The proportion of children (one-year-old) vaccinated with three doses of diphtheria, tetanus toxoid and pertussis fell nearly 6% between 2019 and 2021, leading to an estimated 25 million children missing at least one dose in 2021. Similarly, the coverage of the three doses of pneumococcal conjugate vaccines stagnated at this level from 2020 to 2021. Similarly, coverage of the two doses of the measles vaccine remained at approximately the same level from 2020 to 2021. The human papillomavirus vaccine has remained relatively low since its first introduction, with a 10% decrease in coverage between 2019 and 2021.
