I have had all the shots and boosters for whooping cough, but have been exposed to it by a friend's mother who unknowingly had it. chances of getting?

Some info: The vaccination provides good immunity against whooping cough, but there still can be cases among vaccinated individuals. The illness can be less severe if you have been vaccinated. Here is a good link for more information: http://www.cdc.gov/pertussis/fast-facts.html

Contact local doc: Your risk is minor, but you may want to contact your doc. Sometimes local health departments advise preventive treatment in some exposed persons so they don't become unwitting carriers of a mild case. This varies by local and level of exposure.It may also depend on your level of contact with others. (like small babies)
