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.
Vaccines are available that can help prevent tetanus, an infection caused by Clostridium tetani bacteria. Tetanus vaccination is recommended for all babies, children, teens, and adults. DTaP and DT are given to children younger than 7 years old, while Tdap and Td are given to older children and adults.
