This really should be of no concern — either in the providers’ offices around the US, or on the NYSE, tomorrow. It affects only one lot; and presumably any damaged conjugate vials would be readily seen as cracked, upon the FDA-required visual inspection by the nurse, immediately prior to administration by injection (still an entirely manual process, thankfully, here).
Just the same, West Point, Pennsylvania is smart to fully recall the entire lot — for safety’s sake. I am certain there will be no impact on availability of the Hep B vaccine, as several weeks’ supply is already on hand, in finished goods, and wholesaler inventories, around the nation. Here’s a bit of the story from last Wednesday do go read it all:
. . . .Merck said Wednesday that it was recalling one lot of its hepatitis B vaccine Recombivax HB that was made in West Point, Montgomery County, because of fears that some of the vials could have cracked. . . .
The U.S. Food and Drug Administration posted a notice of the voluntary recall on its website. The medication is delivered via injection. . . .
