Interesting article on this topic.
Says yes, it’s safe. Though it notes a disclaimer that no studies on that topic question, so it makes me wonder if it really is safe?
Here’s article...

So... if you had participated in the LLS study for covid spike antibodies testing and say scored below the >250 marker (or say unfortunately yielded a zero score) and you were able to get a second vaccine (from a different brand), would you try it?
We CLLers are in a unique group when it comes to effectiveness (or lack of) covid vaccine protection.
I’d suggest check first with your CLL doc if you are contemplating that subject idea and see what she/he thinks for your situation ... and if it’s even doable in your area (allowable and/or if supply of vaccines are much greater than demand and they are having to discard them ... sad as that sounds given the world-wide need for vaccines).
