Covid Vaccine and Breastfeeding

My work is requiring that all employees to get the vaccine. Now normally I am all for vaccinating but being that this one is so new and I have a baby that’s 4 weeks old and breastfeeding, I am afraid there could potentially be side affects. Currently there isn’t any research but I am wondering if any nursing moms have had the shot yet or not? Also notice any changes in yourself along with lactation?
