Naturally, as you age, your body naturally becomes weaker, making it harder to fight infections. Vaccinations are required for a number of reasons, like protecting against diseases such as the flu, COVID-19, tetanus, and shingles. They’re also used for other medical instances like allergies or diabetes.
While you receive most of them when younger, you may need booster shots. For example, the CDC recommends you get a Tdap (tetanus, diphtheria, and pertussis) or Td (tetanus, diphtheria) booster every 10 years.
