Patient's question:
Is there any bad interference with getting another vaccine on the same arm? (I asked the doctor at the time, I said my child got the BCG vaccine on this arm, and it's been less than a month, the doctor said it's fine, the BCG vaccine takes 4 to 6 weeks to develop a pustule, and it's still not...Doctor's answer:
The opinion is correct. According to regulations, it is required to wait for 4 weeks for the local scab to form after administering BCG vaccine before vaccinating with other vaccines at the same site. However, the vaccination site of the baby has not shown any local reaction again at this time, so it is safe to vaccinate with the DTP or HIB vaccine. Please do not worry too much.Medical Advice: Most children will experience a local reaction again 3-4 weeks after receiving the BCG vaccine. This process involves redness, swelling, purulent vesicle formation, rupture, and scabbing. Generally, the scab falls off after about 3 months, and a scar may form locally. It is recommended to conduct a PPD test for the baby after 3 months to confirm successful vaccination.
Care Instructions: If there are pus blisters or purulent discharge at the vaccination site, keep it clean. Avoid tight clothing. If there is pus leakage, gently clean it with sterile gauze or cotton. Do not squeeze it. The scab will naturally fall off after an average of 2-3 months.
