New CDC policy on polio vaccine

See Science 240:1145 (1988). It has long been known that the risk of
Vaccine Associated Paralytic Poliomyelitis is higher with the first dose. 
The oral vaccines are used because of their higher degree of protection,
the generation of IgA response and "herd immunity."  To use the killed
virus for the first dose only makes a lot of sense.  HOwever, the later
doses should still be the oral, attenuated live viruses.  The idea has been
around for a long time, the recommendation came in 1988: evidently it has
taken this long to make a change in policy.
