Sanofi Aventis retira 4 lotes de vacunas defectuosas contra el H1N1

Y eran para niños de 3 años o menos, no los revacunaran pero la vacuna en esos lotes es menso potente de lo que debía ser, es decir le meten porquerias al cuerpo que ni te salvan y a lo mejor hasta te contaminan.

WASHINGTON (Reuters) - Vaccine maker Sanofi Pasteur is recalling four lots of its pediatric H1N1 swine flu vaccine because it is not as potent as it should be, U.S. officials said on Tuesday.

There is no safety concern, and children vaccinated from the lots already will not need to be re-vaccinated, the U.S. Centers for Disease Control and Prevention said.
The affected vaccines are pre-filled syringes for children under 3, the CDC said.
