Global vaccination rate in one-year-olds 1980-2021, by vaccine

Vaccination rates among one-year-olds have risen drastically in the past four decades, with global coverage for some of the most important vaccines increasing from below twenty percent in 1980 to above eighty percent in 2021. Several vaccines introduced on a larger scale in the 1990s, such as the Hepatitis B vaccine, have increased from just one percent coverage to well over two thirds coverage today. As many infants receive multiple vaccines at one time, or as barriers to healthcare access are lifted, this has meant that global coverage trends have been fairly similar for the most common vaccines, and that coverage for newly developed vaccines has grown relatively quickly (such as the Hepatitis B and Inactivated Polio vaccines).

Recent backsliding

The COVID-19 pandemic marked the first time in recent history where coverage among one year olds dropped for multiple vaccines. In some cases, global coverage fell by as much as five or six percent for vaccines including diptheria/pertussus/tetanus, hepatitus B, measles, and polio. This backslide has been attributed to a variety of factors, such as weakened healthcare systems in less developed regions, the spread of misinformation surrounding vaccines, disruptions due to containment measures, supply chain issues, and the diversion of medical resources. It had been hoped that 2020 would be an anomaly, and that figures would return to their previous trajectory in 2021, but rising malnutrition and and weaker food supply to the poorest regions has exacerbated this further.
