The Murray Microbiology book says that it is prefentially 10 years, similarly Estonian and Finnish health associations.
However, my professor says that it can be 5-7 years.
I started to think if the age is affecting here to the result.
When should you take booster vaccination of Pertussis if you are a) 25 years old, b) 50 years old, c) 70 years old, and d) 90 years old?
My professor says that there is no significant studies about the efficacy of Pertussis booster vaccination among different age groups. Is this true?
