Amador County Public Health received word yesterday that certain lot numbers of injectable pediatric H1N1 vaccine, indicated for children 6 months through 35 months, decreased in potency between shipment and current testing. “Most importantly, there is no safety issue associated with these lot numbers of the H1N1 vaccine and this dose does not need to be repeated,” affirmed Dr. Bob Hartmann, Amador County Health Officer. “This advisory does not apply to any of the nasal mist vaccine,” he said. Original testing revealed adequate strength, but in routine follow-up testing the antigen potency had dropped slightly below guidelines, prompting the request to return these doses to the manufacturer. “Although another dose to replace this vaccination is not necessary,” stated Lori Jagoda, Amador County Public Health Immunization Coordinator, adding: “all children under the age of 10 years will still need to receive their second dose of the H1N1 vaccine, available in January 2010.” A TSPN TV Report This email address is being protected from spambots.
