The UK will test the inhaled new crown vaccine

uk will conduct clinical trials of two new crown vaccines by spraying the respiratory tract to test the safety and vertase of this application.
two vaccines, developed by Imperial College and Oxford University in the UK, are currently in the process of clinical trials of intramuscular injections.
Said in a statement Thursday that the testers will spray the vaccine into the subjects' mouths, directly acting on the respiratory tract to test safety and effectiveness.
Christopher Qiu, an infectious disease specialist at Imperial College who is leading the inhalation clinical trial, said the flu vaccine sprayed from the nasal cavity has been shown to be effective and needs to be studied to see if the new corona vaccine works directly on the respiratory tract.
a new corona vaccine to the respiratory tract may trigger a local and more specific immune response than a systemic immune response triggered by intramuscular injections, the statement said. In addition, according to previous studies, inhalation is smaller than intramuscular injections in terms of the dose of vaccine required to trigger an immune response.
are recruiting 30 healthy volunteers between the ages of 18 and 55. The trial is scheduled to begin in London in a few weeks.
