As an immunocompromised person, it’s likely her body wasn’t able to create (enough) antibodies from the vaccine. That’s the little reported secret...the vaccine was not tested on immunocompromised patients and even the CDC admits they don’t know if it will be effective for them. Of course, medical professionals and doctors just tell these folks to accept the risk and take the vaccine, because it’s not their life. In some cases, the vaccine is probably worse as it can flare an underlying condition.
The main stream press hasn’t reported on any studies of the covid vaccine being tested on patients whose immune systems are compromised (taking drugs because they have an organ transplant, taking drugs to fight cancer, etc). How effective are those vaccines for these patients? Yet the FDA approved it for everyone over 12 years old in the case of Pfizer. Maybe these vaccines should have had a warning label before they were approved for emergency use.
And that is the reason I use when asked why I haven’t been vaccinated. I just got off chemo in March & there was no way I was going to do it! Besides having a weakened immune system I don’t know if research has been done to see how the vaccine would interact with all the drugs. I feel sorry for the woman’s family. I’m sure they were hopeful the treatments were working & then have this happen....
