Pneumonia is particularly deadly after a covid injection...
Stop with the misinformation already.
A Covid injection cannot cause Covid, as it only contains a single gene which tricks the immune system into producing antibodies. In order for someone to catch Covid, they have to be exposed to whole intact active viruses. And of course, the chance of catching severe Covid drops significantly after a Covid injection.
She probably had something we call "influenza-like-syndrome" or "ILI" which is caused by any number of viruses (but not influenza viruses). Since viral infections leave people more susceptible to catching bacterial infections, an ILI is what probably led to the deadly pneumonia.
