How It Worked
Administration: The smallpox vaccine was given through multiple small pricks to the upper arm.
Reaction: This method caused a localized reaction, leading to blisters and swelling at the injection site.
Healing Process: Over time, the blister would ooze fluid, scab over, and eventually heal into a circular scar, serving as a permanent reminder of protection against smallpox.
Why It Matters Today
Medical Milestone: Smallpox is the only human disease eradicated through a global vaccination campaign, marking a significant achievement in public health.
Enduring Symbol: The scars left by the vaccine are tangible reminders of medical perseverance and the collective effort to combat deadly diseases.
Modern Parallels: Today’s vaccines continue to protect against various dangerous diseases, underscoring the ongoing relevance of vaccination as a life-saving measure.
