这是《疫苗分歧》的一部分，这是一项更新的数据调查，调查美国可能失去麻疹消除国的地位，因为致命病毒卷土重来，儿童疫苗防御持续瓦解。
This is part of The Vaccine Divide, an updated data investigation into America potentially losing its measles-free status as the deadly virus roars back and childhood vaccine defenses continue to crack and crumble.
随着儿童疫苗接种率下降，感染麻疹等可通过疫苗预防的疾病的风险上升。使用这些地图查看你所在社区的儿童疫苗接种率。麻疹-腮腺炎-风疹疫苗对预防儿童和成人疾病非常有效。要控制社区内麻疹的传播，需要95%或更高的疫苗接种率。全国越来越多的县看到入园儿童的疫苗接种率低于这一保护阈值。
As vaccination rates among children go down, the risk of getting sick from a vaccine-preventable illness such as measles goes up. Use these maps to see the childhood vaccination rates for your community. The measles-mumps-rubella vaccine is highly effective in preventing illness in children and adults. To control the spread of measles in a community, a vaccination rate of 95% or higher is needed. A growing number of counties across the country are seeing the level of vaccination among children entering kindergarten drop below that protective threshold.
至少十年来，美国入园儿童中父母或照护者选择让他们不接种疫苗的儿童数量一直在稳步上升。
The number of children entering kindergarten whose parents or caregivers opt them out of vaccines has been steadily climbing in the U.S. for at least a decade.
