More than 90 percent of women who received the new vaccine produced significant antibodies against strep while only about 60 percent of women who received the old vaccine did.
Test-tube experiments showed antibodies culled from recipients of the new vaccine were powerful enough to kill strep.
It will take several years to develop a shot, especially since Kasper's vaccine fights just one of the five subtypes of Group B strep that exist.
North American Vaccine Inc. has licensed rights to Kasper's vaccine and is presently planning the research necessary to win Food and Drug Administration approval.
The company is working with the NIH to determine whether the vaccine would harm the fetus. The vaccine may possibly be used on teen-age girls, to give them antibody protection before they become pregnant.
