Injection-free vaccinations developed with the help of the Gates Foundation



Researchers have proved that "injection-free" vaccines are an effective tool in the fight against diseases. The team, based in King's College London and funded by the Bill & Melinda Gates Foundation, used dried sugar to create a microneedle array — a tiny disc that only lightly perforates the skin. The dried sugar, which was laced with an HIV vaccine, dissolves when inserted in to the skin, effectively delivering the vaccine and kick-starting an immune response. The method is far less invasive than conventional vaccines that are delivered via a hypodermic needle.
