What Is Typhoid Vaccine?

Typhoid fever is a serious disease that has the potential to be fatal. A germ known as Salmonella typhi is responsible for the disease’s development, and it is most commonly transmitted through contaminated food or drink. It is also possible that typhoid is spread by close person-to-person contact with sick individuals (such as occurs with persons living in the same household). Infected individuals may not appear to be unwell, yet they are still capable of spreading the disease to others.

Typhoid fever is extremely rare in the United States and other parts of the world where water and sewage (waste) systems are well-developed. However, it is a problem in parts of the world where there is no such system in operation.

Why Is The Typhoid Vaccine Important?

Typhoid can lead to serious complications, like a high fever that can last for weeks or months. As many as three out of every ten persons who contract typhoid and do not receive treatment will die.

While travelling, it is possible for Americans to contract typhoid. In the event that you are travelling to an area where typhoid fever is prevalent, being vaccinated is one approach to protect yourself.

Who Needs To Get The Typhoid Vaccine?

It is suggested that persons who are at high risk of contracting typhoid be immunised against the disease. For example, if you have any of the following symptoms, you may require the typhoid vaccine:

  • Are in close contact with someone who has typhoid
  • Work in a lab studying typhoid
  • Are travelling to a country where typhoid is common

Typhoid Vaccine: A single dose should be administered at least 2 weeks before travel, with an additional booster dose administered every 2 years after that. People who receive the oral typhoid vaccine will require four doses every other day for a week, with the final dose administered at least one week before travel, as well as a booster shot every five years.

Consult your doctor for advice on how to keep your family safe from typhoid fever. You should check with your travel destination to see if the typhoid vaccine is recommended.

Typhoid Vaccine

There are two vaccines available to protect against typhoid fever. The difference between the two vaccines is that one is inactivated (killed) and the other is live and attenuated (weakened). Your health-care provider can assist you in determining which type of typhoid vaccine is the most appropriate for your needs.

It is necessary to administer the inactivated typhoid vaccine by injection (shot). It can be given to anyone who is 2 years old or older. It is recommended to take one dose at least two weeks before travelling. It is recommended that people who remain at risk receive repeated doses every two years.

Oral administration of live typhoid vaccine is recommended (by mouth). It may be administered to individuals 6 years of age and older. Every other day, one capsule is taken, for a total of four capsules per day. The final dose should be taken at least one week before departure. Take one capsule with cold or lukewarm water about an hour before meals, swallowing the capsule whole (do not chew). For people who continue to be at risk, a booster vaccine is required every 5 years. It is critical to remember that live typhoid vaccine capsules must be kept refrigerated (not frozen).

In the United States, routine typhoid vaccination is not recommended; however, typhoid vaccine is recommended for the following situations:

Travellers to regions of the world where typhoid fever is prevalent.

Individuals who have had close contact with a typhoid carrier.

Workers in a laboratory who come into contact with the Salmonella typhi bacteria. In some cases, typhoid vaccines can be administered at the same time as other vaccines.

Advice For Travellers

Irrespective of whether you have received a typhoid vaccine or not, it is critical to take basic precautions when travelling to countries where typhoid fever is present.

For Example:

  • Make sure to only drink bottled water from a bottle that has been properly sealed or water that has recently been boiled. 
  • Avoid eating ice cream and making sure there is no ice in your drinks.
  • Uncooked fruit and vegetables should be avoided unless they have been thoroughly washed in safe water and peeled by you.
  • Stay away from shellfish, seafood, and salads.
