Experts vouch for both Covishield, Covaxin

Secunderabad: Though the vaccination for healthcare workers began on January 16 and subsequently other frontline workers were also vaccinated, there were few takers for Covaxin compared to Covishield, the other vaccine which is part of the national immunisation programme for Covid-19. But, Covaxin, India's first indigenous vaccine for Covid-19, received a shot in the arm with Prime Minister Narendra Modi and Odisha Chief Minister Naveen Patnaik, among other senior politicians, choosing to take the jab on Monday.

Bharat Biotech was obviously upbeat over Monday's development. "Inspired and humbled by PM's remarkable commitment to build an 'Aatmanirbhar Bharat'. Yes, we all shall fight Covid-19 together and emerge victorious," the company said.

Bharat Biotech's Co-founder and Joint Managing Director, Suchitra Ella, also hailed Odisha Chief Minister's gesture.

The move to include Covaxin for national rollout even before publication of data from its Phase 3 trials came under criticism from some quarters. However, the regulator defended the decision, saying both the vaccines are totally safe.

Bharat Biotech has developed Covaxin in collaboration with the Indian Council of Medical Research (ICMR) - National Institute of Virology (NIV). The company said in case of any Serious Adverse Events (SAV), vaccine recipients will be provided medically recognised standards of care in the government designated and authorised centres/hospitals. The compensation for Serious Adverse Events will be paid by Bharat Biotech International Limited and if SAV is proven to be casually related to the vaccine. The compensation will be determined by the ICMR Central Ethics Committee, as appropriate.

According to data provided by the government in reply to a question in the Lok Sabha last month, only 16 of the 37 states and Union Territories had started to administer Covaxin as on February 9. Telangana had received 1,72,960 doses of Covaxin, second highest consignment among all states but it had the third lowest administration rate of the vaccine.

Telangana's Director of Public Health Dr G. Srinivasa Rao was the first person in the state to take Covaxin shot on February 8. However, not many frontline workers came forward to take the vaccine.

Experts also tried to dismiss talks of vaccine hesitancy. "Both vaccines are equally effective. There should not be any doubts in the minds of people," eminent breast cancer surgeon Dr P Raghu Ram said. "AIIMS director who is the main force leading the drive against the pandemic and all the staff in AIIMS have taken Covaxin. This speaks volumes," added Dr Raghu Ram.

Riyaz M. Khan, CEO, Continental Hospitals believes that misinformation may be creating reluctance among some people.

"Both the vaccines have gone through a robust testing programme and these are stable technologies. The inactivated technology used for Covaxin is the same technology used for almost all other vaccines. Covishield is based on vector-based technology. These technologies have gone through trials. To say that one is safe over the other may not be safe comparison," he said.

The reluctance at home is in contrast to the orders Bharat Biotech is receiving from various countries. Last week it announced that the Brazilian government has signed a deal to procure 20 million doses of Covaxin. Several other countries have evinced interest in buying covaxin.

Meanwhile, Ukraine's health minister Dr Maksym Stepanov last week visited Bharat Biotech's facility in Hyderabad's Genome Valley and discussed with the company officials the plans to procure Covaxin.

The Indian government has so far procured 5.5 million doses of Covaxin and issued a letter of comfort to company for another 4.5 million doses.
