Patient's question:
Is there any bad interference in 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 okay, the BCG vaccine takes 4 to 6 weeks to develop pus, and it's still not...Doctor's answer:
The view is correct. According to regulations, after receiving the BCG vaccine, there should be a scab formation at the local site for 4 weeks before another vaccination can be administered at the same location. However, the vaccination site of the baby has not shown any local reaction again at this time, so it is safe to receive 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, the formation of pustules, rupture, and scabbing. Generally, the scab will fall off after about 3 months, leaving a scar at the site. It is recommended to conduct a PPD test for the baby after 3 months to confirm successful vaccination.
Aftercare: If there are pus bubbles or purulent discharge at the vaccination site, keep it clean. Avoid tight clothing. If pus is oozing, 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.
