coronaviruses, enhance the body’s immune response to SARS-CoV-2, both during natural infection and following vaccination, showed research published in Science journal.
The study was done by researchers from Charité – Universitätsmedizin Berlin, the Berlin Institute of Health at Charité (BIH) and the Max Planck Institute for Molecular Genetics (MPIMG).
The researchers also report that this ‘cross-reactive immunity’ decreases with age. This phenomenon may help to explain why older people are more susceptible to severe disease and why their vaccine-induced immunity is often weaker than that of young people.
The researchers in an earlier study indicated that individuals with no prior exposure to SARS-CoV-2 have ‘T helper cells’ that must
