Hi, lathomasmd. I don’t think the immunotherapy boost is relevant to Avastin, although I am taking that as well. As I understand it, it applies to immune checkpoint inhibitors like Keytruda. However, I am not a doctor or scientist so please take my observations with a grain of salt. I’m happy to share my form of cancer. I have primary peritoneal cancer, which is essentially a form of ovarian cancer. My cancer is also high-grade serous cancer, as most ovarian cancers are. For what it’s worth, I am being treated at MD Anderson and my doctor there was in favor of me bringing all my vaccines up to date, including my covid and RSV vaccines. The only limitation as I understood it was I could not have live vaccines. You should obviously rely on your own doctor’s advice. P.S. I was also treated at Mayo Jacksonville and love the team there as well.
