Clarification of H1N1 Vaccine recall

The voluntary recall of H1N1 vaccine intended for young children doesn't mean the vaccine was unsafe or defective. Christine Stone, Communications Officer with the Oregon Public Health Division says the vaccine was not as potent as specs called for but would be effective enough to provide the anti-bodies needed to prevent H1N1 flu. Any children who may have been vaccinated by the 'under-strength' serum would not neccesarily need to be re-vaccinated, but Centers for Disease Control guidelines suggest that children nine and under receive a second dose about one month following the first one.

An earlier story was unclear and may have suggested that any child who received the low potency vaccine would have to be vaccinated again.
