Covid-19 infection less likely if family members are fully vaccinated: Study

The greater the number of family members with immunity against coronavirus disease (Covid-19), either from a previous infection or full vaccination, the less are the chances of other non-immune individuals in the household contracting the infection and hospitalisation, a new nationwide study in Sweden has revealed.

The study findings identified a dose-response link between the number of immune members in one family and the risk of infection and hospitalisation in the non-immune family members. It found that the non-immune individuals had a 45% to 97% lower risk of infection and hospitalisation as the number of immune family members increased, the researchers said, reports HT.

The results of the study, Peter Nordstrom, professor at Sweden’s Umea University said, strongly suggest that Covid-19 vaccination is “important not only for individual protection, but also for reducing transmission, especially within families, which is a high-risk environment for transmission.”

This latest research – which is different from several studies available on how Covid-19 vaccination significantly curtails the risk of contracting the virus, as claimed by the researchers — is a registry-based study. More than 1.8 million people from over 800,000 families in Sweden participated in the study.
