Discussion Overview

The discussion centers around the availability and choice between Trivalent and Quadrivalent flu vaccines for the current flu season. Participants explore the implications of each vaccine type, including their protective benefits and cost differences, as well as logistical considerations for obtaining them.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant notes receiving the Trivalent vaccine and questions the commonality of the Quadrivalent vaccine this year, suggesting that the extra protection against both B strains might be beneficial.
  • Another participant shares their experience with insurance coverage for flu shots, indicating that it can be inconvenient to obtain the vaccine outside of regular doctor visits.
  • A participant references CDC information stating that a significant number of doses available this season will be Quadrivalent, but emphasizes that there is no preference for one vaccine over another among the approved options.
  • Concerns are raised about the cost difference between the two vaccines, with Trivalent priced at $25 and Quadrivalent at $35.
  • There is a mention of the logistical challenges in accessing vaccines, including long lines at free clinics.

Areas of Agreement / Disagreement

Participants express varying experiences and opinions regarding the availability and convenience of obtaining the Quadrivalent vaccine versus the Trivalent vaccine. There is no consensus on which vaccine is preferable or more widely available this year.

Contextual Notes

Participants reference specific data from the CDC regarding vaccine availability and recommendations, but there are no settled conclusions about the relative effectiveness or preference for the vaccines.

I try to get my flu shot early each year because of my medical work, and I got mine a couple of days ago. The pharmacy only had Trivalent vaccine, so that's what I got. But looking into the Quadrivalent vaccine, it looks like the extra protection (against both B strains) might have been worth trying to find a pharmacy that stocked it.

Do folks know how common it is to get the Quadrivalent vaccine this year versus the Trivalent vaccine? Are both typically available in most years, or is the Quadrivalent vaccine a newer idea?

My engineering company is setting up vaccinations for employees (a nice perk), and they are trying to decide which version to request. The Trivalent vaccinations are $25 each, and the Quadrivalent vaccinations are $35 each. Thanks for your thoughts.

Your insurance doesn't pay for them Berke? Thank you for reminding me I need to get mine, I guess I need to read up on them before I go.

I found this.

Four component vaccines are recommended to include the same three viruses above, plus an additional B virus called B/Phuket/3073/2013-like virus (B/Yamagata lineage).

They do, but it's pretty inconvenient. If you are in the doctor's office for a regular visit, they can give you the shot as part of the visit. Otherwise, they have free clinics on some Saturdays, but the line is around the building...

Thanks! :smile:
 
More from the CDC:
Of the 157 to 168 million doses of influenza vaccine projected to be available for the 2016-2017 season, manufacturers estimate that 96 million doses will be quadrivalent flu vaccine.
There is no preference for one vaccine over another among the recommended, approved injectable influenza vaccines.
