NASHVILLE, Tenn. - On Tuesday, the manufacturer Sanofi recalled nearly one million H1N1 vaccination doses, and 82,600 of those are in Tennessee.
Weeks ago, parents and their children were some of the first in line for the H1N1 vaccine. The same mothers and fathers have learned that 82,600 injectible vaccines meant foinjectableonths to 3 years old have been recalled from Tennessee.
Health officials said what sounds like cause for concern is not.
"The vaccine was manufactured; it met all standards of the FDA and then was released for use. The manufacturer tests the vaccine monthly thereafter, and they discovered to their surprise that the amount of potency had diminished somewhat," said Dr. William Schaffner with Vanderbilt University Medical Center.
State Health officials said this can happen but that it's very rare.
"A vaccine can lose its potency because of the fragility of the vaccine," said State Health Commissioner Susan Cooper.
Officials are not sure exactly where the affected vaccines ended up, but they do know that if your child ended up with one, they're still protected against H1N1.
"There's extra punch in the vaccine, so even though the amount has diminished - the children who got this vaccine do not need to be revaccinated. They got plenty of vaccine," said Dr. Schaffner.
Even though it's still effective, the manufacturer is recalling the vaccine because it did not meet the high standard potency level.
Doctors said children do not need a replacement for the first or second dose, but that parents should make sure they get a follow up dose no matter what.
Health officials in Davidson County and Shelby County confirmed they did not receive affected doses. State Health Officials are working to confirm how many of the more than 80,000 doses came from affected lots.
