In 2007, doctors at the University of Oregon conducted what may be the best study of antibody levels to common infections. They followed 45 subjects for as long as 26 years, measuring their antibody levels to eight common pathogens: measles, mumps, rubella, Epstein-Barr virus, varicella zoster virus (chickenpox), diphtheria, tetanus and vaccinia (the cowpox virus that eradicated smallpox).

The results were remarkable. Antibody half-life — the time required for antibody levels to decrease by 50 percent — was 50 years for varicella zoster virus and, they estimated, more than 200 years for measles and mumps. The half-lives of tetanus and diphtheria were much shorter, 11 years and 19 years, respectively. That’s why, for example, it’s recommended you get a booster tetanus (bacterial,not virus) shot every 10 years.

An important caveat about these data is that immunity from natural infection may last longer than immunity from vaccination. As an example, individuals born before 1957, who grew up in a time when measles was “as inevitable as death and taxes,” may have more durable protection against measles than those who were born later and got the measles vaccine, which became widely available starting in 1963.
