A cholera vaccine is a vaccine that is effective at reducing the risk of contracting cholera.[10] The recommended cholera vaccines are administered orally to elicit local immune response in the gut where the intestinal cells produce antibodies against the cholera microbe. This immune response was poorly achieved with the injectable vaccines that were used until the 1970s. The first effective oral cholera vaccine was Dukoral, developed in Sweden in the 1980s. For the first six months after vaccination it provides about 85% protection, which decreases to approximately 60% during the first two years.[10][11][12] When enough of the population is immunized, it may protect those who have not been immunized thereby increasing the total protective impact to more than 90 % (known as herd immunity).[10]

The World Health Organization (WHO) recommends the use of three oral cholera vaccines – Dukoral, Shanchol, and Euvichol-Plus – in combination with other measures among those at high risk for cholera.[10] Two vaccine doses with a 1–6 week interval are typically recommended.[10] The duration of protection is at least two years in adults and six months in children aged 1–5 years.[10] A live, attenuated single dose oral vaccine is available for those traveling to an area where cholera is common but is not WHO approved for public health use.[13][14][15]

The available types of oral cholera vaccine are generally considered safe for the majority of the population.[10] These vaccines were shown to be safe in pregnancy and in those with poor immune function.[10] The main side effects which could be experienced includes mild abdominal pain or diarrhea may occur.[10]

The first cholera vaccines were developed in the late 19th century.[16] They were the first widely used vaccine that was made in a laboratory but were largely abandoned in the 1970s due to their then documented reactogenicity and poor efficacy.[16]

Oral cholera vaccines were first introduced in the 1990s.[10] It is on the World Health Organization's List of Essential Medicines.[17][18]

These vaccines are licensed for use in more than 60 countries.[10] In countries where the disease is common, the vaccine appears to be cost effective.[10]
