Effective vaccines, without a needle: Since the start of the COVID-19 pandemic, researchers have doubled down on efforts to create patches that deliver life-saving drugs painlessly to the skin, a development that could revolutionize medicine.

The technique could help save children's tears at doctors' offices, and help people who have a phobia of syringes.

Beyond that, skin patches could assist with distribution efforts, because they don't have cold-chain requirements – and might even heighten vaccine efficacy.

A new mouse study in the area, published in the journal Science Advances, showed promising results.
