This is but another example of the Globe's failure to fully report the benefits and risks of an intervention.

Only the relative ratio, 69%, of babies with inoculated mothers will avoid whooping cough; this could be an infinitesimal number only known if the article had included the absolute benefit and the absolute risk.  There is also no link to the study so one can make their own assessment.

Instead the are essentially presenting an endorsement of an intervention that may provide  no benefit at all except to the manufacturers of the vaccine.  

They have to do a much better job of presenting the evidence when publishing these articles otherwise they should be taken with a grain of salt.
