Side effects in that group were compared with those in a second group of over 2300 infants not given HBV vaccines within the same timeframe.

Lewis and colleagues of Kaiser Permanente's Vaccine Study Center in Oakland, California. Study data were associated with infants seen at Kaiser's San Francisco Medical Center.
