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 okay, the BCG vaccine takes 4 to 6 weeks to develop pus, and it's not yet...Doctor's answer:
The opinion is correct. According to regulations, after receiving the BCG vaccine, there should be a local scab for 4 weeks before another vaccination can be administered at the same site. However, the baby's vaccination site 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 includes redness, swelling, infection, pustule formation, rupture, and scabbing. Generally, the scab will fall off after about 3 months, leaving a scar at the site. It is recommended to perform a PPD test for the baby after 3 months to confirm successful vaccination.
Care Instructions: If there are blisters or pus at the vaccination site, keep it clean. Avoid tight clothing. If pus oozes out, gently clean it with sterile gauze or cotton. Do not squeeze it. The scab will naturally fall off within two to three months.
