I would go by the advice of your doctors and ultimately the decision is yours. There is no right or wrong decision as some claim there is. If your doctor's advice sets off red flags, question him or her and if they don't provide real answers and instead quickly recite CDC talking points, find another doctor. My point - if a doctor cannot answer questions which you have the right to know and simply rely on the same information that you can get from the CDC/FDA/NIH websites (their information leads to many questions), you might as well use Google for medical advice. Not a good idea and neither is taking medical advice from a CDC mouthpiece who is afraid of losing his/her medical license.
As far as shingles, I've had it twice. Both times I was denied a vaccine for it because I wasn't old enough (have to be at least 50-yrs old). I'm glad that I didn't take it when I was eligible because my doctor told me that each time somebody gets shingles, it's a much milder form than the previous infection. In my case, this was true. I'm sure this isn't the same experience for everybody; nothing ever is.
As far as big pharma, CDC and the FDA is concerned, I used to trust them completely. Once I started digging into the big tobacco lawsuits and watching and reading the junk science our own government was purposely putting out, I grew skeptical of these institutions and what motivated them. They did not have the health and well-being of society as their main motive. Heck, it wasn't even a motive at all, during those times. Money was. Politics was. Greed was. It still goes on today as big tobacco has spun a wide web into third world countries to capture young children. It's a disgusting, evil thing to watch and yet only concerned citizens ever voice opposition. Where is the CDC/FDA and our elected officials to reign this in? That's a rhetorical question.
Fast forward to January 2020 to present day. I gave the NIH, CDC and the FDA the benefit of the doubt but watched their messaging very closely. It wasn't adding up early on and is even worse today. It reminds me so much of big tobacco and the junk science that harmed so many. I do not trust anything coming out of our medical institutions right now and they will need to be gutted for me ever to consider trusting anything coming out of them.
COVID-19 is real. I had it and survived it. Over 1.5 yrs later, I'm still dealing with its effects. Thankfully, I live in a part of the country where I have access to some very good doctors who actually practice medicine and science. They're not afraid to dissent from the MSM narrative and help patients. They tell you the truth - the good, the bad, the ugly and even tell you when they don't have an answer. They treat patients and do not tell them to go home until you can't breathe and then go to the ER, like my former doctor did. Unacceptable. Demand better. No settling allowed.
While we live through these very difficult times in which our elected and appointed officials alike, have undermined basic trust in what is supposed to be the foundation of medicine in this country, it's ever-important to listen to all arguments with an open mind, play devil's advocate with yourself and see if your own conclusions still hold water. Or, has your bucket of knowledge sprung a leak or two? We owe it to ourselves and loved ones. We have to be an assertive participant in our own healthcare, even if that means offending arrogant physicians. The good ones, don't mind patients asking questions, even challenging questions and in fact, they expect it and they will give you their honest opinions.
