Find a typhoid vaccine near me

Typhoid fever is a serious, potentially life-threatening illness caused by bacteria found in contaminated food or water. Although rare in the U.S., it’s common in parts of Asia, Africa, and Latin America. Fortunately, typhoid vaccines offer protection for travelers and others at risk.

What is typhoid fever?

Typhoid fever is a serious bacterial infection caused by the bacterium Salmonella enterica serotype Typhi (S. Typhi). It is primarily transmitted through contaminated food and water, often in areas with poor sanitation. Once ingested, the bacteria invade the intestinal walls and can enter the bloodstream, leading to systemic infection. Symptoms typically include prolonged fever, weakness, abdominal pain, headache, and loss of appetite. If left untreated, typhoid fever can result in severe complications and can be life-threatening.

Vaccination is an effective way to prevent typhoid fever, according to the CDC — especially for individuals traveling to regions where the disease is prevalent. Treatment usually involves antibiotics, although antibiotic resistance is becoming an increasing concern. Prompt medical attention is important for a full recovery, and maintaining good hygiene practices, such as proper handwashing and safe food preparation, can significantly reduce the risk of infection.

Who should get a typhoid fever vaccine?

According to the CDC, typhoid vaccination is recommended for people at higher risk of exposure to Salmonella Typhi, the bacteria that causes typhoid fever. This includes:

• International travelers going to countries where typhoid fever is common, such as parts of Asia (especially India, Pakistan, Bangladesh), Africa, the Caribbean, Central and South America, and the Middle East.
• People in close contact with someone who is actively infected or a chronic carrier of the bacteria.
• Laboratory workers who handle Salmonella Typhi bacteria.

It’s best to get vaccinated at least 2–3 weeks before travel. Talk to a healthcare provider to determine if you need the oral or injectable vaccine.

How effective is the vaccine?

Typhoid fever vaccines are effective, but not foolproof. The injectable typhoid vaccine is about 50–80% effective, while the oral vaccine provides around 60–80% protection. Both vaccines reduce the severity of illness if you do get infected.

Because protection wanes over time, booster doses are recommended every 2–5 years for ongoing risk. While the vaccine lowers your chances of getting sick, it’s important to also practice safe food and water habits, especially when traveling. Avoid raw produce, street food, and unfiltered water to maximize your protection.
