Oral Cholera Vaccine Introduced

While cholera is preventable and treatable, global cases and deaths have risen steadily since 2021. From early 2023 to March this year, 824,479 cases and 5,900 deaths were reported in 31 countries.

The United Nations humanitarian agency has heightened its response to tackle the cholera outbreak in Somalia, with the death toll reaching 120 since January.

While global demand for OCVs exceeds 100 million doses annually, there is currently only one manufacturer supplying OCVs worldwide, resulting in a yearly deficit of about 40 million doses.

The new vaccine will bridge the gap and also contribute substantially to the Global Task Force on Cholera Control (GTFCC)'s goal of reducing cholera-related deaths by 90 percent by 2030, alongside improvements in water and sanitation infrastructure.
