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.
Vaccination is the only way to protect against tetanus. Due to widespread immunization, tetanus is now a rare disease in the US. A combination booster vaccine, called Tdap, protects against tetanus, diphtheria, and pertussis (whooping cough). Tdap should be given to all adults once in place of one Td (tetanus-diphtheria) booster vaccine, which is recommended every 10 years. Adults who were never fully immunized against tetanus should start with a three-dose primary series given over seven to 12 months.
