I'm involved as a volunteer with Rob Relyea's site where people can search for Evusheld and other covid treatment drugs. (It's here: https://rrelyea.github.io/evusheld/).

In the course of working on it I have run across a few things that might be useful to people trying to get it. So here are some slightly random Evusheld resources.

-HOW MUCH IS AVAILABLE: The site I linked above tells you how much Evusheld is available at each site that has some, and in each state as a whole. Many doctors mistakenly think there is almost none available, and it can only given to those with extreme immune suppression. There actually is a fair amount available in most states. And it is being distributed extremely slowly. Only about 1/3 of the amount that has been sent to the states since January 1 has been given to patients. The rest is sitting on pharmacy shelves. If your doctor thinks there is very little available, you can show them the numbers on this site. Or you can find the exact same numbers (though in a less user-friendly way) on the US government site, which is at https://covid-19-therapeutics-locator-dhhs.hub.arcgis.com

-GUIDELINES INFO SOURCE: The guidelines in the Emergency Use Authorization say Evusheld is to be given to people who are moderately or severely immune suppressed, but give few other details. Here is a site that spells in out detail who meets those criteria: https://www.upmc.com/coronavirus/immunocompromised-patients
This is not a government agency, just some sort of large health service organization in Pennsylvania. Still, they sound reputable and their info makes sense. If a doctor is not sure whether you qualify, can can show them the info on this page.

-SITES IN 4 STATES THAT ACTUALLY ADVERTISE THAT THEY GIVE EVUSHELD. I believe all but one of them require that your doctor send them an order, but if your doctor will not do that it is worth contacting them and asking whether they have a doctor who will evaluate you and prescribe it. (Of course, you would need to bring documentation of your illness and meds.).

--Massachusetts: This page tells about getting Evusheld in Mass.: https://www.mass.gov/info-details/evusheld-tixagevimabcilgavimab#i-think-i’m-eligible-for-evusheld.-how-can-i-get-it?- Most of the sites they list are institutions where you have to be a patient of the institution to receive Evusheld there, but Mass. site also mentions a chain of mobile clinics called Gothams that take all comers.

—Pennsylvania. This place looks promising. https://www.upmc.com/services/infusion-services

—Michigan: This places look promising: https://www.sparrow.org/covidcare/sparrow-covid-19-outpatient-treatment/.
So does this place: https://www.solvhealth.com/search?l=42.742393,-84.521811,Lansing,%20MI&patientType=adults&appointmentTime=&reasonForVisit=Evusheld&providerType=urgent_care&isCovidTestRelatedSearch=false&shf=false&requestedServices=gmYrng

—Florida: This place is especially promising: https://www.icaremm.com/evusheld-covid19-treatment-miami-florida While they have a link up saying “Get on the wait list,” when I called them they had Evusheld available immediately. For people near them, in the Miami area, they would actually bring the shot to your home (for a fee, of course). Others need to go to one of their centers, which are near Miami. I called and asked whether they required a doctor’s order, or would evaluate someone themselves and give Evusheld if someone met their criteria, and they said they would evaluate the person themselves (said the charge for the evaluation would be about $150, and they could take insurance). I must admit they sound like they play a bit fast and loose, but the person I spoke with was quite pleasant and reasonable and not at all pushy.

—A way of hunting for Evusheld providers who are open to the public (as opposed to only giving it to patients in their hospital or whatever): Try going to Google and entering “how obtain Evusheld in [your state name]”. That is how I found the places above, including the Florida one.

—If your state has some kind of hotline for Covid help and information, try calling them and just explaining the situation: You are sure you qualify for it, but your doctor is unwilling to write an order for it. I know of at least one person who got Evusheld this way.

—And this may be worth looking into: If you go to Twitter and search for Tweets mentioning Evusheld, you will find a couple people advertising to locate it for you. Obviously this is a bit sleazy, and I’m sure they charge for the service, but if I were desperate I would consider it. I do find it believable that someone like a pharmacist who knows a bunch of other pharmacists & clinics would be able to source some in a legal way. As I said, there is actually quite a bit of Evusheld in most states, sitting on pharmacy shelves. And some pharmacies have little doc-in-the-box clinics affiliated with them, and it might be that some of these docs would be willing to write an order for Evusheld. If you try this, be cautious and suspicious and ask for references.

Wishing you all the best! If I find out more, I will come back and tell you.
