The Montgomery County Health District reports that some residents of Dayton, Ohio may need to be revaccinated after being injected with an ineffective batch of H1N1 vaccine. Residents who turned out for the clinic held December 17 at Showcase Cinema and received the vaccine before 5:30 will need to be vaccinated again. Apparently, the vaccine had been frozen, which renders the drug defective. Health officials are now contacting those who received the ineffective vaccine.

Officials say that this is not a safety issue, and that all people receiving nasal mists and those who got the vaccine after 5:30 should be fine, but others will need to be revaccinated.

Defective drugs may have dangerous side effects, or they may be ineffective for performing their stated purpose. If you received a defective drug and suffered serious health effects as a result, you may be able to receive compensation. Please contact the pharmaceutical injury lawyers at Robert W.
