I think we need to keep some perspective here, and realize in general only people with a problem come looking for answers on this forum. That means we do not know the experience of all PN patients - only those seeking support or information on Mayo Connect.

Also, it is important to know that those who get Covid, especially a severe case, are very likely to suffer aftereffects for months. Neuropathy is among those symptoms, even in people without prior history. Here is just one recent article, https://www.medpagetoday.com/meetingcoverage/aapm/92270

Here is another, written in March 2021 reporting new onset of neuropathy upon vaccination, resolved after a few weeks: https://onlinelibrary.wiley.com/doi/epdf/10.1002/mus.27251
John (@johnbishop) posted several others yesterday here https://connect.mayoclinic.org/comment/597475/

We each must make our own decisions, but if the incidence of long-lasting neuropathy or inflammatory flares after vaccination were common or widespread, I'm sure we would be seeing it in the news, and would be able to find many reports on the Internet. Look at the uproar caused by a handful of confirmed cases of blood clots after the administration of hundreds of thousands of J&J injections.

Finally, neuropathy after vaccine injections is not a new issue - VAERS has reports dating back to 2007 on neuropathy symptoms after injection. So today I took a dive into the VAERS reports to date on Covid vaccines specifically (86080 adverse reaction reports as of April 16th) Most reports of tingling or numbness (maybe 1% of reports) occurred within minutes of injection, with a few 36-48 hours post-injection (I looked at over 2000 records and found only 5) - I guess someone is going to need to some more digging to try to identify people who don't report - either themselves or through the health care system - to figure out how prevalent & how severe the reactions were.
