Second COVID vaccine after negative antibody test

[NormanNewYork]

My serology came back negative after the Pfizer vaccine. Has anyone gotten a non-mRNA vaccine after a negative serology? Did it make a difference

Norman, to my knowledge, there is no vaccination authorization available for another shot (or two shot series) to be given. There is work being done to develop/test a booster vaccination to be given later in the year, though nothing is set in concrete.

Thanks. A booster vaccine for Pfizer or Moderna is not going to help. The recent study from Israel show only a 16% success rate for CLL patients treating with irutinib. I emailed the researcher and they did not test the non-mRNA recipients nor have they suggested any follow up since Israel has herd immunity. England and Canada have mixed the two with no reported side effects. Given that I have no COVID antibodies i shouldn’t have a reaction regardless.

Hi Norman - I have been wondering the same thing and have been thinking of trying a J&J dose to see if it helps generate antibodies after having no success with the Pfizer. I can't see any harm in trying - what's to lose?
