Guest guest Posted April 4, 2001 Report Share Posted April 4, 2001 <<In fact, protection againstwhooping cough declines three to five years after vaccination with whole-cellpertussis vaccine and disappears after 12 years.>> I find this statement particulary fascinating due to the fact that many children " outgrow " their asthma problems as teenagers- a connection I wonder? It will be interesting then, to see what happens when these same kids are re-injected again and again.... CherylO in MI Quote Link to comment Share on other sites More sharing options...
