摘要
目的 分析宁波市儿童水痘突破病例流行病学特征.方法 通过宁波市儿童预防接种信息系统和中国疾病预防控制信息系统记录匹配,纳入宁波市2011-2016年出生儿童接种水痘疫苗(Varicella vaccine,VarV)后截至2020年12月31日发病的水痘突破病例,比较1剂次和2剂次VarV接种儿童水痘突破病例报告发病率.结果 宁波市2011-2016年出生儿童水痘突破病例总报告发病率为142.86/10万(920例);其中接种1剂次、2剂次VarV儿童分别为590.82/10万(520例)、71.94/10万(400例),平均发病年龄分别为3.63±2.01岁、6.30±1.60岁,累计发病率分别从接种后第18个月的11.53/10万、4.79/10万快速上升至第36个月的140.00/10万、58.76/10万.结论 宁波市儿童水痘突破病例发病率随着VarV接种时间的推移呈上升趋势,接种2剂次VarV显著降低了水痘突破病例发病率.
Abstract
Objective To analyze epidemiological characteristics of breakthrough varicella in Ningbo children.Methods We enrolled children born during 2011-2016 who had varicella breakthrough infections after receiving varicella vaccine(VarV)that occurred on or before December 31,2020.We used case records from the China Disease Control and Prevention Information System matched with vaccination records from the Ningbo Children's Vaccination Information System.We compared reporting incidences of breakthrough varicella for 1-dose and 2-dose VarV vaccination.Results The overall incidence of reported breakthrough varicella was 142.86 per 100 000 population(920 cases).Incidences per 100 000 for 1-dose and 2-dose VarV were 590.82(520 cases)and 71.94(400 cases),respectively,with average ages of onset of 3.63±2.01 and 6.30±1.60 years.Cumulative incidences per 100 000 increased rapidly from 11.53 and 4.79 at 18 months to 140.00 and 58.76 at 36 months after 1-dose and 2-dose vaccination.Conclusions The incidence of breakthrough varicella among Ningbo children increased over time after VarV vaccination;2-dose VarV vaccination significantly reduced breakthrough incidence.
