People fully vaccinated and dying of covid are the source.
"According to the latest figures from the CDC on May 10, there have been
32,543,257 reported cases of COVID in the U.S., of which
578,945 people have died. That’s a rate of 1.8% — a higher rate compared to the data we have on breakthrough infections. "
"The figures on breakthrough infections are real — in fact, there are now more than 9,000 recorded cases, which have resulted in 132 deaths, less than 1% of the total. But it is widely misleading to use these numbers as evidence that vaccines are dangerous and ineffective, and the post leaves out crucial facts about breakthrough infections."
578,945 vs 132. Good luck.
