Re: interesting pertussis research

[Guest guest]

This part made me absolutely sick:To protect infants in the long term, it may be more effective to start vaccination earlier in life.The cocooning immunization strategy focuses on vaccination of family members and other adults in close contact with the infant. Pertussis booster vaccination during the third trimester of pregnancy is another interesting approach that should, however, be studied in more

detail. http://www.medscape.com/viewarticle/752974I 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._Sheri Nakken, former R.N., MA, Hahnemannian Homeopath Vaccination Information & Choice Network, Washington State, USAVaccines - http://vaccinationdangers.wordpress.com/ Homeopathy http://homeopathycures.wordpress.comVaccine Dangers, Childhood Disease Classes & Homeopathy Online/email courses - next classes start May 8 & 10 & 15
