After a year of lockdowns, we're back to a more 'normal' year — with 'waned' immunity
Quote:
Off the back of a year of COVID-19 infections, social distancing and lockdowns, we're back to a more "normal" year — but with "waned immunity".
Experts say that because in 2020 we were not exposed to viruses and infections — other than COVID-19 — at the usual rate, many people have become so-called "naive" to them.
This is most apparent in the recent "large resurgence" of respiratory syncytial virus (RSV) — a virus that typically affects infants and young children.
