When you get a tetanus shot, it’s to protect you against a serious bacterial infection known as tetanus. This bacteria can enter the body through cuts or wounds and release toxins that cause muscle stiffness and spasms. The shot is an effective shield against the disease, but, like any medical intervention, it might come with side effects.

Common Side Effects

Typically, after a tetanus vaccination, some people might experience mild side effects. These are signs that your body is building protection, and they usually disappear after a few days.

Pain and Swelling at the Injection Site

It’s quite common to feel a bit of soreness where you got the shot. Also, the area might swell or turn red. This is your immune system reacting to the vaccine, which is a good sign that your body is responding as it should.

If pain or swelling is causing you discomfort, taking an over-the-counter pain medication such as ibuprofen can help provide relief.

Mild Fever

Some individuals might develop a low-grade fever. It’s your body’s natural response to the tetanus vaccination as it’s working to build immunity against tetanus.

Fatigue and Headache

Feeling a bit tired or having a headache are also typical reactions. These symptoms show that your body is using energy to respond to the vaccine, so it’s crucial to rest and stay hydrated.

Nausea

A few people might feel queasy after getting the tetanus shot. If this happens, it’s usually short-lived and not a cause for concern. The Centers for Disease Control and Prevention estimates that one in ten adults receiving the Tdap vaccine will experience this particular side effect.

Less Common Side Effects of Tetanus Vaccine

In some rare cases, you might experience side effects that are less common. These are not typically serious, but they are worth being aware of.

Fever Over 102°F (39°C)

If your fever climbs above 102°F, it’s considered higher than the mild fever that’s more common. While it’s still usually not a reason to worry, you should monitor the fever and consult with a doctor if it persists.

Gastrointestinal Issues

Some individuals might have stomach aches or diarrhea. Although this is rarer, it’s another way your body might react to the tetanus vaccination.

When to See a Doctor

Most tetanus shot side effects are no cause for alarm and will resolve on their own. However, if you notice any of the following, you should seek medical advice:

Severe allergic reactions, such as difficulty breathing or swelling of the face and throat.
High fever that doesn’t reduce with time.
Extreme weakness or dizziness.

Special Considerations

Since you’re considering the vaccine, it’s essential to discuss any allergies with your healthcare provider. Also, if you’ve had a severe reaction to a tetanus shot in the past, make sure to inform your doctor.

In summary, the tetanus shot is a crucial vaccine that can prevent a potentially fatal disease. While side effects can occur, they are generally mild and temporary. Always keep an eye on your reactions post-vaccination and consult with healthcare professionals if you have any concerns.
