Is there risk in waiting for the same formulation of booster?

This content was current as of the date it was released. In science and medicine, information is constantly changing and may become out-of-date as new data emerge.

Ask the Doctor Question:

Pfizer is in the process of developing a booster shot that supposedly will be more protective against the Delta variant. I’m thinking of waiting for that booster rather than getting one now which is the same formulation as the original. I have little contact with the outside world, so I don’t think there’s much risk in waiting. What do you think?

Answer: Please do not wait. Things are changing so quickly. They may be “working on it” but who knows when something like that would get approved and/or if it would be effective against the prominent variant at the time of its release. You may have very little contact with the outside world like many of us do, but all it takes is that accidental contact with one person.

At this time, CLL Society is encouraging all chronic lymphocytic leukemia patients who received the Moderna or Pfizer vaccines to promptly arrange for a booster unless otherwise directed by their healthcare team.

We would encourage you to take a look at a couple of the articles we just wrote on this very subject. There is an official statement on the COVID-19 boosters for CLL patients, as well as answered some of the most common questions we have been receiving in a question-and-answer document. Here are the links for both of those articles:
