Where was the first widely used oral cholera vaccine developed?
Quick Answer
An early widely used oral cholera vaccine was developed in Sweden, with later major deployment in many countries worldwide.
The Full Story
Modern oral cholera vaccines were developed through international research, with important early work in Sweden and later production for global use. Oral vaccines made it much easier to protect people in outbreak settings and refugee camps, where cholera can spread quickly through contaminated water. Cholera causes severe dehydration and can be fatal without rapid treatment. Oral vaccination is now used alongside sanitation and rehydration therapy to control outbreaks.
