The Centre has said it will provide a fresh supply of vaccines for the said age group on June 10.
She requested the Union government during the daily vaccine bulletin to provide vaccines for the group as several people will soon be due for their second dose.
"It is becoming a serious issue as a lot of people in the 18-44 group are nearing their date for the second dose. We are also hearing reports that people are travelling 100-200 km to Meerut, Bulandshahr to get their shots because there are no vaccines in Delhi," Atishi said.
She added that when youth gets vaccinated in large numbers, the 45+ age group will also be encouraged to come out.
"Seeing the youth getting vaccinated will also reduce their hesitancy to vaccinate," she said.
On Saturday, a total of 57,990 doses were administered, including 42,742 first doses and 15,248 second doses.
So far 56,51,226 doses have been administered in the city, including 12,84,000 people who have been fully vaccinated.
For the 45+ age group, the city has a stock of 5,84,370 vaccines.
After receiving a new stock on Friday evening, the national capital has 21,850 Covaxin doses for the 45+ age group while 5,62,520 doses of Covishield are available.
