New Delhi: There are unlikely to be any adverse effects of two different doses of anti-covid vaccines being administered to a same person, NITI Aayog (Health) member VK Paul said. However, he said that as per the protocol, it is important to stick to the one vaccine regime, but if the mix-up has happened, it is not a cause of concern. His remark came in the backdrop of an incident that took place in Uttar Pradesh's Siddharthnagar district bordering Nepal where as many as 20 people were administered with two different doses of vaccines.
"If second dose of different Covid vaccine is given, any significant adverse effect is unlikely, but we need more scrutiny," Dr Paul said in a media statement on Thursday.
The 20 people from Audadhi Kalan village, aged above 45, were given a shot of Covishield (AstraZeneca) in early April, but then got the Bharat Biotech's Covaxin as part of their second dose in May.
Based on studies, some countries have allowed mixing up of Covishield first dose with Pfizer and Moderna for better efficacy. However, India has been following same vaccine's two-dose regimen.
Meanwhile, Dr Paul further said that India should be prepared to give on crore Covid-19 jabs a day, adding that the country will have enough doses available in next three weeks.
"We'll have to prepare to give one crore doses in a day. It will be possible in few weeks, we will have to prepare. We made possible 43 lakh doses in a day. We should bring it up to 73 lakh in next three weeks. We should make a system to achieve it," he told ANI.
According to Health Ministry, a total of 20,57,20,660 people have been vaccinated so far in the country, including 29,19,699 who were administered vaccines in the last 24 hours.
