The E. coli (ETEC) vaccine is designed to protect against infections caused by Enterotoxigenic Escherichia coli (ETEC), a leading cause of travellers’ diarrhoea and diarrhoeal disease in children.

Escherichia coli (E. coli) is a bacterium typically found in the intestines of humans and animals. While most strains are harmless, certain pathogenic types like ETEC can cause serious gastrointestinal infections by producing toxins that disrupt the normal absorption of fluids in the intestines, leading to diarrhoea. ETEC is a major cause of diarrhoea worldwide, especially in areas with poor sanitation, and poses a significant risk to travellers.

ETEC infections typically cause symptoms such as diarrhoea, abdominal cramps, nausea, and occasionally fever. Fatigue and dehydration may also occur due to fluid loss. Symptoms usually appear within 1-3 days after exposure and typically resolve within a few days. While most cases are mild, severe dehydration may require medical attention.

The E. coli (ETEC) vaccine is typically administered orally, making it easy to take without the need for injections. At ATA Medical, we offer DUKORAL® oral vaccine, which protects against both ETEC and cholera.

For DUKORAL® oral vaccine, the dosage schedule is as follows:

If you're unsure about the appropriate vaccine dosage and schedule, it's best to consult a doctor for guidance.

DUKORAL® oral vaccine provides protection against ETEC travellers' diarrhoea, lasting approximately three months. Additionally, it offers coverage against cholera, with the cholera protection lasting for a longer period.

Common side effects of the E. coli (ETEC) vaccine are mild and may include tiredness, fever, headache, abdominal pain, and diarrhoea. These symptoms typically resolve on their own, but it is advisable to consult a doctor if they persist.

In rare cases, severe allergic reactions might occur, such as swelling of the face or eyes, breathing difficulties, or widespread itchy rashes. Seek immediate medical attention if any of these symptoms are observed​.
