What Is the Typhoid Vaccine and How Does It Prevent Infection?
Typhoid fever is a serious infection caused by the bacterium Salmonella typhi. It can lead to high fever, weakness, stomach pain, and sometimes even serious complications if left untreated. Fortunately, there is a simple and effective way to protect yourself from this disease: the typhoid vaccine.
In this article, we’ll explore what the typhoid vaccine is, how it works, its effectiveness, and why it’s important to get vaccinated, especially if you’re travelling to areas where typhoid is common.
What is the Typhoid Vaccine?
The typhoid vaccine is a shot or oral treatment that helps protect against typhoid fever. There are two main types of vaccines available: the injectable vaccine and the oral vaccine. Both work to stimulate the body’s immune system to fight off the Salmonella typhi bacteria before it can cause infection.
The injectable vaccine, known as the Vi polysaccharide vaccine, is given as a single dose, typically under the skin or into the muscle. The oral version, the Ty21a vaccine, comes in capsule form and is taken over a few days. Both vaccines are safe and effective in preventing typhoid fever.
How Does the Typhoid Vaccine Work?
The typhoid vaccine works by introducing a small amount of the Salmonella typhi bacteria or its components into the body. This doesn’t cause illness but helps the immune system recognise and fight off the bacteria if you are exposed to it in the future.
For example, the injectable vaccine contains a part of the bacteria’s outer layer, which trains the body to identify and attack the bacteria if it enters the system. The oral vaccine works similarly by using a weakened form of the bacteria, allowing the body to build immunity over time.
Once vaccinated, the body becomes “immune” to the infection. If you come into contact with the Salmonella typhi bacteria, your immune system will be ready to fight it off, reducing the risk of getting sick.
Typhoid Vaccine Effectiveness
The effectiveness of the typhoid vaccine varies, but overall, it provides strong protection. The injectable vaccine offers about 70-80% protection against typhoid fever, while the oral vaccine provides slightly less, around 50-70% protection. Although these figures may seem lower than some other vaccines, the typhoid vaccine is still one of the best preventive measures available.
It’s important to note that no vaccine is 100% effective. However, the typhoid vaccine can still significantly reduce the risk of infection, especially in combination with other preventive measures such as good hygiene practices and clean drinking water.
For those who are travelling to areas with poor sanitation, the vaccine is highly recommended, as it offers an additional layer of protection against typhoid fever.
How Long Does the Typhoid Vaccine Last?
The protection offered by the typhoid vaccine isn’t permanent, so it’s important to keep track of when you need a booster shot.
- For the injectable vaccine, immunity lasts for around 2-3 years, after which a booster dose is recommended.
- The oral vaccine also requires a booster after 5 years to maintain immunity.
Why Should You Get Vaccinated?
Typhoid fever is a preventable disease, but it can have serious consequences if not treated early. Getting vaccinated helps protect you and the people around you from the disease. It is particularly important if you are travelling to countries where sanitation and hygiene conditions are poor.
