Side Effects of the Typhoid Shot

Typhoid, of typhoid fever, is a serious illness caused by the bacteria Salmonella typhi. It is quite rare in the industrialized world, but it remains common in third-world and developing countries, affecting about 21.5 million people a year, according to the Centers for Disease Control and Prevention. Common symptoms of typhoid fever include a high fever, abdominal pain, headaches and either diarrhea or constipation. The illness can be treated with antibiotics, but people traveling to areas where typhoid fever is prevalent can also receive a vaccine, called Typhim, to prevent them from contracting the illness.

  1. Injection Site

    • Some people receiving the typhoid vaccine will experience some mild redness, swelling, hardening or pain at the injection site. These side effects are normal and are no cause for concern. If the discomfort persists, speak with your doctor.

    Malaise

    • In rare cases, the Typhim vaccine may cause malaise or general body discomfort. This may also include a fever. However, the condition generally lasts only a day or two and is not much cause for concern.

    Gastrointestinal Side Effects

    • Some people who receive the typhoid vaccine before traveling abroad may develop diarrhea or nausea. These side effects are generally mild and do not last very long.

    Other Side Effects

    • Among the other known side effects of Typhim are headaches and muscle pain. As with other side effects, they generally do not persist for more than a day or two.

    Allergic Reactions

    • As with all medications, in rare cases people may develop a severe allergic reaction after receiving the typhoid fever vaccine. Signs of an allergic reaction include hives, wheezing, difficulty breathing or swallowing and swelling of the face, lips, tongue and throat. An allergic reaction can cause a person to go into shock, so immediate medical attention is necessary.
