My daughter had one dose of the chicken pox vaccine when she was one or two.  She then developed a small case of the chicken pox from the vaccine.  At age 12 she had the shingles.  Nine months later, my 5 year old neighbor had the shingles.  She too had a small case of the chicken pox before she was one, before they gave her the vaccine.  Unlike my daughter, she had the second shot before entering public school.  I am concerned that this vaccine is casing shingles.
