For millions of people each year, the fear of a painful injection using a needle is enough to put off the next trip to the doctor indefinitely. But according to Celine Park, a student from the Royal College of Art, we might be able to use fungal inhalers to administer vaccines instead. The concept proposes that weakened forms of a virus can be attached to fungal spores, which travel to the bloodstream through the lungs when inhaled through the puffer. Because fungus organically contains weakened viruses, they seem like the perfect vessel to deliver vaccines. As an added bonus, the inhalers are brightly coloured and whimsical, which might help deliver vaccines to children that would otherwise be scared of a needle.
