Melissa Castillo said:I've been wondering—why don't those childhood vaccination scars ever really fade away? Every single person I know has these deep pits or several indentations on their arms, and it seems like they just get wider over time. 🤦
What you're looking at are basically keloid scars, which are a standard reaction to the BCG vaccine used for tuberculosis. It’s a localized response. First, you get a blister, then a small nodule forms, and eventually, you're left with a permanent scar that stays with you for life. Honestly, I'd take a mark on my shoulder over contracting TB and dealing with scarred lung tissue any day. And I'm not quite sure what you mean by "deep pits." 😕
Anyway, if someone actually finds them bothersome, there are ways to fix it...
