The\u00a0Covid-19\u00a0vaccines closest to the finish line are designed to be injected into the arm. Researchers are looking at whether they can get better protection from inoculations that fight the virus at its point of attack \u2014\u00a0the nose and mouth.<\/p>\n\n\n\n
Most vaccines in human testing require two shots for effectiveness, and developers still aren\u2019t even sure if they\u2019ll prevent infections. Scientists are hoping to generate superior immune responses with inhaled vaccines that directly target the airway cells the virus invades.<\/p>\n\n\n\n
An alternative to conventional jabs, sprayed and inhaled immunizations under development in the U.S., Britain and Hong Kong could play an important role in helping society escape restrictions that have\u00a0upended economies\u00a0and everyday life. Among their goals is to prevent the pathogen from growing in the nose, a point from which it can spread to the rest of the body, and to other people.<\/p>\n\n\n\n
\u201cLocal immunity matters,\u201d said\u00a0Frances Lund<\/a>, a University of Alabama at Birmingham immunologist working with biotech\u00a0Altimmune Inc.\u00a0on an early-stage nasal inoculation. \u201cThe vaccines that can be delivered to generate that will have some advantages over vaccines that are delivered systemically.\u201d Read more…<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" The\u00a0Covid-19\u00a0vaccines closest to the finish line are designed to be injected into the arm.
