The SARS-CoV-2 vaccine provides cross-protection to the unvaccinated: Study
Along with vaccinated individuals, the SARS-CoV-2 vaccine also protects the unvaccinated people within the locality, according to a study published in the Nature Medicine journal.
COVID-19 is a disease caused by a novel strain of coronavirus, named SARS-COV-2. In COVID-19 'CO' refers to Corona, 'VI' for the virus, and 'D' for disease. Formerly, this disorder was also referred to as '2019 novel coronavirus' or '2019-nCoV.' In the year 2021, many countries worldwide developed vaccines against the SARS-COV-2 virus and have conducted mass vaccinations in their respective countries.
A ton of recent studies have put forth the significance of mass vaccination in controlling the spread of the deadly COVID-19 virus, by providing the necessary protection to the people receiving either one or two doses of the vaccine. Also, a study has pointed out the effectiveness of the BNT162b vaccine from Pfizer–BioNTech in preventing not only the vaccinated but also the non-vaccinated in the community. However, it is not possible to observe this putative effect, especially during the highly fluctuating spatiotemporal epidemic changes.
