Reviewing the Data

The cholera vaccine’s effectiveness has long been debated due to variant study findings. To resolve the discrepancies, a team led by JHSPH researchers conducted an extensive literature review.

Their study, published in The Lancet, found that the standard 2-dose vaccine had 76% effectiveness in adults for up to 3 years and that 1 dose gave adequate short-term protection. The regimen, however, is significantly less protective for children under 5.

The implications for vaccine policy could include limiting vaccines to 1 dose for adults to control outbreaks and developing new regimens for children.
