Much of the focus is on a mutation in the spike protein, that is shared by the UK and South African variants.
Authorities expected 1,200 to turn up, anticipate better numbers in coming days
Ernakulam, which reported the highest numbers in Covid cases during most of last year, heaved a sigh of relief as the massive vaccination drive commenced on Saturday.
Covid vaccination drive kick-started in 11 centres in the district in strict adherence to Covid protocol and the presence of a government observer.
A total of 78 healthcare providers were administered the vaccine at the institute, and of them, 40 took Covishield and 38 took Covaxin.
Healthcare workers, as a category, would include doctors and paramedical personnel. The first phase is expected to be completed within 7-10 days.
The vaccination drive to combat Covid-19 began at 133 designated centres in the state on Saturday, marking the beginning of an effort to immunise more than three crore people.
Every individual in the state will be administered the Covid vaccine, Health Minister K K Shailaja has said.
While some districts saw very few beneficiaries turning up to take the jab, there were also technical glitches with the CoWIN app which resulted in some delay in starting the drive.
The first to get the jab across the state were Group D workers who had in some way or the other contributed in the fight against the pandemic.
Just as there were glitches with the Co-WIN portal during the dry run, Day 1 of the Covid vaccination launch saw technical issues once again.
Adverse reports on the efficacy and side-effects of Covid-19 vaccines kept listed beneficiaries away from vaccination sites on Day 1 of the Covid vaccination drive on Saturday.
Addressing the media on Saturday, Yediyurappa said, “In Karnataka, we have identified 243 centres, and in each centre, 100 people will get vaccinated in a day.
“We were filled with fear when we were handling the body of the first victim in the district. The virus was still new and we were not sure if PPE kits were enough to protect our lives.
The first shot of the vaccine was administered to Dr K Senthil, State president of TN Government Doctors Association.
