No hysteria but there is a difference. Other vaccines have been tested at least 7 to 10 years. COVID vaccines have not gone through the regular testing procedures and the long term side effects are therefore unknown. That is why COVID vaccines have been approved for 'emergency use only'. The younger you are, the longer you risk long-term side effects and the less you risk from getting COVID. Thus, it is reasonable to be cautious with the COVID vaccine (unlike other vaccines) with younger people.

And yes, we consulted with my son's pediatrician (who studied, was certified and practiced in the US for awhile), and she advised us not to vaccinate our youngest. She (the pediatrician), herself, did not vaccinate her younger children.

I also got advice from my brother who was a department head at a University in Arizona in biology and has insights into this. Also, I myself am widely read (including biology and medicine) and I've helped researchers in the mathematical modeling of cell pathway signaling, in epidemiological models and models of antibiotic resistance in bacteria. So I do have insight on the mechanics and the level of understanding and uncertainties of studies similar to vaccination at the research level.

Finally, I understand why so many people distrust professionals. The reason is corruption where some professionals have been untrustworthy and especially pharmaceuticals have committed fraud and may have done so with the current vaccines (see https://www.bmj.com/content/375/bmj.n2635).

In my opinion, it is still important to trust the professionals. However, the culture of greed and corruption requires everyone not to blindly trust even the professionals.
