Corona Vaccination (indicative picture)
In people without immunity against COVID-19, the risk of infection and hospitalization is very low. The reason behind this is the increase in the number of fully vaccinated family members having immunity against the virus. This information has been given in a nationwide study in Sweden. The research, published in the journal JAMA Internal Medicine, found a dose-response relationship between the number of immune people in each family and the risk of infection and hospitalization among non-immune family members.
Researchers say that the risk of infection and hospitalization in non-immune family members was 45 to 97 percent lower, as the number of immune family members increased. Professor Peter Nordstrom from Ume University in Sweden said, “These results show that vaccination is important not only for personal protection, but also for preventing the spread of the virus between people.” Especially within families, where the risk of spreading the virus is highest. Researchers said that there is a lot of research available about the effectiveness of the vaccine to eliminate the risk of COVID-19.
Data collected from Swedish government agencies
However, researchers say less is known about the effect of vaccination on the spread of the virus in high-risk environments, such as within families. The new research is nationwide, covering 1.8 million people from eight lakh families. The researchers gathered registry data from Sweden’s Public Health Agency, the National Health and Welfare Board, and Statistics Sweden. Statistics Sweden is a government agency that oversees statistical data. The study quantified the association between the number of family members who had immunity against COVID-19 and the risk of infection and hospitalization in non-immune people.
Vaccination stops the spread of virus
The study took into account age, socioeconomic status, within-house population, several diseases identified as risk factors for COVID-19 in the Swedish population. Researchers found that vaccination appears to not only help reduce a person’s risk of becoming infected, but also help reduce transmission. Umea University student Marcel Ballin said, “Vaccination prevents people from becoming more seriously ill. Due to vaccination, there is a lot of impact on the local, national and global level.
