COVID vaccines and kids: five questions as trials begin

Children rarely develop severe forms of COVID-19, and deaths from the disease are rarer still. On rare occasions — one estimate1 puts it at around one case in 1,000, although it could be even lower — kids who’ve experienced even mild infections can later develop a sometimes deadly condition called multi-system inflammatory syndrome in children (MIS-C). “I’m tired of seeing sick kids. I want to see them protected,” says James Conway, a paediatric infectious-disease specialist and vaccine researcher at the University of Wisconsin–Madison.
