Can you overdose on the tetanus vaccine?
An overdose of this vaccine is unlikely to occur.
What happens if you get tetanus shots too close together — within a few years instead of the recommended 10 years? Answer From Pritish K. Tosh, M.D. It's usually OK to receive an extra booster of the tetanus vaccine.
Deaths have been reported in temporal association with the administration of tetanus toxoid containing vaccines. On rare occasion, anaphylaxis has been reported following administration of products containing tetanus toxoid.
Immunization against tetanus consists first of a series of either 3 or 4 injections, depending on which type of tetanus toxoid you receive. In addition, it is very important that you get a booster injection every 10 years for the rest of your life.
This is especially true in patients at increased risk of pertussis or its complications; the benefit of a single dose of Tdap at an interval of less than 10 years will likely outweigh the risk of adverse reactions to the vaccine. In addition, an interval as short as two years between Td and Tdap is considered safe.
Like any vaccine, the TDaP shot can have some rare but serious side effects such as brachial neuritis. Brachial neuritis is a rare neurological disorder that causes a sudden onset of shoulder pain, as well as muscle weakness.
Is there any danger from receiving extra doses of a vaccine? Most of the time, your risk of serious side effects does not increase if you get extra doses of a vaccine.
Adults need a tetanus shot (tetanus booster) every 10 years. A booster shot is another dose of a vaccine that you get months or years after a previous dose. Providers call it a booster shot because it “boosts” your immune system again and helps your body protect you from illness.
Tdap vaccine protects against tetanus, diphtheria, and whooping cough (pertussis).
- Confusion.
- convulsions (seizures)
- fever over 103 °F (39.4 °C)
- headache (severe or continuing)
- sleepiness (excessive)
- swelling, blistering, or pain at place of injection (severe or continuing)
- swelling of glands in armpit.
- unusual irritability.
What are the complications of tetanus vaccine?
Mild to moderate pain, redness, or swelling can occur following tetanus vaccination. However, if the injection site is bleeding or you experience pain, redness, or swelling that's so severe that you can't perform your usual activities, contact your doctor.
Who Should Not Get the Tetanus Vaccine? You shouldn't get a Tdap vaccine if you have had a severe allergic reaction after a previous Tdap vaccine. You also shouldn't get a Tdap vaccine if you have a history of coma or seizures within a week following a previous Tdap vaccine.

Adults who have never received a tetanus vaccination should get a Tdap shot. In general, the CDC recommend receiving tetanus vaccination every 10 years.
If there is any doubt about whether or not an adult received the primary series, three doses of Td or Tdap (with Tdap given for at least one of the doses) should be administered; the first dose and second dose should be separated by four weeks and the third dose should be given 6 to 12 months later (figure 2 and figure ...
The Advisory Committee on Immunization Practices does not recommend repeated vaccination with Tdap except in pregnant women, who are recommended to receive Tdap during every pregnancy.
After receiving Tdap, people should receive Td or Tdap every 10 years for routine booster immunization against tetanus and diphtheria, according to previously published guidelines. A dose of Tdap should be administered during each pregnancy, preferably early in the 27 week through 36 week gestation time period.
Also, adults should receive a booster dose of either Tdap or Td (a different vaccine that protects against tetanus and diphtheria but not pertussis) every 10 years, or after 5 years in the case of a severe or dirty wound or burn. Tdap may be given at the same time as other vaccines.
Tell the doctor if you experience rare but serious side effects of tetanus booster including tingling of the hands or feet, hearing problems, trouble swallowing, muscle weakness, or seizures.
Reported neurologic complications of vaccination have included headache, postvaccination (“needle-stick”) syncope, febrile seizures, encephalomyelitis, transverse myelitis, meningitis, and polyneuritis.
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.
How many times can you get a Tdap vaccine?
ALL adults who did not get Tdap vaccine as an adolescent should get one dose of this vaccine. Once they have had this dose, a Td or Tdap booster shot should be given every 10 years.
DTaP (DAPTACEL®, Infanrix®, Kinrix®, Pediarix®, Pentacel®, Quadracel®, and Vaxelis™) provides protection against diphtheria, tetanus, and whooping cough. Tdap (Adacel® and Boostrix®) provides protection against tetanus, diphtheria, and whooping cough.
Every adult should get a Tdap vaccine once if they did not receive it as an adolescent to protect against pertussis (whooping cough), and then a Td (tetanus, diphtheria) or Tdap booster shot every 10 years. In addition, women should get the Tdap vaccine each time they are pregnant, preferably at 27 through 36 weeks.
These symptoms usually go away in a few days. Other common reactions to the Tetanus and Diphtheria (Td) vaccine include: Redness and swelling at the injection site. Fever, headache and muscle soreness may also occur.
Tetanus can lead to death (1 to 2 in 10 cases are fatal).
Tetanus immunoglobulin is a medicine containing antibodies that prevent the tetanus toxin working, stopping its effects on the nerves. It provides immediate, but short-term, protection from tetanus.
The tetanus vaccine doesn't provide lifelong immunity. Protection begins to decrease after about 10 years, which is why doctors advise booster shots every decade. A doctor may recommend children and adults get a booster shot earlier if there's a suspicion they may have been exposed to tetanus-causing spores.
Vaccine Education Center
Diphtheria, tetanus and pertussis are prevented by a childhood vaccine, called DTaP, and a vaccine for adolescents and adults, called Tdap. A version for adults is also available without the pertussis component, called Td.
The child should receive the adolescent Tdap at age 11 through 12 years [7]. If the inadvertent administration of DTaP instead of Tdap as part of the catch-up series occurred in a child age ≥10 years, the DTaP counts as the adolescent Tdap dose (as well as the catch-up dose) [7].
As with other inactivated vaccines, there are disadvantages with toxoid vaccines. Even with the adjuvant, these vaccines do not produce a full immune response. Booster shots are needed to maintain the immunity.
Why does tetanus vaccine hurt so much?
Why Do Tetanus Shots Hurt? If you have received a tetanus shot and your arm is sore, you may be experiencing discomfort due to your body's production of antibodies in response to the viruses in the vaccine.
To stay fully immunized, the CDC recommends that adults receive a booster shot every 10 years. Tetanus boosters help to make sure that you have enough antibodies to neutralize the toxin produced by Clostridium tetani should you get an infection.
The preferred injection site in infants and young children is the vastus lateralis muscle of the thigh. The preferred injection site in older children and adults is the deltoid muscle in the upper arm. Use a needle length appropriate for the age and size of the person receiving the vaccine.
Their analysis shows adults will remain protected against tetanus and diphtheria for at least 30 years without the need for further booster shots, after completing the standard five-dose childhood vaccination series.
Adults need a tetanus shot (tetanus booster) every 10 years. A booster shot is another dose of a vaccine that you get months or years after a previous dose. Providers call it a booster shot because it “boosts” your immune system again and helps your body protect you from illness.
A tetanus-containing vaccine booster is recommended for all adults at 50 years of age and at 65 years of age if it is more than 10 years since the last dose. Vaccination is recommended every 10 years for travellers to countries where health services are difficult to access.
The World Health Organization recommends at least 6 doses of tetanus toxoid-containing vaccine for lifelong protection. The first 3 doses should start at the age of 6 weeks and be completed by the age of 6 months with at least 4 weeks between doses.
An allergic reaction could occur after the vaccinated person leaves the clinic. If you see signs of a severe allergic reaction (hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness), call 9-1-1 and get the person to the nearest hospital.
Side Effects
It is very rare you would have a serious allergic reaction from the vaccine, but if you experience a deep, aching pain and loss of muscle in your upper arm that starts 2 days to 4 weeks after you get the shot, contact your healthcare provider right away.
If the wound is clean and you have not had a tetanus booster in the last 10 years, it is recommended that you receive one. If the wound is dirty or tetanus-prone, then your doctor would likely recommend a tetanus booster if you have not had a tetanus booster shot within the last five years.
Is tdap a strong vaccine?
The Tdap vaccine protects against all three diseases. The Tdap vaccine is highly effective. Since the introduction of vaccines, cases of diphtheria and tetanus have dropped by 99% , while cases of pertussis have dropped by 80%.
The vaccines protect: Nearly everyone (97 in 100) against diphtheria for approximately 10 years. Virtually everyone against tetanus for approximately 10 years.
