How was tetanus treated before vaccine?
The resulting antitoxins created a serum that could be obtained from the horse containing the antitoxin and be used for treatment in humans. This was the primary way to treat tetanus until the development of the tetanus toxoid in 1924.
When was the tetanus shot invented?
The next routinely recommended vaccines were developed early in the 20th century. These included vaccines that protect against pertussis (1914), diphtheria (1926), and tetanus (1938). These three vaccines were combined in 1948 and given as the DTP vaccine.
When did the FDA approve the tetanus vaccine?
On December 17, 1991, the Food and Drug Administration (FDA) approved a diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP) prepared and distributed by Lederle Laboratories (Pearl River, New York) as ACEL-IMUNE\T * (3).
How did they treat tetanus?
Medications. Antitoxin therapy is used to target toxins that have not yet attacked nerve tissues. This treatment, called passive immunization, is a human antibody to the toxin. Sedatives that slow the function of the nervous system can help control muscle spasms.
Is Johnson and Johnson vaccine FDA approved?
The Food and Drug Administration yesterday revised its emergency use authorization for the Johnson & Johnson COVID-19 vaccine to limit its use to individuals 18 and older for whom the other authorized or approved vaccines are not accessible or clinically appropriate, or who choose to receive it because they would ...
Who makes the Tdap vaccine?
Tetanus, Diphtheria, and Pertussis (Tdap) Vaccines Each 0.5-mL dose of Adacel® (Sanofi Pasteur) contains 5 Lf tetanus toxoid, 2 Lf diphtheria toxoid, and acellular pertussis antigens (2.5 µg detoxified PT, 5 µg FHA, 3 µg pertactin, 5 µg FIM).
Overview
Tetanus, also known as lockjaw, is a bacterial infection caused by Clostridium tetani, and is characterized by muscle spasms. In the most common type, the spasms begin in the jaw and then progress to the rest of the body. Each spasm usually lasts a few minutes. Spasms occur frequently for three to four weeks. Some spasms may be severe enough to fracture bones. Other symptoms of tetanus may include fever, sweating, headache, trouble swallowing, high blood pressure, and a fast heart rate. Onset of symptoms is typically three to twenty-one days fo…
Signs and symptoms
Tetanus often begins with mild spasms in the jaw muscles—also known as lockjaw. Similar spasms can also be a feature of trismus. The spasms can also affect the facial muscles resulting in an appearance called risus sardonicus. Chest, neck, back, abdominal muscles and buttocks may be affected. Back muscle spasms often cause arching, called opisthotonus. Sometimes the spasms affect muscles that help with breathing, which can lead to breathing problems.
Cause
Tetanus is caused by the tetanus bacterium Clostridium tetani. Tetanus is an international health problem, as C. tetani endospores are ubiquitous. Endospores can be introduced into the body through a puncture wound (penetrating trauma). Due to C. tetani being an anaerobic bacterium, it and its endospores thrive in environments that lack oxygen, such as a puncture wound. With the changes in oxygen levels, the drumstick-shaped endospore can result in quick spread.
Pathophysiology
Tetanus neurotoxin (TeNT) binds to the presynaptic membrane of the neuromuscular junction, is internalized and is transported back through the axon until it reaches the central nervous system. Here, it selectively binds to and is transported into inhibitory neurons via endocytosis. It then leaves the vesicle for the neuron cytosol where it cleaves vesicle associated membrane protein (VAMP) synaptobrevin, which is necessary for membrane fusion of small synaptic vesicles (SSV's). SSV's carry neurotransmitter to the membrane for release, so inhibition of this pr…
Diagnosis
There are currently no blood tests for diagnosing tetanus. The diagnosis is based on the presentation of tetanus symptoms and does not depend upon isolation of the bacterium, which is recovered from the wound in only 30% of cases and can be isolated from people without tetanus. Laboratory identification of C. tetani can be demonstrated only by production of tetanospasmin in mice. Having recently experienced head trauma may indicate cephalic tetanus if no other diagnosis has been made.
Prevention
Unlike many infectious diseases, recovery from naturally acquired tetanus does not usually result in immunity to tetanus. This is due to the extreme potency of the tetanospasmin toxin. Tetanospasmin will likely be lethal before it will provoke an immune response.
Tetanus can be prevented by vaccination with tetanus toxoid. The CDC recommends that adults receive a booster vaccine every ten years, and standard care practice in many places is to give the booster to any person with a pu…
Treatment
Mild cases of tetanus can be treated with:
• Tetanus immunoglobulin (TIG), also called tetanus antibodies or tetanus antitoxin. It can be given as intravenous therapy or by intramuscular injection.
• Antibiotic therapy to reduce toxin production. Metronidazole intravenous (IV) is a preferred treatment.
Epidemiology
In 2013 it caused about 59,000 deaths – down from 356,000 in 1990. Tetanus – in particular, the neonatal form – remains a significant public health problem in non-industrialized countries with 59,000 newborns worldwide dying in 2008 as a result of neonatal tetanus. In the United States, from 2000 through 2007 an average of 31 cases were reported per year. Nearly all of the cases in the United States occur in unimmunized individuals or individuals who have allowed their inoculations to lapse.

Epidemiology
- The global neonatal tetanus elimination goal was launched at the World Health Assembly in 1989 to reduce neonatal tetanus as a public health problem (defined as less than one case of neonatal tetanus per 1000 live births in every district) in all countries. The Maternal and Neonatal Tetanus Elimination (MNTE) Initiative was launched by UNICEF, WHO ...
Secular Trends in The United States
Tetanus Toxoid-Containing Vaccines
- C. tetaniusually enters the body through a wound. In the presence of anaerobic conditions, the spores germinate. Toxins are produced and disseminated via blood and lymphatics. Tetanospasmin, also referred to as tetanus toxin, acts at several sites within the central nervous system, including peripheral motor end plates, the spinal cord, and the brain, and in the sympathetic nervous system. The typical clinical manifestations of tetanus are ca…
Vaccination Schedule and Use
- The incubation period is usually about 8 days, with a usual range of 1 to 21 days. In general, the incubation period is longer the further the injury site is from the central nervous system. Shorter incubation periods are also associated with severe disease and a higher chance of death. On the basis of clinical findings, three different forms of tetanus have been described. The most common type (more than 80% of reported cases) is generalize…
Contraindications and Precautions to Vaccination
- Occurrence
Tetanus occurs worldwide but is most frequently encountered in densely populated regions in hot, damp climates with soil rich in organic matter. - Reservoir
Organisms are found primarily in the soil and intestinal tracts of animals and humans.
Vaccine Safety
- A marked decrease in mortality from tetanus occurred from the early 1900s to the late 1940s. In the late 1940s, tetanus toxoid-containing vaccines were introduced into routine childhood vaccination and tetanus became a nationally notifiable disease. At that time, between 500–600 cases (approximately 0.4 cases per 100,000 population) were reported per year. After the 1940s, reported tetanus incidence rates declined steadily. Since th…
Vaccine Storage and Handling
- Tetanus toxoid is combined with diphtheria toxoid as diphtheria and tetanus toxoid (DT) vaccine or tetanus and diphtheria toxoid (Td [Tenivac and Tdvax]) vaccine. Tetanus toxoid is also combined with both diphtheria toxoid and acellular pertussis vaccine as DTaP (Infanrix and Daptacel) or Tdap (Boostrix and Adacel) vaccines. Td contains reduced amounts of diphtheria toxoid compared with DT. DTaP and Tdap contain the same pertussis c…
