CVS Pharmacy complaint: Refusal to give vaccine resulting in delay of chemo treatment

I scheduled a Covid booster and shingles vaccine online as per my doctor’s instructions before I was supposed to start Ruxience infusions. As per the FDA guidelines anyone who is immunocompromised is eligible to receive the shingrix vaccine regardless of the age requirement. When I arrived for my appointment the pharmacist refused to administer the vaccine stating that I didn’t meet the age guidelines. I explained to him that it was per my doctor’s instructions as I am scheduled to start infusion therapy. I offered to pay out of pocket if it was an insurance issue. He stated again that I was ineligible because of age…which is 100% incorrect. He then told me that he refused to administer the vaccine but that I could get the Covid booster. I opted to go to another pharmacy all together as this was completely inaccurate and I needed this vaccine to start my treatment.
I then contacted my doctor who ed that I was in fact eligible for the vaccination. She then told me that because I wasn’t able to get the vaccination I would need to delay treatment. Now because of this pharmacist’s complete incompetence and outright refusal to give the vaccine due to ignorance of the FDA guidelines I must delay chemotherapy treatment. Who knows at what cost. I should really be contacting an attorney as well. This is absolutely unacceptable and probably unethical as well.
