@marilynredder2367, I want to clarify the information that you are referring to. It can be confusing.
The Evusheld treatment is not a Covid19 vaccine. It is a pre-emptive shot for immunosuppressed patients who do not get protection from the Covid19 vaccines due to our immunocompromised systems. It is given in a clinic setting and needs to be approved and ordered by care provider. It is 2 shots in the buttock, one immediately after the other. I am not sure if those who get it will need a repeat later. We are watching and waiting. I will share the link to CDC infoemation at the end of this post.

The other 'shot' is the Covid19 Vaccine which can be administered by local physician, pharmacy, health dept., etc. After the 1st shot (I believe this is what you have just received) there is a 2nd shot which ifs followed by the booster series (2)
NOTE_As a transplant patient who is immunosuppressed, we need to get 3 Covid19 vaccines before beginning the booster series (currently 2).

CDC has a website that explains tis better than I did:
-Stay Up to Date with Your COVID-19 Vaccines
https://www.cdc.gov/coronavirus/2019-ncov/vaccines/stay-up-to-date.html

Here is information about who should get Evusheld in addition to COVID-19 vaccination.
