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.
Booster vaccines needed to keep up protection from tetanus. The DTaP does not offer lifetime protection. People need booster vaccines to keep up protection from tetanus. Children should get a booster vaccine called Tdap (which protects against tetanus, diphtheria, and whooping cough) at 11 or 12 years of age. Adults need a booster called the Td vaccine (for tetanus and diphtheria) every 10 years. Adults should also receive a one-time shot of the Tdap vaccine in place of one Td shot.
