This is stated in a joint press release of the organizations.

“WHO and UNICEF have warned of a worrying decline in the number of children who receive the vaccines necessary for life in the world,” Interfax quoted the press release as saying.

According to experts, this jeopardizes "hard-won progress in the distribution of a wide range of vaccines for even more children and adolescents."

Earlier, the WHO reported that the number of cases of coronavirus in the world almost reached 13 million.
