“免疫接种不足和麻疹易感儿童人数创历史新高，表明计划免疫服务在COVID-19大流行期间遭受了严重破坏，”美国疾控中心主任罗谢尔·瓦伦斯基（Rochelle P. Walensky）说。
“The record number of children under-immunized and susceptible to measles shows the profound damage immunization systems have sustained during the COVID-19 pandemic,” said CDC Director Dr. Rochelle P. Walensky.
“Measles outbreaks illustrate weaknesses in immunization programs, but public health officials can use outbreak response to identify communities at risk, understand causes of under-vaccination, and help deliver locally tailored solutions to ensure vaccinations are available to all.”
In 2021, nearly 61 million measles vaccine doses were postponed or missed due to COVID-19-related delays in immunization campaigns in 18 countries.
