Which vaccine is recommended for adults over 65 years of age?

The pneumococcal vaccine is particularly significant for adults over 65 years of age due to the increased risk of serious pneumonia and other complications associated with pneumococcal infections in this age group. Older adults are more susceptible to pneumonia, which can lead to hospitalization and even death. The vaccine works by stimulating the immune system to recognize and fight off the Streptococcus pneumoniae bacteria, which are responsible for many cases of pneumonia, meningitis, and bloodstream infections.

While influenza, shingles, and hepatitis B vaccines are also important for older adults, the pneumococcal vaccine is specifically emphasized due to its direct role in preventing pneumonia and related severe consequences. The Centers for Disease Control and Prevention (CDC) recommends that all adults over 65 receive the pneumococcal vaccine to help protect this vulnerable population.
