Case in point: I have just moved out of the UK last week, and to my surprise, Google is slowly starting to return better and better search results. I (suspected) I had two flareups of herpeses after both my pfizer vaccines when I was there, so I searched then on Google, zero, whole result pages filled with nhs links and other websites with copy-pasted content from nhs and the likes (90% telling me to go see a doctor...). I was going crazy, joking with friends that the vaccine might not be what they're telling us it is, given the wide range of 'undocumented' side effects I got from it.
Now that I'm searching from Moldova, actual first result was a paper documenting two doctors with herpes zoster after vaccination. Apparently it does happen, from both the vaccine and the infection. Guess I'm not crazy.
