There are two types of vaccines that the CDC recommends for people over 65: the high dose flu vaccine, also called Fluzone, and the adjuvanted flu vaccine, known as Fluad.

You can get both the high-dose and adjuvanted flu vaccines at your doctor's office, but you can also find the high dose vaccine at pharmacy clinics like CVS. .

The high dose flu vaccine has 4 times as many antigens as a regular flu shot, and is available specifically for people over 65. .

A study published in 2014 in the New England Journal of Medicine found that the high dose flu vaccine was 24% more effective in preventing flu in people over 65, compared with the standard vaccine.

Moreover, seniors who get the high dose vaccine are also less likely to be hospitalized for the flu.

Because the adjuvanted vaccine spikes your immune response, it may also have more side effects than the standard vaccine, including irritation at the injection site, muscle aches, and headache

However, the vaccine offers great protection for seniors – a study published in 2020 in the Journal of Infectious Diseases found that people over 65 who got the adjuvanted vaccine were less likely to be hospitalized for the flu, compared with those who got the standard vaccine
