A small, round scar on an older person’s upper arm is usually from a smallpox vaccine. Millions of people born before the 1970s received this shot. It remains a visible sign of past public health efforts against a dangerous disease.<\/p>\n
Smallpox was a deadly illness that spread quickly and caused high fevers, painful sores, and severe scarring. To stop it, health organizations launched a global vaccination campaign. Their efforts worked, and smallpox was completely wiped out worldwide by 1980.<\/p>\n
