Is COVID-19 vaccination safe and effective for diffuse large B-cell lymphoma (DLBCL) patients? Dr. Jean Koff shares what’s currently known about COVID-19 vaccination for DLBCL patients and provides information about studies currently underway on immunocompromised patients.

A question that’s on many people’s minds right now is if the COVID 19 vaccination is safe and effective for people with DLBCL?
So, I don’t think we have any reason to believe that it’s not safe. We haven’t seen any signals that it is not safe. I think there are reasonable concerns that for patients who either have active lymphoma where the lymphoma may be impacting their immune system and the immune system’s ability to mount the response that you need to get immunity when you get vaccinated. But even more so patients who are receiving some sort of therapy, especially chemotherapy and immunotherapy. Those types of treatments actually may knock out the same normal bystander immune cells that help you mount that immune response when you get vaccinated.
And so, the concern there is that in those individuals either with active DLBCL or who are receiving treatment for DLBCL, that their immune systems might be somewhat compromised and not able to mount as robust of an immune response when they get vaccinated.
And by extension, the vaccine may not work as well to protect them against COVID as it would in somebody who doesn’t have a compromised immune system. But what I’m counseling my patients is that if they are not actively receiving treatment that impacts their immune system like chemo or immunotherapy, I am recommending that they go ahead and get the vaccine. Because to me the risk of COVID and COVID-related complications is very high. And the risk of complications from the vaccination is very low. And the protection that it offers – while we are not sure the level of protection that it offers in these special cases, some protection, if it does offer it is better than no protection. And the risk of immunization is low. We are actually doing the studies now at Emory.
In specifically lymphoma patients who get the COVID vaccine. Whether they have active lymphoma or getting treatment in lymphoma, we’re doing the studies now to take a look and see whether they’re able to adequately mount immune responses to the COVID vaccine. So, that we can better counsel our patients on how effective these vaccines will be.
So, once we have more mature data from our studies and from other centers, similar studies, we’ll be able to better estimate what the chances that the vaccine will be protective for an individual patient.
