Speaking of dishonest and disingenuous statements. No where does MR or myself indicate anti-vax positions. Various Quotes follow: "We know from statistics that about half of cases of whooping cough in young children are caught from the parents. "So it is best practice to give women whooping cough vaccinations, ideally during the pregnancy or immediately after delivery. Department of Health spokesman Gary Dowse said whooping cough was still common in the community. "It occurs in all age groups and hence little babies can catch it from their parents, from their grandparents, from their siblings," he said.

As a result, B. pertussis infections are endemic in adult populations. The future control of B. pertussis will require immunization schedules with new acellular vaccines that include booster doses in older children and adults. http://jid.oxfordjournals.org/content/174/Supplement_3/S259.full.pdf Women in their last trimester of pregnancy are recommended to receive a pertussis-containing vaccine if there has been an interval of five years or more since a previous dose and the expected date of delivery. http://www.health.vic.gov.au/chiefh...isory-2015-01-increase-in-pertussis-cases.htm The reasons for this are thought to include waning vaccine-induced immunity; better awareness of the disease; increased testing, including greater availability of more sensitive PCR diagnostic tests; improved reporting and surveillance; and changes in the organism itself. It is also thought that acellular pertussis vaccine, introduced in Australia in 1999, may not confer as long-lasting immunity as that provided by the whole cell vaccines used previously. http://www.health.wa.gov.au/disease...g_pertussis_epidemic_in_Western_Australia.cfm Point being YOU have no idea where this child picked up whooping cough from.
