Struggling to book or reschedule a slot for the COVID vaccine? Read this

The second phase of the COVID-19 vaccination drive is for senior citizens and those over 45 years with comorbidities. Here is a detailed explainer of the entire process.

With Phase-II of COVID-19 vaccination having begun from March 1st, India’s fight against the pandemic is picking up pace. The first phase, which commenced on January 16th, saw healthcare workers (HCWs) and other categories of frontline workers (FLWs) eligible for vaccination. The second phase targets two categories:

1. Persons aged 60 and above  

2. Persons between 45 to 59 years of age who have a specified comorbidity (scroll down for list of comorbidities).

For monitoring and streamlining the vaccination process throughout the country, the government has created a digital platform, CoWIN (COVID-19 Vaccine Intelligence Network). CoWIN is designed to help keep track of vaccinations taking place across the country and share data with relevant agencies for monitoring and further decision making.
