Chicken pox? I need someone with knowledge

Okay so I baby sat my nieces who, when they were with me, were diagnosed with chicken pox. We think it came from daycare. It was literally nothing for them when we kept anti itch stuff on them. They’re vaccinated and only acted sick for about 2 days but barely. Just needed some Tylenol, that 2 year old energy NEVER died down let me tell you. They just got real fussy at night when that wasn’t like them. Doctor said give them Tylenol and when we did they were fine and slept well.

I had to keep them longer to keep us all quarantined. My mom said I had chicken pox and was also vaccinated when i was their age so I couldn’t get it.

Can I still spread it though? My aunt is really needing help for personal reasons but she has a grand baby that isn’t even a year old and nope.

Just nope.

Just random info: vaccines do not make you immune. They give your body some idea of what to do when a disease or virus enters the body.
