In the second such recall this season, manufacturer MedImmune says the vaccine has lost potency since it was made. 'This is not a safety issue,' a U.S. official says. Vaccine maker MedImmune has voluntarily recalled 13 lots of vaccine against the pandemic H1N1 influenza because they have lost some potency since they were manufactured, the company said Tuesday.
