Tenivac is a Td vaccine that immunizes adults and children over the age of seven against diphtheria and tetanus. It is a booster shot that is recommended every 10 years and contains a full-strength dose of tetanus (T) toxoids and a lower-strength dose of diphtheria (d) toxoids. Other ingredients in Tenivac include ≤5.0 µg of residual formaldehyde, aluminum phosphate (0.33 mg aluminum) as the adjuvant, modified Mueller-Miller casamino acid medium without beef heart infusion, and ammonium sulfate. This article will explore whether Tenivac contains less formaldehyde than other DT vaccines.

What You'll Learn
Tenivac® contains ≤5.0 µg of residual formaldehyde
Tenivac is a Td vaccine that immunizes adults and people over the age of 7 against diphtheria and tetanus. It is a booster shot that is recommended every 10 years and is injected into the upper arm muscle. It contains ≤5.0 µg of residual formaldehyde per 0.5-mL dose.
Formaldehyde is a naturally occurring chemical found in the human body and in almost all living things. It is also present in the environment and is produced by forest fires, volcanic eruptions, and cigarette smoke. Formaldehyde is used in various industries, including the production of building materials, household products, and vaccines.
In vaccines, formaldehyde is used as a preservative and to inactivate toxins and viruses. It helps to ensure the safety and effectiveness of the vaccine by preventing the growth of bacteria and other microorganisms. The amount of formaldehyde in vaccines is carefully controlled and monitored to ensure that it is safe for human use.
The amount of residual formaldehyde in Tenivac is within the acceptable range for vaccine production and is similar to the amount found in other DTaP and Tdap vaccines. For example, each 0.5-mL dose of DAPTACEL® (Sanofi Pasteur) contains ≤5 µg residual formaldehyde, while Infanrix® (GlaxoSmithKline) contains ≤100 µg of residual formaldehyde per 0.5-mL dose.
While formaldehyde is generally considered safe at low levels, some people may have sensitivity or allergies to it. It is important for individuals to discuss their medical history and any potential allergies with their healthcare provider before receiving any vaccine, including Tenivac.

Other DT vaccines contain ≤100 µg of residual formaldehyde
Tenivac is a Td vaccine that immunizes adults against tetanus and diphtheria. It is a booster shot that is recommended every 10 years. It contains ≤5.0 µg of residual formaldehyde per 0.5-mL dose.
Other DT vaccines on the market include Infanrix®, Kinrix®, Pediarix®, Pentacel®, Quadracel®, and Vaxelis™. Each 0.5-mL dose of Infanrix® contains ≤100 µg of residual formaldehyde. Similarly, each 0.5-mL dose of Kinrix® contains ≤100 µg of residual formaldehyde. Pediarix®, another DT vaccine, contains ≤100 µg of residual formaldehyde per 0.5-mL dose. Pentacel® contains ≤5 µg of residual formaldehyde per 0.5-mL dose.
Therefore, compared to other DT vaccines, Tenivac does contain less formaldehyde.

Tenivac® is a Td vaccine that immunizes against tetanus and diphtheria
In addition to the active ingredients, Tenivac also contains other components. These include aluminum phosphate (0.33 mg of aluminum) as an adjuvant, ≤5.0 µg of residual formaldehyde, modified Mueller-Miller casamino acid medium without beef heart infusion, and ammonium sulfate. The presence of formaldehyde in vaccines has been a topic of discussion, and Tenivac does contain a small amount. However, it is important to note that formaldehyde is also naturally produced by the human body and is present in many foods we consume.
Tenivac is considered safe for most individuals, but there are some contraindications and potential side effects to consider. It should not be given to anyone who has had a severe allergic reaction to a previous dose of a vaccine against diphtheria or tetanus, or any other ingredient in Tenivac, including latex found in the tip caps of the pre-filled syringes. Latex sensitivity may trigger allergic reactions in individuals allergic to latex. Other potential side effects include pain, redness, or swelling at the injection site, headache, tiredness, mild fever, muscle weakness, joint pain, and, in rare cases, brachial neuritis.
Tenivac is a Td vaccine, which means it does not contain the pertussis component found in Tdap vaccines. Tdap vaccines, such as the one given to teenagers between 11 and 18 years old, protect against tetanus, diphtheria, and pertussis (whooping cough). Tenivac is recommended as a booster shot every 10 years for adults who have previously received a Tdap vaccine.

Tdap vaccines prevent tetanus, diphtheria, and pertussis
Tdap vaccines, such as Daptacel®, Infanrix®, Kinrix®, Pediarix®, Pentacel®, Quadracel®, and Vaxelis™, prevent tetanus, diphtheria, and pertussis. Tetanus, diphtheria, and pertussis can all cause serious, life-threatening health complications and even death. Tetanus, for instance, causes painful muscle stiffness and can lead to difficulty opening the mouth, swallowing, and breathing. Diphtheria results in a thick coating at the back of the throat, causing breathing difficulties, heart failure, paralysis, or death. Pertussis, also known as whooping cough, induces violent coughing that makes breathing, eating, and drinking difficult. It is extremely dangerous for infants and young children, increasing their risk of pneumonia, convulsions, brain damage, and even death.
Tdap vaccines are typically administered to children between the ages of 11 and 18, preferably at 11 or 12 years old. Adults who did not receive the Tdap vaccine during adolescence should get at least one dose. Additionally, pregnant women are advised to get a Tdap dose during each pregnancy, ideally in the early part of the third trimester, to protect their newborns from pertussis.
Tdap vaccines contain a combination of vaccines in a single shot. The uppercase "T" and "d" in Tdap indicate a full-strength dose of tetanus and a reduced dose of diphtheria, respectively. On the other hand, the lowercase "p" signifies that the vaccine uses a smaller dose of pertussis. Tdap vaccines are generally safe, with mild side effects like pain, redness, or swelling at the injection site, nausea, vomiting, and stomachaches. However, severe allergic reactions are extremely rare.
Tenivac®, a Td vaccine, does not contain the pertussis component found in Tdap vaccines. Instead, it is a booster shot that immunizes against tetanus and diphtheria and is recommended for adults every 10 years. Each 0.5-mL dose of Tenivac contains ≤5.0 µg of residual formaldehyde, which is lower than the ≤100 µg of formaldehyde found in some Tdap vaccines like Infanrix®.

Tenivac® is sold by Sanofi Pasteur
Tenivac® is an immunization against tetanus and diphtheria for people aged seven and above. It is sold by Sanofi Pasteur and has been since 2003. It replaced Decavac®, an older Td vaccine that was discontinued in 2012. Tenivac is a Td vaccine, meaning it prevents tetanus and diphtheria but not pertussis. Tdap vaccines, on the other hand, prevent all three.
Tenivac is a booster shot that is recommended every 10 years. It contains a full-strength dose of tetanus (T) toxoids and a lower-strength dose of diphtheria (d) toxoids. Each 0.5-mL dose of Tenivac contains 5 Lf of tetanus toxoid and 2 Lf of diphtheria toxoid. Other ingredients per 0.5-mL dose include 1.5 mg of aluminum phosphate (0.33 mg of aluminum) as the adjuvant and ≤5.0 µg of residual formaldehyde.
Formaldehyde is present in Tenivac in a concentration of less than 5 mcg. This is comparable to the concentration in the generic Td vaccine, which contains 0.02% formaldehyde. Other Tdap vaccines, such as Infanrix® and Pediarix®, contain higher concentrations of formaldehyde (≤100 µg).
In addition to formaldehyde, Tenivac contains modified Mueller-Miller casamino acid medium without beef heart infusion and ammonium sulfate. It also contains natural rubber latex in the tip cap of the pre-filled syringe, which can trigger allergic reactions in people with a latex allergy.
