Tetanus
- caused by bacteria or virus?
- affects which part of the body?
- incubation period
- manifestation

Pertussis
- caused by bacteria or virus?
- manifestation

- onset similar to upper resp. infection, progress to severe coughing spells leading to diff breathing, vomiting, wt. loss, incontinence, rib fx, passing out from violent coughing.
“100 day cough”
Are whole cell pertussis vaccines used anymore?
no..
What do the capital and lower-case letters mean?
Upper-case letters denote full-strength doses of diphtheria (D) and tetanus (T) toxoids and pertussis (P) vaccine. The “a” in DTaP and Tdap stands for “acellular,” meaning that the pertussis component contains only a part of the pertussis organism
– Lower-case “d” and “p” denote reduced doses of diphtheria and pertussis used in the adolescent/adult-formulations.
What does DTaP stand for and in when are the boosters given?
(Tdap?)
