The World Health Organization has unveiled new recommendations regarding vaccines for specific viruses. These include administering three doses of the polio vaccine to all infants in countries where fewer than three doses are currently used, aiming for coverage over 90%. It also recommends a single dose of the human papillomavirus (HPV) vaccine for girls aged 9 to 14 to prevent cervical cancer, and the use of one-fifth of a dose of the yellow fever vaccine in situations where supplies are scarce. The guidelines emphasize vaccinating populations at high risk of monkeypox, organizing rapid vaccination campaigns against diphtheria in areas with low coverage, and underscore the importance of confirming the efficacy of new vaccines through robust clinical trials before widespread adoption.
