According to Professor Nikolai Petrovsky and others the risks to children of COVID19 are much less than older people. The main argument in vaccinating children is to stop transmission of the virus. A key question then is whether transmission of the virus is less in vaccinated people. If less there is an argument to vaccinate children. And that could be with a protein- based vaccine called COVAX-19 that is now being trialed with 17,000 people. Professor Petrovsky says protein-based vaccines have a history of being safer for use in children.
