“Whenever schools reopened in the midst of the pandemic, I was hesitant to send my son. It will be a relief now that he has received the vaccine,” said Savita Devi, whose son was waiting to get the jab at a Delhi government school.
Some students referred to restrictions on travelling and said they did not want to miss out on activities because they are not vaccinated.
“This was long-awaited. The third wave is already here and considering how aggressive the second wave was, we were all afraid,” said Ritesh Ghosh, a 17-year-old student.

But there were some like Diksha Patel, 17, from Raipur in Chhattisgarh who required some counselling from her family and friends to overcome hesitancy.

"However, my mother and other family members spoke to me about the benefits of vaccination, especially in view of rising cases and a possible third wave," she told PTI.
