Routine vaccination ended in most countries by the early 1980s after smallpox was declared eradicated in 1980 (thanks to a global WHO campaign).
If you were born before ~1985 in Asia, Africa, Latin America, or Eastern Europe, you likely received it as part of national immunization programs.
In the U.S. and Western Europe, routine smallpox vaccination stopped earlier (U.S. ended in 1972 for civilians), so many younger people don’t have it.
Military personnel and some healthcare workers may still carry the scar from later vaccinations.
✅ Fun fact: Smallpox is the only human disease ever eradicated—and that scar is a living reminder of one of medicine’s greatest triumphs.

1. “It’s from a skin disease or burn.”
→ Truth: It’s an intentional vaccine reaction—not an injury or infection.
2. “It’s a TB test scar.”
→ Truth: The TB (tuberculin) test leaves no scar—just a temporary bump. The BCG vaccine (for TB) can leave a similar scar—but it’s usually smaller and less defined. The classic round scar is almost always from smallpox.
3. “It means I had smallpox.”
→ Truth: You were vaccinated against it—not infected by it. The vaccine used a related, harmless virus (vaccinia).
4. “It’s a tribal or cultural mark.”
