Based on the medical literature, here's what you need to know about your newborn's BCG injection site abscess:

What's Happening

A draining abscess at the BCG injection site is a recognized complication, occurring in approximately 1 per 1,000-10,000 vaccinated infants. This can happen even with correct intradermal injection technique. The fact that it has drained on its own is actually favorable.

Management

Park's Textbook of Preventive and Social Medicine (a standard reference used in India and globally) provides clear guidance:
For injection site abscess: "Incise and drain; antibiotics if bacterial."
However, the WHO guidance clarifies that this depends on whether infection is present:
  • If draining spontaneously and appears clean (sterile): No treatment is typically required. Allow it to continue draining naturally. Keep the area clean and dry.
  • If signs of bacterial infection are present (purulent discharge, increased redness, warmth, swelling, fever, or foul odor): Require antibiotics. The drainage itself should be cultured if possible to guide antibiotic selection.

What You Should Do Now

  1. Observe the drainage - Is it clear/serous or purulent (thick, yellow/green)? Is there fever, spreading redness, or increasing swelling?
  2. Keep it clean - Gentle cleaning with sterile gauze or saline. Avoid tight dressings that trap moisture.
  3. See your pediatrician if:
    • The discharge becomes purulent or foul-smelling
    • Signs of infection develop (fever >38°C, spreading redness, increased warmth, swelling beyond the site)
    • The abscess doesn't improve over 1-2 weeks after drainage
    • Lymph nodes in the armpit (axilla) become enlarged and draining (this indicates BCG lymphadenitis, a different complication requiring specialist evaluation)
  4. Avoid antibiotics empirically - These are only needed if bacterial infection is confirmed or strongly suspected.
Most sterile BCG abscesses heal spontaneously over weeks to months with local care alone. At 40 days old, your infant is still within the expected timeframe for BCG site reactions (typically 2-12 weeks post-vaccination).
Bottom line: If the drainage is clear and your baby shows no signs of infection, reassure care with close observation is appropriate. Contact your doctor promptly if signs of bacterial infection develop.

The discharge was scanty purulent there is no fever

Given that there is scanty purulent discharge but no fever, this suggests a mild bacterial component. Here's your management approach:

Current Situation Assessment

The presence of purulent (even if scanty) discharge without fever indicates:
  • Mild local bacterial colonization/infection rather than systemic infection
  • Your infant is handling it well clinically (no fever = good immune response, not systemic spread)

Management Recommendations

1. Antibiotics are indicated (since purulent discharge is present):
  • Topical antibiotic is usually sufficient for mild cases:
    • Mupirocin ointment (Bactroban) 2% applied 2-3 times daily, OR
    • Fusidic acid ointment if available
    • Cover lightly or leave open to air after application
  • Oral antibiotics (if purulent drainage continues or worsens despite topical treatment):
    • Amoxicillin-clavulanate (Augmentin): standard choice for mild skin infection in infants
    • Dosing: consult your pediatrician based on your baby's weight
2. Local wound care:
  • Gentle cleaning with saline or sterile water 1-2 times daily
  • Pat dry thoroughly (moisture promotes infection)
  • Allow to air dry when possible
  • Avoid occlusive dressings
3. Monitoring:
  • Continue daily observation for signs that infection is worsening
  • Watch for: increasing purulent discharge, spreading redness, fever, swollen armpit lymph nodes
  • If improving after 3-5 days of topical antibiotics: continue current management
  • If worsening or not improving in 5-7 days: escalate to oral antibiotics
4. Follow-up:
  • Review with pediatrician in 3-5 days to confirm improvement
  • Most cases resolve within 2-4 weeks with topical antibiotics

Key Point

The absence of fever is reassuring—this is localized, not systemic. Start with topical antibiotics and close observation. Escalate only if signs of worsening infection appear.
Contact your pediatrician today or tomorrow to confirm diagnosis and get a prescription for topical antibiotics if they haven't already been recommended.
