BCG Vaccination

Totally normal! BCG usually forms a small bump or blister around 2-6 weeks after the jab. It might even become a small pus-filled sore, that’s all part of the normal process. Just keep it clean and dry, don’t squeeze or pop it. It’ll eventually crust over and leave a small scar. See PD if there’s a lot of swelling, redness spreading around the area, or baby has a fever.
