H1N1 Recall, what you need to know

Posted Dec 15 2009 11:35am

Breaking News: What you need to know about the recalled H1N1 vaccine!


Q. Which vaccine has been recalled?

The Sanofi-Pasteur brand of single-dose, pre-filled syringe, preservative free H1N1 vaccine for children 6 months to 3 years of age is the vaccine being recalled. Specifically, there are four batches (“lots”) being recalled.


Q. Why is this vaccine being recalled?

As part of routine testing, the manufacturer found that these four batches or lots may not be potent enough for a person to mount an adequate immune response. The vaccine is NOT being recalled for a safety issue.


Q. Which batches of the vaccine are the ones in question?

They are: UT023DA, UT028DA, UT028CB, and UT030CA.


Q. How will I know if my child received one of these batches of vaccine?

Well, for starters, your child must be between 6 months to 3 years of age to get this vaccine. And, if you know your child received the thimerosal preservative free vaccine, it is possible he got one of these batches. You can call the medical facility where your child was vaccinated as providers must document in a medical record which lot of vaccine was administered.


Q. Will my child need to get another dose of H1N1 vaccine if he already got one or two shots with these affected batches or lots of vaccine?

No. Your child should have adequate protection because the potency is only SLIGHTLY below acceptable concentrations known to be effective in providing an adequate response.


Q. If my child already got one dose of the H1N1 vaccine, does he need a second dose?

Yes, if your child is under 10 years of age. Regardless of which batch or lot of H1N1 vaccine he received, he needs two doses given at least 21-28 days apart to provide protection from H1N1 disease. And no, it’s not too late! There are other H1N1 injectable vaccine options for kids ages 6 months and up.
