There are no special risks or side effects from extra chickenpox vaccine.
The incubation period (the time from exposure to the disease to developing the first symptoms) is 14 to 16 days.
Usually a skin rash that look like pimples or mosquito bites that develop into blisters and then into open sores, sometimes this is accompanied by a low grade fever. After 2 - 4 days symptoms should start to disappear, unless your child has a weakened immune system then a more serious rash, fever or more serious infections.
Live vaccines given before the first birthday often do not provide lifelong immunity.
Shingles is pretty rare in kids and teens who have healthy immune systems. Shingles is caused by the same virus that causes chickenpox.It's easy to pass the virus on to people who aren't immune to chickenpox (like people who haven't already had chickenpox or gotten the chickenpox vaccine). The difference is that if they get infected, they won't get shingles.
