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.
Everyone needs protection from tetanus. The DTaP vaccine (diphtheria, tetanus, and pertussis) can help prevent tetanus in young children. DTaP shots are recommended for healthy babies at ages 2, 4, and 6 months, and again at 15 through 18 months. A DTaP booster is recommended for children ages 4 through 6 years old. Because immunity to tetanus decreases over time, older children need to get the Tdap vaccine.
