National studies show a connection between COVID vaccination and reduced domestic infections in Sweden
As members of society increasingly acquire COVID immunity through vaccination or previous infections, people without immunity to COVID-19 have a significantly lower risk of infection and hospitalization. It shows a national study done by researchers at Umeå University in Sweden.
“This result strongly suggests that vaccination is important not only for personal protection, but also to reduce infections, especially within the family.dangerous “Environment for communication”, says Peter Nordstrom, professor of geriatrics at Umeå University.
There is extensive research showing that vaccines significantly reduce the risk of COVID-19. However, little is known about the effects of vaccination on the transmission of the virus in high-risk environments such as within the family. This is intended for researchers at Umeå University to investigate in new research.
In this study, researchers found a dose-response relationship between immune population and risk in each family. infection Hospitalization of a non-immune family. Specifically, non-immune families had a 45-97 percent lower risk of infection and hospitalization as the number of immune families increased.
The survey is a national registry-based survey of more than 1.8 million individuals from more than 800,000 families. The researchers combined register data from the Swedish Public Health Agency, the National Board of Health and Welfare and Statistics Sweden. Authority Monitor statistical data. In the analysis, the researchers family Members who are immune to COVID-19 and at risk of infection and hospitalization for non-immunized individuals. The researchers explained the difference in age, Socio-economic status, Clusters within the family and some diagnoses that have previously been identified as risk factors for COVID-19 in the Swedish population.
Vaccination seems to help reduce infections and reduce the risk of infection for individuals. This not only reduces the risk of serious illness in more people, but also presents new problematic variants. And the risk of starting taking it is also minimized. As a result, regional, national, and global impacts have resulted in many people being vaccinated, says Umeo University Geriatrics Medicine. Marcel Barin, doctoral student and co-author of the study, said.
