Other than the part about reinfection there’s nothing surprising in what he said. Kind of like the baal shem stories- if you believe everything ditchek says you are a fool, but if you don’t believe it could have happened...
People are confusing herd immunity with eradication. It’s a fact that not every single person, even in the hardest hit communities has had the virus and is immune, especially those who took strict precautions. There’s no magic- if a stream of infected people coming from Florida, California, Israel etc. circulate in Lakewood and other communities, there will be some who get infected. The question is if it can lead to a massive outbreak, or if there is sufficient herd immunity to prevent secondary waves that continue to spread throughout the community, and we can expect a limited number of positives that remain fairly limited as people come out of quarantine and relax precautions. I believe the latter is true in Lakewood but the coming weeks should provide an answer.
