My hospital hasn't started flu shot clinics yet, but all the office staff are trained up on encouraging flu shots. There is a different version for older folks (65+, a good chunk of this board I imagine, so listen up) that my office doesn't have, that apparently provokes a stronger immune response in those patients. We refer those patients to their PCP. Not sure which of the two we have/will have. Previously we had the trivalent high dose, but I guess this adjuvant one is new for 2020 along with the quadrivalent high dose.

This was confusing to me, so let me try to clarify things.
Quadrivalent vaccines are designed against 4 strains of flu; trivalent vaccines are designed against 3 strains.
"Fluzone High-Dose Quadrivalent contains four times the antigen, the part of the vaccine that helps your body build up protection against flu viruses, then Fluzone Quadrivalent and other standard-dose inactivated flu vaccines. . . . In the United States, Fluzone High-Dose Quadrivalent is licensed only for persons aged 65 years and older." ("Four times the antigen" has nothing to do with "quad" in Quadrivalent. Apparently, Fluzone High-Dose Quadrivalent does not have the adjuvant.)
Apparently last year's high-dose shot was a trivalent vaccine; this year it is a quadrivalent.
"FLUAD and FLUAD Quadrivalent is a standard-dose, inactivated influenza (flu) vaccine, manufactured by Seqirus that contains an adjuvant. During the 2020-2021 influenza season, both trivalent FLUAD and FLUAD Quadrivalent will be available. Both of these vaccines are approved for people 65 years and older.....An adjuvant is an ingredient of a vaccine that helps promote a better immune response...... In the United States, FLUAD and FLUAD Quadrivalent are licensed only for persons aged 65 years and older."
So, [trivalent] FLUAD, FLUAD Quadrivalent, and Fluzone High-Dose Quadrivalent are 3 different vaccines, each licensed only for 65 years an older. The first two contain an adjuvant. The last contains 4x inactivated virus.
I didn't see a comparison on outcome or reactions to FLUAD or FLUAD Quadrivalent vs Fluzone High-Dose Quadrivalent. I didn't see any comparison of reactions of high-dose vs regular dose. (high-dose was more effective at reducing hospitalizations for seniors)
The CDC does not recommend any type of approved vaccine over another type (including
types other than these mentioned here). [ie, they don't recommend ones associated with fewer hospitalizations over ones with more hospitalizations].
Although most experienced little reaction, there was slightly more reaction to quadrivalent vs trivalent (for either regular dose or high-dose).
My company had a flu-shot clinic last week (that I didn't get to), done on campus by Safeway. We were told that "high dose" was available, but that could have been confused (by me) with any vaccine appropriate for 65+.
Safeway's web site mentions both Fluzone High-Dose and FLUAD Quadrivalent, so I think you're either going to have to check with a particular store to see whether they offer both or only one.
CVS only mentions the Fluzone High-Dose at their
flu shot page but the page appears be a hold-over from last year as they portray the high-dose shot as a trivalent vaccine.
"Rite Aid said that this year it is offering a quadrivalent flu vaccine, FLUAD trivalent vaccine with an adjuvant for patients 65 years old and older, high-dose Fluzone HD for older patients, and egg-free Flublok." (

Walgreens has a web page for flu shot options for older people. Apparently they offer the FLUAD trivalent, FLUAD quadrivalent, Fluzone High-Dose quadrivalent.
