Varicella, popularly known as chickenpox, is an infectious disease caused by the Varicella zoster virus(VZV). Before the invention of the Michiaki Takahashi chickenpox vaccine, millions of children across the world were affected by the disease, as it was easily transmittable. However, the adults were more affected than children.
Discovery of the Varicella Vaccine
Japanese virologist Dr. Michiaki Takahashi developed the world’s first chickenpox vaccine in 1974. He was born on February 17, 1928, in Osaka, Japan. Takahashi got his medical degree from Osaka University and joined the Research Institute for Microbial Disease in the same Takahashi University. He went to the U.S. to do research at Baylor college in 1963. Takahashi’s son was affected by a severe chickenpox virus which paved the way for the discovery of the varicella vaccine. In 1964, Takashaki experimented with the weakened chickenpox viruses, and after five years, the vaccine was ready to test humans. After many successful tests on patients, the vaccine was launched in 1974. WHO approved the varicella vaccine in 1986. Takahashi named the vaccine “Oka” after his family name. Takahashi’s vaccine became a huge hit and helped to prevent infectious diseases.
