What Is the Evidence for Vaccines?

This ministry is dedicated to the proposition that science and faith are friends, which requires looking at evidence. We mean objective physical evidence, not tabloid claims or religious tantrums. So, what is the evidence for vaccines? Vaccines can indeed cause an allergic reaction, but so can eating wheat in some individuals. In fact, eating wheat products has killed a few people.

In 2022, children in South Sudan were dying from measles. The government began a vaccination campaign in 2023, and medical workers there now tell us that measles is almost totally unknown. The Center for Global Development in Washington, D.C., says that in the past 50 years, the measles vaccine saved nearly 94 million lives. The oldest weekly peer-reviewed medical journal in the world is The Lancet, founded in 1823 in England. In May 2024, the Lancet said vaccines against the 14 common pathogens have saved 154 million lives over the past five decades – six lives every minute. Vaccines have reduced global Infant mortality by 40%.

The shining light of vaccines is the smallpox vaccine, which British physician Edward Jenner developed in 1796. Before that time, smallpox killed millions of people, and others were left with scars, infertility, blindness, and crippling. Abraham Lincoln and Mozart both survived smallpox. A worldwide vaccination campaign by the World Health Organization eradicated smallpox in 1977.

The big issue in South Sudan right now is malaria, which killed 7000 people in 2022. Children are especially vulnerable to malaria, and parents are doing extraordinary things to get their children vaccinated. What is the evidence for vaccines? They help save lives.

God did not cause these diseases. Human error, ignorance, greed, and selfishness all increase them, but God has given us tools to combat horrible diseases. I remember when polio was killing my friends and classmates in the 1950s and how eager I was to get the Sauk vaccine, which stopped that plague. Christians must be on the front lines of ensuring that vulnerable people can get vaccinations.
