I had a client for yellow fever vaccination who is traveling to Congo to meet her husband, and wanted to know if it was safe for her to conceive during her 3 months stay?
Here is what the CDC has to say on this subject….
Yellow fever vaccination has not been known to cause any birth defects when given to pregnant women. Yellow fever vaccine has been given to many pregnant women without any apparent adverse effects on the fetus. However, since yellow fever vaccine is a live virus vaccine, it poses a theoretical risk. While a two week delay between yellow fever vaccination and conception is probably adequate, a one month delay has been advocated as a more conservative approach. If a woman is inadvertently or of necessity vaccinated during pregnancy, she is unlikely to have any problems from the vaccine and her baby is very likely to be born healthy.
That is what I told her, to wait for approximately 1 month before conception, but not to worry too much in case it happened sooner!
It must also be remembered that Breast Feeding is also something that needs to be possibly avoided / undertaken with caution in this situation.
