Scientists develop effective intranasal mumps-based COVID-19 vaccine candidate
New research has advanced COVID-19 vaccine work in several ways: using a modified live attenuated mumps virus for delivery, showing that a more stable coronavirus spike protein stimulates a stronger immune response, and suggesting a dose up the nose has an advantage over a shot. Researchers used a modified live attenuated mumps virus, illustrated above, to...
