New Delhi, Feb 13 (IANS) Despite testimonies and experience from peers, the vaccine hesitancy among healthcare workers has continued. The reason for the hesitancy is absence of "medical ritual" for adult vaccination in the country. "Barring a few exceptions, the vaccines were always administered to children till the Covid-19 pandemic arrived. Now, the introduction of vaccines have generated a lot of curiosity and raised inhibitions," said Chand Wattal, head of Department of Microbiology at the Sir Ganga Ram Hospital. The doctor who received his second dose on Saturday urged people to trust science as vaccines are safe. Around 1.9 lakh healthcare workers are scheduled to receive their booster shots of Covid vaccines on Saturday post a gap of 28 days after receiving the first jab of the two-dose inoculation regimen.
