Future of COVID vaccines could be nasal sprays, patches

The future of COVID-19 vaccines might not be shots in the arm or leg. Instead, picture a nasal spray or a patch stuck onto the skin for a few minutes.

A group of scientists, doctors and administration health officials gathered at the White House on Tuesday to discuss the next generation of inoculation against COVID and its viral cousins; they were in agreement that there is room for improvement.

The future could include vaccines that protect equally against all variants -- or even vaccines that stop infections from happening in the first place.
