其實一歲打完第一針, 最好唔好等到6歲先打第二針, 美國CDC Guideline 4歲就可打第二針
Chickenpox vaccine can prevent chickenpox.
Children who have never had chickenpox should get 2 doses of chickenpox vaccine at these ages:
1st Dose: 12-15 months of age
2nd Dose: 4-6 years of age (may be given earlier, if at least 3 months after the 1st dose)
People 13 years of age and older (who have never had chickenpox or received chickenpox vaccine) should get two doses at least 28 days apart.
