Vaccination of Adults with Cancer Guideline ASCO Guidelines

Dr. Lisa Law and Dr. Randy Taplitz share the latest evidence-based recommendations from ASCO on vaccines in adults with cancer. They discuss recommended routine preventative vaccinations, additional vaccinations and revaccinations for adults undergoing HSCT, CD19 CAR-T treatment, or B cell-depleting therapy, guidance for adults with cancer traveling outside the U.S., and recommendations for vaccination of household and close contacts of adults with cancer. Dr. Law and Dr. Taplitz also share their insights on the guideline, including the importance of this guideline for adults with cancer and their clinicians, future advances in research, and current unmet needs.

Brittany Harvey: Hello, and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. 
My name is Brittany Harvey, and today, I am interviewing Dr. Lisa Law from Kaiser Permanente and Dr. Randy Taplitz from City of Hope Comprehensive Cancer Center, authors on “Vaccination of Adults with Cancer: ASCO Guideline.”
Thank you for being here, Dr. Law and Dr. Taplitz.
Dr. Lisa Law: Thank you.
Dr. Taplitz: Thank you, Brittany.
Brittany Harvey: Before we discuss this guideline, I'd like to take note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Taplitz and Dr. Law, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. 
So then, to dive into the content, here first, Dr. Taplitz, can you provide a general overview of both the scope and purpose of this guideline on vaccination of adults with cancer?
Dr. Randy Taplitz: Yes, so people with cancer often experience a compromised immune system due to a variety of factors. This includes chronic inflammation, impaired or decreased function of the hematopoietic system, and treatments that compromise their immune function. Because of this, people with cancer are at a higher risk for infection, including with vaccine-preventable diseases. Also, response to vaccines in patients with cancer may well be affected by this underlying immune status, and their anticancer therapy, as well as the severity of the underlying malignancy. The purpose of vaccination in this group of patients is to prevent infection or to attenuate the severity of the disease when infection cannot be fully prevented.  
This ASCO review builds on a 2013 guideline by the Infectious Diseases Society of America, or IDSA, and uses what’s called a systematic literature review of 102 publications between 2013 and 2023. This includes 24 systematic reviews, 14 randomized clinical trials, and 64 non-randomized studies. The largest body of evidence in these studi
