PUNE: The national Adverse Effects Following Immunisation (AEFI) committee has urged states to ensure all side effects after Covid jabs are reported to the CoWin portal. The committee said there has been a drastic drop in reporting levels by states. States should tell vaccinators to report all events of concern occurring within 28 days of Covid-19 vaccination, committee head NK Arora said, adding that the reports should be uploaded on CoWin platform. Due to low reporting, India may be missing rare adverse events that could be of relevance to the community, Indian regulators and other countries, as some vaccines here are also deployed globally, he said.
