NYBob: That might be a case of a poisoner. On another topic, the next round of COVID boosters will be given in senior-citizen facilities--nursing homes, assisted-living places, etc.--in October. Over the summer, I know of a facility where there was an outbreak of COVID. So what good do the boosters do? They keep the seniors out of the hospital. But do they weaken the seniors' immune system, making them more susceptible to the virus.
