A chromosome (from Greek: ÏÏá¿¶Î¼Î± color and Ïá¿¶Î¼Î± body) is a packaged and organized structure containing most of the DNA of a living organism.
Diphtheria, tetanus and pertussis are prevented by a childhood vaccine, called DTaP, and a newer vaccine for adolescents and adults, called Tdap.
There are two important ways to prevent tetanus: Tetanus immunization is part of the DTaP (diphtheria, tetanus, and acellular pertussis) vaccinations. Kids usually receive a series of four doses of DTaP vaccine before 2 years of age, followed by a booster dose at 4 to 6 years of age. After that, a booster (Tdap) is recommended at 11 to 12 years of age, or later if it was missed, followed by a tetanus and diphtheria booster every 10 years through adulthood. The Tdap vaccine is also recommended for all pregnant women during the second half of each pregnancy, regardless of whether or not they had the vaccine before, or when it was last given.
