What Is Typhoid Fever?

Typhoid fever is caused by the bacteria Salmonella Typhi. Poor sanitation and tainted food or water are the main ways it spreads. Once inside the body, the bacteria multiply and spread through the bloodstream, leading to symptoms that can become severe if left untreated.

Common symptoms include:

High fever
Weakness and fatigue
Headache
Abdominal pain
Loss of appetite
Diarrhea or constipation
Rash in some cases

Without treatment, typhoid fever can lead to serious complications such as intestinal bleeding or perforation. This is why prevention through vaccination is extremely important.

What Is the Typhoid Vaccine?

The typhoid vaccine, also known as the typhoid fever vaccine, is designed to protect individuals from infection caused by Salmonella Typhi. The immune system is stimulated by the vaccine to identify and combat the bacteria before they cause disease.

Typhoid vaccinations come in two primary varieties:

1. Typhoid Injection (Inactivated Vaccine)

The typhoid injection is an inactivated vaccine given as a single shot in the arm. It contains killed bacteria that cannot cause disease but still trigger an immune response.

Key features:

Given as a single intramuscular injection
Recommended for adults and children over two years old
Protection begins about two weeks after vaccination
Booster dose recommended every two years for continued protection

2. Oral Typhoid Vaccine (Live Vaccine)

Another option is an oral vaccine taken as capsules. This vaccine contains a weakened form of the bacteria.

Key features:

Taken as four capsules over several days
Suitable for people aged six years and older
Provides protection for up to five years
Requires proper storage and adherence to dosing schedule

Many people often ask, “Is typhoid a live vaccine?” The answer depends on the type. The oral vaccine is live but weakened, while the injectable version is inactivated.

People working in healthcare, laboratory settings, or areas with poor sanitation benefit greatly from vaccination.

When Should You Get the Typhoid Vaccine?

The timing of vaccination depends on individual risk factors and travel plans.
