### Transcript

> "Good morning, everyone. Today's lecture is about one of the greatest achievements in medical history: vaccination. The story of vaccines is a fascinating journey that has saved millions of lives.

>

> Before vaccines existed, diseases like smallpox killed millions of people every year. In the 18th century, smallpox alone had a mortality rate of about 30 percent — meaning roughly one in three infected people would die.

>

> The breakthrough came in 1796 when an English doctor named Edward Jenner made a remarkable observation. He noticed that milkmaids who had caught cowpox — a mild disease from cows — seemed to be immune to smallpox. Jenner took material from a cowpox sore and inoculated a young boy. Later, when the boy was exposed to smallpox, he did not get sick. This was the world's first vaccine.

>

> The word 'vaccine' actually comes from the Latin word 'vacca,' meaning cow — a reference to Jenner's cowpox experiment.

>

> Over the next two centuries, scientists developed vaccines for many deadly diseases: polio, measles, tetanus, and many others. Perhaps the greatest achievement was the complete eradication of smallpox in 1980. This was the first time humanity had deliberately wiped out a disease.

>

> Today, vaccination programs around the world prevent an estimated 2 to 3 million deaths each year. However, challenges remain — some communities still lack access to basic vaccines, and misinformation about vaccine safety continues to be a problem."
