Dear Institute of Environmental Science and Research Limited, I note the

And Whooping cough / pertussis
[3]https://web.archive.org/web/201501240838...

Would you kindly share the ethnicity and immunisation status information

If they are no longer published, would you please share the minutes, memos
correspondence, emails etc regarding the decision to remove this
information.

Yours faithfully,

Erika Whittome
