...but wait for the line at the end of the Medium.com article:
"Even if the association between mRNA vaccines and RVO truly exists, the effect size is not huge, and it’s unlikely to outweigh the benefits of vaccination, especially in populations at risk of severe Covid."
The ending line really solidifies the insanity of the vaccination proponents; at this point what benefits does the vaccine grant that would offset the risk of blindness? I also recall a anecdotal story of an eye doctor being able to tell if someone is vaccinated by looking into their eyes via a camera. Scary stuff.
i've read anecdotally that ophthalmologists/optometrists have been able to tell the vax'd just by clotting just during basic eye exams.
no refunds.
