Children of mothers who took a covid vaccine:
I plan to have children with my gf which got the vaccine, I need your help

I want the best for my children and the idea that something bad comes from the mother to the children which could then spread to millions of people after millions of years is getting me anxious

I'm not a schizo, I didn't get the vaccine because I'm healthy, barely go out and I don't like what I'm seeing here https://www.swissmedic.ch/swissmedic/en/home/news/coronavirus-covid-19/covid-19-vaccines-safety-update-6.html
I also don't like the idea that something from the vaccine could interract with my children when he/she is smaller than whatever particle we're talking about, if that's possible (non 0 chance)

But what is the worst case scenario?
What have been your experience?
Is being anxious over this reasonable or not?
Please any biologists or similar help me understand the potential risks and find the truth

thank you
