Vaccination Statistics

Vaccination prevents far more than missed needles, with global immunization impact estimated to avert 23 million deaths each year when full coverage is achieved. At the same time, gaps persist and can be stark, with 13.1 million children missing at least one vaccine dose in 2022 and 47% of countries still reporting DTP3 coverage below 90%.

By 2025, vaccine impact is still visible in the biggest swing point of all: routine immunization averts millions of deaths each year when coverage reaches targets, yet millions of children still miss at least one dose. In this post, we connect coverage gaps, dropout between shots, and measles and HPV outcomes to the real-world decisions that shape uptake, from reminder systems and school requirements to vaccine hesitancy and misinformation.
