interesting pertussis research

I haven't read the whole thing yet, but this section caught my

eye:

A universal adolescent booster vaccination will reduce the incidence of

pertussis in the target group but the duration of immunity is uncertain.

It is an open question as to what extent boosters should be offered to

older age groups or if natural infections would be preferable. On the one

hand, circulating B. pertussis may be hazardous to the youngest

unvaccinated infants. On the other hand, subclinical natural boosters

might be beneficial to population immunity. As the duration of immunity

is shorter after vaccination than after natural infections, an unwanted

consequence of adolescent boosters might shift the infection peak to

older child-bearing adults. It is therefore recommended that recurrent

serosurveys are used to follow the influence of vaccination on the

antigenic pressure, as well as the duration of protective

immunity.
