Scientists develop new inhaled COVID-19 vaccines

A total of 14 COVID-19 vaccines are now in some degree of use across the world, all of them injected into your arm. 

But for cold storage requirements and other reasons, ​some of these drugs may not be the best fit in less accessible parts of the world.

So scientists are working on ​a new ​class of vaccines that would be inhaled, not injected.
