Right now, protection against Covid-19 comes via an injection. But in future, those vaccines could come from inhalers or even pills.

In a white, airy laboratory in Medicon Village, one of southern Sweden’s largest science parks, chemist Ingemo Andersson holds up a thin, plastic inhaler, half the size of a matchbox.

Her team is hoping this tiny product could play a big role in the global fight against coronavirus allowing people to take powdered versions of future vaccines at home.

Researchers are looking at easier ways for people to get the vaccine, including via inhalers and tablets.
