Global Shortage of Cholera Vaccines in the Spotlight

A lack of global supply has prompted the international body which distributes oral cholera vaccines during outbreaks and emergencies to temporarily suspend the standard two-dose regimen.

The International Coordinating Group (ICG) says the switch to a single-dose approach will help conserve stocks, allowing the oral vaccine to combat the potentially fatal waterborne disease in more countries, amid an "unprecedented" rise in outbreaks, said WHO in a press release.

"To ease the problem in the longer term, urgent action is needed to increase global vaccine production", said WHO. The ICG will continue to monitor the global epidemiological trends, and will review this decision regularly. The supply of cholera vaccines right now, is extremely limited, said WHO, and has to be coordinated by the ICG which manages the global stockpile.

Of the total 36 million doses forecast to be produced in 2022, 24 million have already been shipped for preventive (17%) and reactive (83%) campaigns, and an additional eight million doses were approved by the ICG for the second round for emergency vaccination in four countries, illustrating the dire shortage of the vaccine.

Cameroon, Nigeria, Kenya and other countries have been battling with outbreaks recently.
