Vaccinated adults help protect unvaccinated children, studies find

New data from Israel Deployment of the fastest Covid-19 vaccine The world provides real-world evidence that widespread vaccination against the coronavirus can also protect unvaccinated people.

Israeli study, It was published In Thursday’s journal Nature Medicine, we took advantage of the fact that until recently Israel had only vaccinated people over the age of 16. Researchers have found that for every 20 percentage points increase in the proportion of vaccinated 16-50 years in the community, the proportion of virus-positive under 16 years unvaccinated has been cut in half.

“Vaccination benefits not only individual vaccinated people, but also those around them,” said a biologist, physicist, and data scientist studying microbial evolution and disease at Technion-Israel Institute of Technology. Said Roy Kishony. Dr. Kishony led the study with Dr. Tarpatalon, who is responsible for KSM, the Center for Research and Innovation in Maccabi, Israel. The first authors of this treatise are Oren Milman and Idan Yelin, researchers in Dr. Kishony’s lab.

Israel began vaccination of adults last December. Within nine weeks, almost half of the population was vaccinated.

Researchers investigated anonymized electronic health records of members of the Israeli HMO Maccabi Healthcare Services. We analyzed vaccination records and virus test results from December 6, 2020 to March 9, 2021. Vaccination and vaccination coverage.

For each community, we calculated the percentage of adults between the ages of 16 and 50 who were vaccinated at different times. They also calculated the percentage of PCR tests for children under the age of 16 who returned positive.

They found a clear correlation. As more adults were vaccinated in the community, the proportion of virus-positive children subsequently declined.

People who are vaccinated are much less likely to get the virus.the study I will also propose Even if a vaccinated person becomes infected with the virus, the viral load may be reduced and the infectivity may be reduced. As a result, as more and more people are vaccinated, unvaccinated people are less likely to encounter infected and contagious people.

“The results are consistent with the fact that vaccinated people not only make themselves sick, but also prevent the virus from infecting others,” said Dr. Kishony. “Such effects can be amplified over multiple cycles of infection.”

To Another recent treatiseFinnish researchers, who have not yet been published in scientific journals, have reported that after health care workers have been vaccinated, members of unvaccinated households are also less likely to be infected with the virus.
