The effectiveness of the two-dose vaccination schedule of varicella is better than that of one dose, but the vaccination schedule and coverage of varicella varies based on provinces in the mainland of China and has differing effects.
Earlier vaccination of the first dose may reduce the varicella incidence, and improving the vaccination coverage rates of the second dose will further reduce the varicella incidence.
Taking the first dose of vaccination promptly at 12 months old and improving the coverage of second dose of vaccination may play an important role in varicella prevention and control in China.
