Introduction

If a person carries syphilis antibodies for life and simultaneously has an abnormally elevated titer, shows signs of active infection, or has broken skin or discharge on the breast, breastfeeding is not recommended. During active infection, the pathogen may enter the infant's body through breast milk or broken skin, potentially causing infection in the infant. Proper treatment should be completed first, and breastfeeding can be reconsidered only after the condition has stabilized.

In general, women who are lifelong carriers of syphilis antibodies but have no active infection may breastfeed. However, breastfeeding is not recommended if there is an active infection. If in doubt, it is advised to consult a healthcare provider in advance. Detailed analysis is as follows:

If the individual is only a lifelong carrier of syphilis antibodies, with test results confirming consistently negative titers and no evidence of active infection, and if there are no breaks or inflammation in the breasts, breastfeeding is permissible. In such cases, there are no infectious pathogens present in the body, so the disease cannot be transmitted to the infant through breast milk. It is sufficient to maintain good breast hygiene during feeding.

However, if the person is a lifelong carrier of syphilis antibodies and also shows abnormally elevated titers or tests positive for active infection, or if there are open wounds or discharge in the breasts, breastfeeding should not be performed. During active infection, pathogens may enter the infant’s body through breast milk or broken skin, potentially causing infection. The mother should first receive standardized treatment, and breastfeeding can be reconsidered only after the condition has stabilized and further evaluation by a physician.

Women who are lifelong carriers of syphilis antibodies should undergo regular check-ups before conception and throughout pregnancy. A comprehensive medical assessment must be conducted before initiating breastfeeding. If any breast discomfort or changes in antibody titer occur during breastfeeding, nursing should be stopped immediately and medical attention sought.

If the mother has no discomfort such as fever, fatigue, or nausea after vaccination, and the roast duck is fresh, thoroughly cooked, and meets hygiene standards, consuming a small amount generally will not interact with vaccine components nor affect the immune response induced by the vaccine.
