Patient's question:
What is the reason for the slight redness and swelling in the child's left arm? Is it left over from getting vaccinated?Doctor's answer:
Hello, according to your description, the redness and swelling on your child's left arm suggests that this is the site where the vaccine was administered. You can consult whether it was the Bacillus Calmette-Guérin (BCG) vaccine. About 2 weeks after vaccination, local redness and infiltration may occur. If it subsequently becomes purulent and forms a small ulcer, it typically takes 8 to 12 weeks to form a scab. Generally, no treatment is required, but local hygiene should be maintained to prevent secondary infection.
