So our daughter had the BCG at 3 days old - it took 6 months for it to turn into a (very big and painful) red lump and within a few days it had become full of greeny yellowy puss. Took her to the hopsital (we were staying in Spain for a week) and whilst they were checking her they burst the lump by accident. They said it was an infection from the vaccination but on taking her to the GP back in Blighty he said it was the normal reaction. 5 days on and puss is still leaking from the wound but our GP was less than helpful in how to keep her wound clean and what to do with it since there's a hole of about 0.5cm in diameter on her arm. Anyone help with what to do? Ta.
