A new method of administering the inactivated poliovirus vaccine (IPV) may be on the horizon, thanks to the collaboration of multiple Australian research centres and institutions. A Nanopatch is a vaccination tool consisting of an closely-packed array of microneedles which, when placed on the skin, can deliver vaccine into many thousands of cells in the dermis. The Nanopatch may one day enable unprecedented levels of antigen sparing. Just 1/40th of a full dose is sufficient for administration of IPV by micropatch.
