Around 50 lakh people have self-registered for vaccination through CoWIN since the portal was opened for registration, Ram Sevak Sharma, chairman of the empowered panel on Covid vaccination, said on Tuesday.

"The actual numbers could vary up to 2 crore since the portal can register four beneficiaries with just one mobile number. We count only the mobile numbers, so I think the figures may be more than that," he said while addressing a press briefing of the Union Health Ministry. Earlier in the day, Union Health Minister Harsh Vardhan had told reporters that around 40 lakh people had registered on Co-WIN till Tuesday morning.
