Parental Guidance: Research suggests kids may have COVID-19 immunity predating pandemic
While researching new studies around the globe, I came across this interesting piece of information on Nature.com that was published in November. Nature carries a compilation of research from around the world and this one research said scientists at the Francis Crick Institute in London analysed blood samples—from adults and children—who had not been infected with the new virus and found they contained antibodies. Nature says: “Scientists have found antibodies that recognize SARS-CoV-2 in the blood of people who have never caught the virus. Children are particularly likely to harbour such antibodies, which might explain why most infected children have either mild illness or none at all.” The blood samples in question were collected before Covid began to wreak havoc worldwide or just when it started to, which means that immunity to it already existed in some people.
