Why Flu Shots Are Crucial for Seniors
Older adults have weakened immune systems, a process known as immunosenescence, making them more vulnerable to the flu and its complications, such as pneumonia, bronchitis, and worsening existing conditions. As people 65 and older experience a greater burden of severe seasonal flu disease, vaccination is highly important for this age group.
Regular vs. Specialized Flu Shots for Seniors
While seniors can receive a standard-dose flu shot, it's not the preferred option. The Advisory Committee on Immunization Practices (ACIP), which advises the CDC, recommends specific injectable flu vaccines for adults 65 and older that provide a stronger immune response.
The Preferentially Recommended Vaccines
There are three main types of flu vaccines recommended for seniors over the age of 65:
- High-Dose Vaccine (Fluzone High-Dose Quadrivalent): This vaccine contains four times the standard antigen amount to create a more powerful immune response. It has proven more effective than standard shots in preventing flu-related hospitalizations in this age group.
- Adjuvanted Vaccine (Fluad Quadrivalent): This standard-dose vaccine includes an adjuvant, an additive that boosts the immune response, making it more effective for seniors.
- Recombinant Vaccine (Flublok Quadrivalent): Created using cell culture technology, this highly effective vaccine does not rely on eggs for production and is another preferentially recommended option for older adults.
Comparison of Flu Shot Options for Seniors
The options for individuals 65 and older, including standard, high-dose, adjuvanted, and recombinant flu shots, have different features regarding recommendations, primary goals, antigen strength, side effects, availability, and key benefits.

What to Do If a Preferred Vaccine Isn't Available
If a preferentially recommended vaccine is not immediately available, the CDC and ACIP advise that older adults receive any age-appropriate flu vaccine instead of going unvaccinated. This is because the benefits of some protection far outweigh the risks of waiting for a specific, preferred vaccine that may not be available.
Timing is Everything for Seniors
For older adults, getting vaccinated too early in the season (e.g., July or August) can lead to waning immunity by the time flu season peaks in late winter. The Centers for Medicare & Medicaid Services (CMS) and CDC recommend that older adults get their flu shots in September or October to ensure maximum protection throughout the peak of the flu season.
Considerations for Underlying Health Conditions
For older adults with underlying health conditions, such as diabetes, heart disease, or chronic lung disease, getting a flu shot is especially critical. These conditions can be exacerbated by influenza, potentially leading to severe complications. The enhanced protection offered by high-dose, adjuvanted, or recombinant vaccines is particularly beneficial for this high-risk group. Additionally, the flu shot can be administered concurrently with other recommended vaccines, such as the pneumococcal vaccine, which protects against a common flu complication, pneumonia.
Conclusion: Making an Informed Choice
While seniors can receive a regular flu shot, specialized vaccines offer superior protection for the aging immune system. In consultation with their healthcare provider, older adults should prioritize getting a high-dose, adjuvanted, or recombinant flu vaccine. However, if only a standard-dose vaccine is available, it should be taken without hesitation, as some protection is better than none. For further information, visit the CDC Flu Information website.
