来美国后，要求接种MMR的合并疫苗。
请问重复接种对身体会否有害？谢谢 | Y*Z
发帖数: 51 | 2 I think your doctor should check the titres of MMR first, then decide if
your baby needs MMR vaccine or not. If they asked your baby to get the
vacines, It is likely your baby really needs them. But I don't think it has
any bad effects because the second stimulation of the formed memory cells
and naive cells could lead to stronger response and then finally form more
memoery cell formation inside the body after elimination of the most
effector cells. I am just guessing so theoretically.
ask your doctor! | l**p

MMR美国孩子是要接种两次的，即使打过一次,第二次还是要打的，跟分开打,还是合打
关系不大 |
