So my mom had to pick up my 6 year old cousin today and bring him to our house because one of his  classmates has COVID. My family is all vaccinated, except my brothers are still within 14 days of their last vaccination. My aunt and uncle, (my 6 year old cousins parents) who are currently at work, do not believe in the vaccine and refuse to get it stating *it's their freedom to choose and they don't want it* I'm worried now about my cousin getting it and exposing my family to it and I'm worried as the delta variant is hurting kids as well as adults. My mom is keeping him away from my brothers but I'm concerned.
