Atlanta - Hundreds of thousands of vaccine against swine flu in children produced by the French pharmaceutical company Sanofi Pasteur has been recalled because tests indicated doses of vaccine has lost some strength, the government health authorities said Tuesday .The recall of about 800,000 pre-filled syringes for young children, aged 6 months to almost 3 years.
Shoots were distributed across the country last month and most have already been used by the federal Centers for Disease Control and Prevention. Physicians were notified of the voluntary recall Tuesday.
Dr. Anne Schuchat expert flu CDC stressed that parents have nothing to do or to worry. The vaccine is still safe, "she said. The issue is the healing force.
"No action (s) required a parent to a child who received the vaccine," said Tom Skinner, a spokesman for the CDC. "(The thing), they only need to do is make sure their children receive two doses if they are 6 months - 35 months age group, the group affected by the recall.
Tests before the shoots were presented showed that the vaccines were NOK strong. But tests conducted weeks later showed the force had fallen slightly below the levels required. Why does the power decrease is unclear.
Children in this age group is expected to receive two doses, spaced about one month apart. Health officials do not think they should be vaccinated again, even if they have had two doses of the same mass, Schuchat said.
Vaccine against swine flu has been available since early October, and since then manufacturers have released about 95 million doses for distribution in the United States.
The fire has been recalled by Sanofi Pasteur, the vaccines division of France-based Sanofi-Aventis Group. The company reported findings of activity to government officials and gave a voluntary recall.
A representative from Sanofi Pasteur was not immediately available for comment Tuesday. Sanofi Pasteur himself invoices No. 1 as a manufacturer of flu vaccines in the world. This makes the vaccine against flu to locations in France and Pennsylvania.
