你以为疫苗无敌的吗?
How effective is BCG vaccination?The BCG vaccine is made from a weakened strain of TB bacteria. Because the bacteria in the vaccine is weak, it triggers the immune system to protect against the disease. This gives good immunity to people who receive it without actually causing the disease. The vaccine is 70 to 80% effective against the most severe forms of TB, such as TB meningitis in children. It's less effective in preventing respiratory disease, which is the more common form of TB in adults.
她应该是有接触到,自己免疫力不足,结果中了,又错过最佳治疗时间。 我不相信她没有打BCG
