GOLDEN, Colo. — June 3, 2021– A systematic review and meta-analysis published in the April 30, 2021 issue of The Lancet strengthens evidence from previous publications that fractional dose delivery is a viable alternative to full dose inactivated polio vaccine (IPV). Previous studies have shown that two doses of intradermally-delivered IPV (60% less vaccine) were more immunogenic than one full dose delivered intramuscularly. Intradermal fractional dose delivery also lowers the total cost of vaccination substantially.
