Whether a pregnant woman has definitely overcome chickenpox can only be determined by a blood test. By taking blood from a doctor, the blood sample will be analyzed and the level of antibodies will be determined through the analysis. If the antibodies reach the specified level, it is possible to confirm that the woman has overcome chickenpox. The level of antibodies is increased by vaccination, but vaccination is not recommended during pregnancy. Vaccination is recommended for adults who have not yet gotten over chickenpox, as well as for women who are planning to become pregnant.\r
