I’ll tell you what my oncologist told me at my top rated NCI hospital in the US. The vaccine is up to you and they will no longer push it on patients. The reason is because studies have come out linking it to autoimmune issues. There is nothing right now though that definitively links it to cancer. Anyway I have chosen to longer get it. I am not particularly susceptible to covid it seems since the one time I had it I didn’t even know it and have not had it since then. My oncologist was perfectly fine with my decision. I did my due diligence and got it three times and now that it’s been out long enough and we all have built up some antibodies I no longer feel like it’s a requirement to be a good citizen. So do it if you’re scared of getting covid. Don’t if you’re not.
