Sid is hearing a lot of talk about how to stay healthy, which leads him to ask lots of questions about what can make a person sick and what he can do to keep from getting sick. In the special episode "Getting a shot: You Can Do It!," Sid and his friends learn the basic science behind germs, viruses and vaccines. When it’s vaccination day at Sid’s school, Sid and his friends are a little apprehensive about getting a shot. Thankfully, a very special nurse will be giving the kids their vaccination—Sid's Grandma! Grandma, Teacher Susie, Mom and Dad all do their part to make vaccination day a fun learning experience filled with music, games and lots of laughs.
