel. The follow-up period was six months. The authors wanted to determine exactly how the effect of the vaccination was in the 2024/2025 season.

Although the frequency of severe disease courses during the Covid-19 pandemic waves has decreased since 2020, the epidemiological analysis showed a consistently positive effect of the vaccination with the vaccines, which were also adapted to the prevailing virus variants last year.

Hospitalizations caused by SARS-CoV-2 infections were prevented by 39.2 percent through the Covid-19 vaccination. At the same time, there were 29.3 percent fewer emergency room visits among the group vaccinated against SARS-CoV-2. A subgroup analysis showed that individuals aged 65 to 75, as well as those with cardiovascular diseases, diseases affecting the brain vessels, chronic kidney disease, immunocompromised individuals, and those with lung diseases particularly benefited from the vaccination.
