The answer, it seems, in another early look at the data, is yes. Even a single dose of the watered-down version of the vaccine produced enough antibodies to protect against infection in 80% of the 175 people studied...
...borne out, the results suggest that more vaccine may be available for more people and that more people could be protected against H1N1 sooner. If only a single dose is required, that means vaccines could yield protection within three to four weeks after inoculation, instead of the six to eight weeks it would take if two doses were needed...
