How does getting vaccinations affect the way I age?

Dr. Michael Roizen, MD
Internal Medicine
Unfortunately keeping your vaccinations current makes a RealAge (physiologic age) difference of just one hundred twenty-six days (if you are an adult involved in a mutually monogamous relationship). Not much, you're thinking. True, and yet those one hundred twenty-six days can be pretty important. That's because this figure is misleading. Many of the diseases for which we have vaccines available, such as diphtheria or measles, rarely afflict adults. However, when they do, the effects can be devastating. Other diseases that are more common, such as the flu and pneumonia, are rarely fatal, so the mortality risk is low. Because RealAge calculations take into consideration both the number of people affected and the mortality risk, the RealAge differential for immunizations is somewhat skewed to a smaller effect, because if everyone gets the vaccinations, the chance of anyone getting this disease is extremely small.
