What the hell is an "enhanced" shot? Does it come with the microsoft/apple/google tracking chip or a happy ending or something?

I guess it's one of the "high-dose" versions for you old dudes.

How are high-dose flu vaccines different from other flu vaccines?

Compared with standard flu vaccines, high-dose flu vaccines have more of an ingredient that boosts the immune response. The ingredient is a flu virus antigen called hemagglutinin. High-dose flu vaccines may have 3 to 4 times as much flu virus antigen as the standard flu vaccine.

There's also a flu vaccine that boosts immune response using an ingredient called an adjuvant. These shots have the same amount of flu virus antigen as a standard flu shot. But the adjuvant helps the body respond to the vaccine. This type of flu shot is called an adjuvanted flu vaccine.

High-dose and adjuvanted flu vaccines can help people have a stronger immune response against influenza.

For this reason, high-dose and adjuvanted flu vaccines are recommended for people age 65 and older. These vaccines also may be available to people ages 18 to 64 who have had solid organ transplants.
