Covid Vaccine and Breastfeeding?

I've spent the past 3 hours reading articles and studies and stats and all kinds of things on getting vaccinated while breastfeeding and I can't find anything that definitively says its safe or not. I've read that there have been very few adverse effects and/or events with bf mothers and their babies but I'm so worried.

I got my first dose of the Pfizer-BioNTech vaccine on Saturday and me and my 7 month old have been fine. I talked to his dr a couple weeks ago about getting the vaccine and he recommended that I go ahead and get it seeing as my son and I are healthy and reassured me that other bf mom and thier babies that he sees have gotten it and they were just fine. He had a doctor appointment today to get up to date on his shots and I made sure I mentioned to his dr that I had gotten the vaccine and he even said it was good and might help my son not get sick.

One of my friends posted this link and it just has me freaked out

Any bf moms out there got the Pfizer-BioNTech vaccine? What was yours and your babies experience with the first and second doses and any boosters you got? I just need some reassurance and more information.
