Section 1: Smallpox Eradication Smallpox, prevalent until the early 1970s, faced eradication in the Western world. After that, vaccination became unnecessary unless traveling to active virus regions.

Section 2: Vaccination Process The smallpox vaccine, utilizing the Vaccinia virus, induced immune responses. Post-injection, blisters formed and healed, leaving behind distinctive scars.

Section 3: Scar Formation Each needle piercing left a trace, evident in the expanding injection site. Over weeks, a mosquito bite-like lump emerged, evolving into a recurring ulceration process, resulting in irreversible scars.

Section 4: Post-1970s Scenario Post-1970s, smallpox vaccines ceased in the absence of Variola virus exposure. By the 1980s, vaccinations were fully discontinued.

Section 5: Lasting Impact The smallpox vaccination left indelible scars as a testament to the eradication effort’s success. Share this legacy with family and friends!
