Just wondering if anyone knows where I could find information on the likelihood or stats relating to the chances of a fully immunised toddler/pre-schooler getting Whooping Cough twice?? i.e. contracting it in a mild form in 2011 at 2.5 years old and then re-contracting it again a year later.
I'm about to try and google it but because it's a pretty obscure question, I don't like my chances of finding anything much and thought I'd tap into the awesome amount of knowledge in BB
TIA.
