The second wave of Covid, is in which the numbers are skyrocketing, is hitting younger people and children - unlike the first round when the elderly, and those with co-morbidities were seen to the most vulnerable sections. Data from the Union health ministry shows 79,688 children have been infected in the five states affected worst by the virus. Currently there is no vaccine for children. A testing of AstraZeneca vaccine of children in the UK has been suspended over reports of the vaccine being linked to blood clotting, which has led to seven deaths in the European nation.
