Ask the Doctor Question:
I took the Johnson and Johnson COVID vaccine, and it is now time for my booster. Should I take the same J&J booster, or should I do the new technology and get a Moderna? Any studies available yet? (I have CLL but have not required any treatments, still in Watch and Wait.)
Answer: Per the CDC guidelines, you can now mix and match vaccines. We would highly recommend that you speak with the CLL expert physician managing your care regarding this topic. Anecdotally, we have heard reports of many CLL patients choosing to switch COVID-19 vaccine manufacturers without difficulty.
