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.
It's usually OK to receive an extra booster of the tetanus vaccine. This is especially true if you're being treated for an acute injury, such as a deep cut or puncture wound. Vaccination is the best way to prevent tetanus â a serious disease caused by a bacterial toxin that affects the nervous system. Tetanus bacterial spores can enter your body through any cut or scratch. But deep puncture wounds, such as from stepping on a nail, are most susceptible to tetanus infection.
