Chicken pox or flea bites?

Just recently I got a new puppy I'm not sure if he has all his shots my cousin played with him and he got some itchy bumps after but they went away around my house they're is fleas and I'm sure he's gotten some but recently I've been getting all these rashes and a few have a liquid inside I've never had the chicken pox but I also haven't had no fever like sympthoms or nothing could it be chicken pox or an allergic reaction to flea bits ?
