"Researchers have been working to develop a vaccine that provides long-term, reliable protection from malaria. An effective vaccine could protect people living in malaria-endemic regions as well as travelers and military personnel.
(tetanus and diphtheria toxoids adsorbed) for Intramuscular Injection
DECAVAC®, Tetanus and Diphtheria Toxoids Adsorbed (Td), manufactured by Sanofi Pasteur Inc. for intramuscular injection, is a sterile suspension of alum (aluminum potassium sulfate)-precipitated toxoids in an isotonic sodium chloride solution. The vaccine, after shaking, is a turbid liquid, whitish-gray in color.
Corynebacterium diphtheriae cultures are grown in a modified Mueller and Miller medium.1 Clostridium tetani cultures are grown in a peptone-based medium containing an extract of bovine muscle tissue. The bovine muscle tissue used in this medium is US sourced. Tetanus and diphtheria toxins produced during the growth of the cultures are detoxified with formaldehyde. The detoxified materials are then separately purified by serial ammonium sulfate fractionation and diafiltration, and adsorbed onto alum.
Each 0.5 mL dose of DECAVAC (tetanus and diphtheria toxoids adsorbed) vaccine is formulated to contain the following active ingredients: 5 Lf of tetanus toxoid and 2 Lf of diphtheria toxoid. The tetanus and diphtheria toxoids induce at least 2 units and 0.5 units of antitoxin per mL of serum, respectively, in the guinea pig potency test. Each 0.5 mL dose also contains a trace amount of thimerosal [mercury derivative, ( ≤ 0.3 μg mercury/dose) not as a preservative] from the manufacturing process, aluminum adjuvant (not more than 0.28 mg aluminum by assay), and not more than 100 μg (0.02%) of residual formaldehyde.

What are the possible side effects of this vaccine (Decavac (Td), Tetanus-Diphtheria Toxoids, Adult (Td))?
You should not receive a booster vaccine if you have had a life-threatening allergic reaction after the first shot.
Keep track of any and all side effects you have after receiving this vaccine. When you receive a booster dose, you will need to tell the doctor if the previous shots caused any side effects.
Becoming infected with tetanus or diphtheria is much more dangerous to your health than receiving the vaccine to protect against these diseases. Like any medicine, this vaccine can cause side effects, but the risk of serious side...
