On critical issue of the adverse effects of the vaccines, the health ministry said that across India, around 450 cases were reported so far. The officials also said that only three beneficiaries were required to be hospitalised due to the post-vaccination side-effects. The adverse effects range from mild headache to fever and nausea.
