Does a Typhoid Vaccine Last Long?

Contracting typhoid fever in developed countries is rare, but if you are going to be travelling or working in an area where it is more prevalent you will need to ensure you take adequate precautions to protect yourself.

What is Typhoid Fever?
Caused by the salmonella typhi bacteria, typhoid fever is a bacterial infection that is more prevalent in developing countries. The bacteria is ingested through contaminated food and water and can be passed from an infected individual who comes into close contact with others. It can take up to two weeks for symptoms to appear after infection. 

Symptoms can include:

  • A high fever
  • Abdominal pain and extreme swelling of the stomach
  • Headaches
  • Changes in bowel movements like diarrhea or constipation
  • Muscle pain
  • Rashes
  • Sweating

Many who contract typhoid fever will feel better after a few days once they start taking antibiotics, but if typhoid fever is left untreated it can become much more serious. 

As the disease progresses, patients become delirious and may be left in a semi-catatonic state. Once the fever reaches this point, serious and life-threatening complications may arise like intestinal bleeding. This causes the contents from the intestine to leak into the stomach, resulting in severe pain, vomiting, and blood poisoning (sepsis). 

Typhoid Prevention
Often it is not possible when travelling in developing countries to be close to medical facilities, so if you become sick, you might not be able to reach help in time. If you are going to be in an area where typhoid fever exposure is possible, the only way to prevent contracting it is through getting typhoid vaccines. It is a simple 1-dose procedure that can be done up to a week before travel. 

Because no vaccine is 100% effective, you should still practice safety measures like only using bottled water, cooking your own food, sticking to areas with good sanitation, and being close to adequate medical care. 

For continued travel in at-risk regions, it is important to note that typhoid vaccines lose effectiveness over time. For the injectable vaccine, it is recommended to get a booster shot after 2-3 years.
