Do not take a BCG vaccination if you are using antibiotics, steroids or chemotherapy. According to Medicine Net, the BCG vaccine may interact with such drugs.
Some side effects are to be expected within 72 hours of getting a BCG vaccine, states Medicine Net. However, call your doctor immediately if you suspect an infection from the BCG vaccine, or if you experience excessive nausea, cough, fever, vomiting or blood in your urine after the 72-hour period.
According to Medicine Net, it is possible to spread the virus from the BCG vaccine to others within six hours of receiving it. To prevent this, use bleach in the toilet when you urinate during this time.
