Side Effects of the Tetanus Shot
As with any medicine, there is a very remote chance of a vaccine causing a severe allergic reaction, other serious injury, or death.
Possible Side effects from Vaccines
Any vaccine can cause side effects. For the most part these are minor (for example, a sore arm or low-grade fever) and go away within a few days. Listed below are vaccines licensed in the United States and side effects that have been associated with each of them. This information is copied directly from CDC’s Vaccine Information Statements (VISs), which in turn are derived from the Advisory Committee on Immunization Practices (ACIP) recommendations for each vaccine.
Remember, vaccines are continually monitored for safety, and like any medication, vaccines can cause side effects. However, a decision not to immunize a child also involves risk and could put the child and others who come into contact with him or her at risk of contracting a potentially deadly disease.
Regularly Recommended Vaccines
DTaP vaccine side effects (Diphtheria, Tetanus, and acellular Pertussis)
What are the risks from DTaP vaccine?
- Soreness or swelling where the shot was given, fever, fussiness, feeling tired, loss of appetite, and vomiting sometimes happen after DTaP vaccination.

About the tetanus shot
Tetanus is a serious disease that’s caused by the bacterium Clostridium tetani (C. tetani).
C. tetani lives in soil and manure. It usually enters your body through an open wound. A toxin that’s produced by the bacterium causes the disease, also referred to as lockjaw.
Although rare in the United States, 1 in 10 people who contract it die, according to the Centers for Disease Control and Prevention (CDC) .
The tetanus vaccine helps protect against tetanus. The vaccine that you get for tetanus can also contain components to prevent contracting certain other serious bacterial diseases, such as diphtheria and pertussis (whooping cough).
The different tetanus vaccine formulations are as follows:
- DTaP. This vaccine prevents tetanus, diphtheria, and pertussis. It’s used for children younger than 7 years old.
- Tdap. This vaccine prevents tetanus, diphtheria, and pertussis. It’s used for older children and adults.
- DT and Td. These prevent tetanus and diphtheria. DT is given to younger children, while Td is typically given to older children and adults.
There are some mild side effects to any of the tetanus vaccines. These side effects are common to all types of tetanus shot. Most of these side effects are signs that your body is responding to build immunity against the disease.
Pain, redness, or swelling at the injection site
Pain at the injection site is one of the most common side effects from receiving the tetanus vaccine. According to the CDC, it occurs in 2 in 3 adults that receive the Tdap vaccine. This should subside in a few days.
If pain or swelling is causing you discomfort, you can take an over-the-counter (OTC) pain medication such as ibuprofen (Advil) to help.
Fever
People receiving the tetanus vaccine can experience a mild fever of up to 100.4ºF (38ºC) following vaccination.
If you experience a mild fever following tetanus vaccination, OTC medications such as acetaminophen (Tylenol) or ibuprofen can help.
Headache or other body aches
You may experience a headache or various aches and pains throughout your body after your tetanus vaccination. These side effects should subside shortly.
You can take a pain reliever such as ibuprofen or acetaminophen for aches.
Tiredness
You may feel tired or drowsy following your tetanus vaccination. This is a completely common side effect. Like many of the previously listed side effects, it’s a sign that your body and immune system are working hard to build up immunity.
Nausea, vomiting, or diarrhea
Experiencing nausea, vomiting, or diarrhea is considered a mild side effect of the Tdap vaccine. The CDC estimates 1 in 10 adults receiving the Tdap vaccine will experience this side effect.
If you experience this, be sure to rest, drink plenty of fluids, and avoid foods that could further upset your stomach.

What are the side effects of the tetanus shot?
Tetanus is a rare but potentially dangerous disease that causes stiffening and tightening of the muscles. The tetanus vaccine protects people who may come into contact with the bacteria that cause the disease. As with any vaccine, it can lead to the possibility of some side effects.
Tetanus occurs as a result of a bacterial infection. According to the Centers for Disease Control and Prevention (CDC), tetanus kills one out of every ten people who contract the disease.
The bacteria that cause tetanus may be most common in substances such as dust, soil, or manure. They often enter the body through injuries that include scratches or cuts.
Vaccines are a type of medication and, just as with other medicines, there is always the possibility of side effects.
With that said, most people who get a tetanus shot will not experience any symptoms.
The most common side effects of a tetanus shot include:
- redness and swelling at injection site
- body aches
- fever
- a headache
- tiredness or feeling weak
Serious side effects are not common but may still occur in certain people.
Below, we list some of the more frequent side effects people may experience after a tetanus shot:
Pain at the injection site
The most common side effect is pain at the site of the injection. According to the CDC, this occurs in about eight in every 10 people. This pain is a person’s body having a mild reaction to the injection, and it should fade within a few days.
Redness or swelling
Some people may experience a slightly more intense reaction from the injection, causing their skin around the injection site to become red and swollen.
The CDC say that one in four people will experience redness or swelling. Over-the-counter (OTC) medicines for pain, including ibuprofen (Advil) or acetaminophen (Tylenol), may help.
Mild fever
Although it is rarer than the other common side effects, some people may develop a low-grade fever in response to the tetanus vaccine. The fever should subside without intervention, but, again, OTC medication may help ease symptoms.
Headache
Some people experience a headache after a tetanus injection. This side effect is usually nothing serious, and OTC drugs may help ease symptoms.
Tiredness or fatigue
People receiving a tetanus shot may feel tired or have general fatigue afterward. This is typically a response to the vaccination as the body pools its energy to build up its immunity.
The CDC estimate that one in four people will experience tiredness. It may be best for a person to let these symptoms run their course, and to get as much rest as possible.
Sore joints or chills
The Tdap vaccine, which protects against tetanus, diphtheria, and whooping cough, is sometimes given as an alternative to the tetanus and diphtheria vaccine and may also cause a person to experience sore joints or chills over their body.
The CDC estimates this may occur in about one in every 10 cases, but the symptoms usually do not interfere with everyday life. OTC medications may help in these cases as well.
Some side effects are classified as moderate, meaning they may interfere with someone’s daily activities, but they do not need medical intervention.
Fever
It is possible for people to experience a fever as a reaction to the tetanus vaccine. The CDC consider this a relatively rare occurrence, however.
Though the symptom may make someone feel unwell, they do not generally require medical attention. Drinking plenty of fluids and getting rest should help to speed up recovery.
Nevertheless, anyone with a fever that lasts more than a couple of days or who has signs of dehydration should seek medical attention.
Nausea, vomiting, or diarrhea
Share on Pinterest Some forms of the tetanus vaccine can cause nausea, vomiting, or diarrhea.
Some forms of the tetanus vaccine, such as the Tdap, may cause gastrointestinal symptoms, including nausea, vomiting, or diarrhea.
The CDC estimate that one to three people in 100 will have moderate gastrointestinal symptoms after the Tdap vaccine.
The best course of action is to drink plenty of fluids, rest, and eat plain food to avoid aggravating the gastrointestinal system any further.
The symptoms will usually subside with time.
Rash or swollen glands
Occasionally, a person may develop a rash or other skin reaction from the tetanus shot. The glands in their body may swell up as a response to the injection. This side effect is not common and tends to go away on its own.
Swelling of the arm
Some people may experience more extensive swelling in the arm where they received the injection.
The CDC estimate that one in every 500 people may experience swelling of their entire arm after an injection of the Tdap vaccine. However, it describes this as a moderate effect, which does not typically need medical intervention.
Below are some more severe side effects that can result from the tetanus shot and may need medical attention.
Swelling and severe pain, redness, or bleeding
In rare cases, swelling, redness, and severe pain may occur after the injection. The skin may break and bleed as a response to the vaccine. This occurs around the injection site and requires medical attention.
Severe allergic reaction
There is also a rare possibility of a person having a severe allergic reaction to the vaccine. The CDC estimate that this form of reaction happens in less than one in every 1 million cases.
Symptoms of an allergic reaction include:
- difficulty breathing or swallowing
- itchy throat, feet, or hands
- hives
- swelling in the face, eyes, or airways
- sudden severe fatigue
- rapid heartbeat
The reaction would start to happen between a few minutes to a few hours after receiving the injection, and it requires immediate medical attention.
The tetanus vaccine does not cause autism.
While people express concerns about the potential for serious side effects from vaccines, this worry may come partly from misinformation. As the United States Department of Health and Human Services state, research shows vaccines do not lead to autism.
Medical researchers monitor vaccines constantly, and any evidence that linked vaccinations to severe disabilities or other health problems would lead to medical authorities taking swift safety measures.
There are several different types of tetanus shots available. Producers often package the tetanus shot with other similar vaccines, so that it works to prevent more than one type of disease. These vaccines may be as follows:
Tdap: The Tdap vaccine prevents tetanus, while also working to prevent diphtheria and pertussis, or whooping cough.
DTaP: The DTaP vaccine is the form doctors often use for very young children. It prevents tetanus, diphtheria, and pertussis.
Td or DT: The Td and DT shots prevent tetanus and diphtheria, and doctors use these as tetanus booster shots. A period of 10 years is the longest a person should go without a tetanus booster.
Share on Pinterest Anyone who has had severe pain after a previous tetanus vaccine should discuss their options with a doctor.
Some people should avoid the tetanus shot. Anyone who has ever had a severe allergic reaction to tetanus vaccines in the past should avoid having the tetanus shot again.
Most people get a tetanus shot as a child, and so it is helpful if people are aware of any reactions they had when they were young.
Anyone with experiences of serious complications from a childhood dose of the tetanus shot, such as seizures or a coma, should avoid the tetanus shot in the future.
People with certain conditions may also want to be wary when looking to get a tetanus shot and should talk to their doctor to discuss their options.
People should be cautious if they have ever had:
- severe pain or swelling from a tetanus vaccine
- seizures
- nervous system conditions
- Guillain Barre syndrome where the immune system attacks nerve cells
Some tetanus vaccines may pose a risk to the health of people with any of these concerns. Doctors can advise them on how they should take care to avoid the diseases a vaccine would protect against.
People should always discuss any health concerns or conditions they have with a doctor before having any vaccine.
Side effects of a tetanus shot are uncommon, mild, and usually go away on their own in a few days. Most people think the chances of having side effects are much smaller than the risks of conditions such as tetanus.
Rarely, people may have a severe reaction to the vaccines and should avoid them, but these reactions are not common. The tetanus shot is a safe and effective way to prevent tetanus and other dangerous diseases occurring in most cases.
Anyone with concerns about the vaccine or the possible side effects should talk to their doctor.
