I was Dx-ed with PMR in early 2020. It took a year for me to get a diagnosis. I am still dealing with residual associated problems. My case came on as a result of a vaccination so I will always be careful about the timing of all future vaccinations. My guidelines are I must be off all non-maintenance drugs for at least 30 days. Non-maintenance drugs are things like a one-week course of antibiotics for an infection, or an antiviral for a mouth ulcer, or eyedrops for an eye problem. My maintenance drugs are my thyroids and blood pressure pills - that' s about it. I will only take one vaccination at a time, I never doubled up pre-PMR so why do it now? And I wait 2-4 weeks between vaccinations depending on work works best at the time. Last year I needed Flu, Covid and RSV this year only Flu and Covid. If you read up on what vaccines do to your body to built immunities it only makes sense to take a break between vaccinations.
