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.
Tetanus vaccines prevent lockjaw, a disease of horrible muscle spasms that is generally fatal. If you have already been properly vaccinated within the last 10 years, then you are probably protected unless the puncture wound is profoundly contaminated--prompting a need for a booster vaccine in 5 years. The symptoms of tetanus can occur as quickly as 3 days, although the average is 8 days. In brief: Not long.
