3 min read 16-03-2025

Choosing to get a typhoid vaccine is a crucial step in protecting yourself from this potentially life-threatening bacterial infection. However, like all vaccines, there's a possibility of experiencing side effects. Understanding these potential side effects beforehand can help manage expectations and alleviate any anxieties.

Understanding Typhoid and its Prevention

Typhoid fever, caused by the bacteria Salmonella Typhi, is a serious illness spread through contaminated food and water. Symptoms can range from mild to severe, including fever, headache, stomach pain, and diarrhea. In severe cases, typhoid can be fatal. Vaccination is a highly effective way to prevent this disease, particularly for travelers visiting regions with a high risk of typhoid.

There are two main types of typhoid vaccines: a live, attenuated oral vaccine (Vivotif) and a parenteral (injected) vaccine (Typhim Vi). Each has its own set of potential side effects.

Common Side Effects of Typhoid Vaccines

Oral Typhoid Vaccine (Vivotif) Side Effects:

The oral typhoid vaccine is generally well-tolerated, but some people experience mild side effects. These typically include:

Mild stomach upset: This can manifest as nausea, mild abdominal cramps, or diarrhea. These are usually temporary and subside within a few days.
Headache:
Fatigue:
Muscle aches:

These side effects are usually mild and resolve on their own. However, if symptoms persist or worsen, it’s essential to consult a doctor.

Injectable Typhoid Vaccine (Typhim Vi) Side Effects:

The injectable typhoid vaccine also has a generally good safety profile. Common side effects are usually mild and short-lived. These can include:

Pain, redness, or swelling at the injection site:
Headache:
Fatigue:
Muscle aches:
Low-grade fever:

Similar to the oral vaccine, these effects usually disappear within a few days. Seek medical advice if symptoms are severe or persistent.

Rare but Serious Side Effects

While rare, more serious side effects are possible with both vaccines. These are less common but require immediate medical attention:

Severe allergic reactions (anaphylaxis): Symptoms include difficulty breathing, swelling of the face or throat, and a rapid heartbeat. This is a medical emergency requiring immediate attention.
Guillain-Barré syndrome (GBS): This is a rare neurological disorder characterized by muscle weakness and paralysis. While a link to typhoid vaccines is extremely rare, it's important to be aware of the possibility.

Who Shouldn't Get a Typhoid Vaccine?

Certain individuals should avoid getting a typhoid vaccine. Consult your doctor before getting vaccinated if you:

Have a weakened immune system.
Are allergic to any component of the vaccine.
Have a history of GBS or other neurological disorders.
Are pregnant or breastfeeding (consult your doctor for specific advice).

Managing Side Effects

Most typhoid vaccine side effects are mild and can be managed with over-the-counter pain relievers like ibuprofen or acetaminophen. Resting and staying hydrated can also help alleviate symptoms. If you experience any concerning side effects, contact your doctor immediately.

Conclusion

While typhoid vaccines offer significant protection against typhoid fever, it's crucial to be aware of the potential side effects. Understanding these possibilities and knowing when to seek medical attention can help ensure a safe and effective vaccination experience. Remember to discuss any concerns with your doctor before getting vaccinated.
