Yep.
This is like saying " everyone is saying to get more exercise but I overdid it and tore a hamstring, so exercise is actually bad for you".
I concur.
My wife did the same thing and i got both flu and covid booster same day- sore arms sure, but no issues. Basically we did what our Medical Doctor advised.
However, on the other hand, after getting my first shingles vac (or was it my 2nd?), I was sick as a dog for almost a day- really bad chills. But then- fine. So, yeah, some flu like symptoms occur. They tell you this.
Those are a scam.
Incidentally if you google “mycotoxin-eliminating candles - scam?” the SDMB shows up as a top search item.
Okay, I had a bad reaction- about 12+ hours of feeling sick with bad chills. Compared to a life of incurable pain if you actually get Shingles- the trade off is extremely good.
Just prepare yourself- make sure extra blankets are near, etc. Really it wasnt so bad afterwards.
