Prime Minister Narendra Modi on Monday called the vaccine as the biggest weapon in the fight against COVID-19 and urged doctors to encourage more and more patients to get the jab.

In a virtual interaction with the country's leading doctors on the pandemic situation and vaccination progress, he also noted that COVID-19 is spreading rapidly in tier-2 and tier-3 cities this time, and asked them to connect with their colleagues working there and give them online consultations to ensure that all protocols are followed correctly.
