Clinical trials will be carried out in the UK to verify the safety and effectiveness of two new coronal vaccines under development by injecting them into the respiratory tract. The two vaccines, developed by Imperial College and Oxford University, are being tested intramuscularly.
Imperial College London said in a statement 14, the test personnel will spray the vaccine into the subjects’ mouth, directly acting on the respiratory tract, testing the safety and effectiveness. Christopher Chiu, an expert in infectious diseases at Imperial College of technology, who conducted the inhalation clinical trial, said that influenza vaccine injected from the nasal cavity has been proved to be effective, and it is necessary to study whether the new crown vaccine can also work directly on the respiratory tract. Compared with the systemic immune response induced by intramuscular injection, injection of the new crown vaccine into the respiratory tract may trigger local and more specific immune responses, the statement said. On the other hand, the dose of intramuscular immunization is smaller than that of the previous studies. The researchers are recruiting 30 healthy volunteers, aged 18 to 55. The trial is due to start in London in a few weeks. Focus
