The Vital Role of Vaccines for Americans Over 60: Protecting Health and Independence

As we age, our immune systems naturally weaken, making adults over 60 more vulnerable to serious infections that can lead to hospitalization, disability, or even death. Vaccines are a cornerstone of preventive healthcare, offering robust protection against diseases that disproportionately affect older adults. For Americans over 60, staying up to date with recommended vaccines is critical to maintaining health, independence, and quality of life.

Below, I explain the key vaccines for this age group, their benefits, and their recommended priority based on current CDC guidelines, tailored to the U.S. context.

Shingles Vaccine (Shingrix): Very Strongly Recommended
Shingles, caused by the reactivation of the varicella-zoster virus, affects about 1 in 3 older adults, with risks increasing after age 50. The painful rash can lead to postherpetic neuralgia, a debilitating nerve pain condition that can last months or years. Shingrix, a two-dose vaccine for adults 50 and older, is over 90% effective at preventing shingles and its complications. In 2018, only 34.5% of Americans over 60 had received a shingles vaccine, underscoring the need for greater uptake. Given its high efficacy and the significant impact of shingles on quality of life, Shingrix is very strongly recommended for all adults over 60, even those who’ve had shingles or the older Zostavax vaccine. This vaccine has also shown promise in reducing dementia and possibly Alzheimer’s. Medicare and most insurance plans cover it, making access straightforward.

One word of warning: many people become briefly sick after the second dose. In my case, I slept for 40 hours straight and woke up just long enough to cancel all my appointments before going back to sleep. Don’t plan on doing anything after your second dose!

Pneumococcal Vaccine: Very Strongly Recommended
Pneumococcal disease, caused by Streptococcus pneumoniae, leads to pneumonia, meningitis, and bloodstream infections, which are particularly severe in older adults. About 1 in 20 pneumonia cases and 1 in 6 bacteremia cases in those over 65 are fatal. The CDC recommends a single dose of PCV20 or PCV21 for all adults 50 and older, with PCV15 followed by PPSV23 as an alternative for some. These vaccines reduce the risk of invasive pneumococcal disease by up to 85%, protecting against hospitalization and death. Given the high morbidity and mortality in this age group, pneumococcal vaccination is very strongly recommended. Medicare Part B covers these vaccines at no cost for those 65 and older, removing financial barriers.

Influenza (Flu) Vaccine: Strongly Recommended
The flu can be devastating for older adults, leading to complications like pneumonia and heart issues. Each year, flu causes thousands of hospitalizations and deaths among those over 65. High-dose or adjuvanted flu vaccines (e.g., Fluzone High-Dose, Fluad) are designed specifically for adults 65 and older, offering stronger protection than standard-dose vaccines. Annual vaccination reduces flu-related hospitalizations by about 40%. Due to the seasonal nature of flu and its severe impact, an annual flu shot is strongly recommended. Most insurance plans, including Medicare, cover it at no cost. While the flu shot isn’t perfect, it’s a small price to pay to help improve your odds against something bad happening.

COVID-19 Vaccine: Recommended
COVID-19 remains a significant threat, particularly for older adults, with those over 65 accounting for the majority of related deaths. Vaccination, including boosters, significantly reduces severe outcomes, though public skepticism persists. Those previously vaccinated against COVID-19 have greater protection than the unvaccinated, with studies showing up to 90% reduction in hospitalization risk for boosted individuals.

In my view, it’s an individual choice. I don’t think you need to get boosted every year, but it depends on your immune system, exposure, frailty, etc. If you live in a senior community, you should probably be more protected. I do think the vaccine helped a lot of older people become less sick, but I also think far too many people under 65 were vaccinated and many boosters may not be the solution. Discuss concerns with a healthcare provider to weigh benefits and risks.

RSV Vaccine: Recommended for Some
Respiratory syncytial virus (RSV) can cause severe respiratory illness in older adults, particularly those 75 and older or those 60–74 with risk factors like heart or lung disease. Vaccines like Arexvy, Abrysvo, or mRESVIA reduce severe RSV outcomes by about 80%. The CDC recommends RSV vaccination for all adults 75 and older and for those 60–74 with specific conditions. For others over 60, it’s optional based on shared clinical decision-making with a provider, given varying risk levels.

Tdap/Td Vaccine: Recommended for some

Tetanus and diphtheria are rare but serious, with tetanus causing painful muscle spasms and diphtheria leading to respiratory complications. Adults over 60 need a Td booster every 10 years, with a one-time Tdap dose (including pertussis protection) if not previously received, especially if around infants. These vaccines are highly effective, and tetanus prevention relies solely on vaccination. If you’re often out doing physical things in environments where you may get a puncture would, I would recommend it. If you’re in a senior community, I doubt it is worth the trouble. Td/Tdap coverage is typically available through Medicare Part D or insurance.

Summary
The situation with vaccines is similar to hormone therapy for women: Not enough people are getting the protection they need, mostly because they don’t think about it. For adults over 60, vaccines prevent debilitating illnesses that can erode independence, strain finances, and burden caregivers. They reduce healthcare costs by lowering hospitalization rates and protect communities by limiting disease spread. Most vaccines are covered by Medicare or insurance, and side effects are generally mild (e.g., soreness, fatigue). Consulting a healthcare provider ensures a tailored vaccination plan, accounting for health status and prior doses.
