Several Indian states had to postpone their vaccination plans for Covid-19 on Saturday due to supply shortages, the authorities said.

At least seven states or union territories were affected by vaccine shortages, as confirmed by CNN. These include the states of Telangana, Andhra Pradesh, Punjab, Gujarat, Madhya Pradesh, Gujarat, Maharasthra and the area of ​​the Union of Delhi, which also includes the Indian capital New Delhi.

India kicked off its vaccination campaign on January 16, initially focusing on health care and frontline workers, followed by those over 60 and those over 45 with existing health conditions. The drive was expanded to anyone over the age of 18 on Saturday.

India is facing a massive second wave of Covid-19 cases, with more than 400,000 reported in a single day on Saturday.

According to preliminary information in the press release, a total of 1,648,192 vaccine doses had been administered by 8 p.m., including 989,700 people who received the first dose and 658,492 people who received a second dose.

According to a press release from the Indian Ministry of Health on Saturday evening, 84,599 people between the ages of 18 and 44 received their first dose of a coronavirus vaccine. Fewer young people received vaccines because some states prioritized second doses and older people who hadn’t received their first dose.

By Indian time on Saturday evening, a total of 156,637,825 vaccine doses had been administered across the country since January. A total of 28,591,381 people received their second dose, which is just under 2.2% of the country’s 1.3 billion people.
