The data comes from a study in Israel and claims that for every 20% of people vaccinated more, the number of positives among the unvaccinated decreases by double

A new study just published in Nature Medicine highlights how mass vaccination has a protective effect even against the unvaccinated: as the percentage of immunized people (with the Pfizer-Biontech vaccine) increases, the number of infections among the unvaccinated drops dramatically.Researchers from the Technion Israel Institute of Technology in Haifa, Maccabi Healthcare Services and Tel Aviv University analyzed vaccination logs and test results (PCR) for coronavirus in 177 communities , geographically separated and with different vaccination coverage rates, for the period between December 6, 2020 and March 9, 2021.
In doing so they found an evident correlation between the percentage of vaccinated (1, 37 million people aged 16 to 50 who have received at least one dose of Pfizer vaccine) and the number of infections among the unvaccinated population (under 16). In particular, the data suggest that every time the percentage of vaccinated increases by 20%, the cases of coronavirus positivity among unvaccinated people decrease by double.
According to scientists, research confirms that vaccinated people have less likely to get infected, and even when they do, they have a low viral load with little chance of passing the infection on to others.
As the immunity conferred by the vaccine increases among the population, in short, the unvaccinated are less likely to meet infected and contagious people.
The data, the authors emphasize, do not hold account of the immunity that may have been acquired naturally and, although encouraging, are preliminary and will need to be confirmed by further studies.
