Rav Eliyahu Brog: COVID Crisis - Middah Kineged Middah Of How We Persecuted Our Unvaccinated Brethren
I experienced so many "Aha!" moments while reading the transcript. The actual shiur is available on the same page as the transcript.
Note: Just to be transparent about where I'm coming from: I'm not an anti-vaxxer in general; I & my children have received the standard vaccinations over the years. However, research has caused me to be undecided regarding the measles & mumps vaccines, see no reason for the chicken pox or diphtheria vaccine, and am highly suspicious of the COVID-19 vaccine.)
Thank you so much to Neshama of Going Home...To Yerushalayim blog for publicizing the above link (and also for all her investigative research into the whole topic).
