BROOKLYN - The Centers for Disease Control and Prevention announced Tuesday the recall of 800,000 doses of the swine flu vaccine.

According to the CDC, the doses produced by Sanofi Pasteur are being recalled not because they are harmful, but because they are not strong enough to provide protection against the H1N1 virus.

The vaccine, packaged in pre-filled syringes, was intended for young children between the ages of 6 months and 3 years.

Health officials say it is recommended the children who received the weak vaccines get a second dose about 28 days after the first in order to be fully protected.
