Vaccination Syringe

The needle that made deadly diseases a memory/Inventions & Discoveries

Edward Jenner performed the first vaccination in 1796, using material from a cowpox lesion to immunize against smallpox. The modern hypodermic syringe was developed by Alexander Wood and Charles Pravaz in the 1850s. A standard vaccination syringe holds about 0.5 to 1 mL, is approximately 8 cm long, and uses a needle with a bore of about 0.5 mm. Vaccination has since prevented an estimated 154 million deaths over the past 50 years.
