"Worthless" may be about the best one can say about them. At this point, they appear to be contributing to actual harm.
In September 2020 -- at which time no one in the U.S. had been vaccinated -- there were 19,138 deaths involving COVID. Last month (i.e., September 2021) -- at which time millions of people in the U.S. had been vaccinated -- there were 58,996 COVID deaths. That is an increase of 208%, comparing September 2021 to September the year previously.
This trend towards increasing numbers of COVID deaths started this past August 2021. Data for the month of October 2021, while not yet complete, indicate that this trend is continuing.
Well...that’s alarming. Haven’t heard that.
