World Health Organization and United Nations International Children's Emergency Fund have warned that some 80 million babies around the world are at higher risk of diseases like diphtheria, measles, and polio.

According to a vaccine institute of UNICEF, vaccine campaigns have been disrupted in at least 68 countries due to Covid-19.

The organizations said 27 countries have postponed campaigns of vaccinations that protect against measles, while more than a dozen have paused some polio vaccination programs.
