The journal Nature Microbiology published, in its April 3 issue, stating that the next booster doses of Covid-19 vaccines will be administered in the nose, instead of the arm.
She pointed out that a team of German researchers tried administering a vaccine for Covid-19 to hamsters in the laboratory, through the nose. They found that this aerosolized vaccine performed better than injected mRNA vaccines. It protected Delta hamsters. The researchers said that they see a valuable opportunity to generalize the use of a vaccine that is sprayed through the nose to provide immunity from the new Corona virus mutants that are expected to appear in the future. The problem with current vaccines (Moderna, Pfizer-BioNTech, Johnson & Johnson) is that it takes a long time for them to do their job of destroying the virus before it causes the expected damage. Scientists say that finding a vaccine that is sprayed into the nose will be more capable of achieving the task, because the SARS-CoV-2 virus begins its journey of invading the infected body from the nasal mucosa and respiratory system. And if the new vaccine is able to prepare immune cells in the nose, throat and lungs, then its effect will be faster than the vaccine, which begins its journey of effectiveness from the arm, the injection site, and then crosses the bloodstream. India and China had approved two vaccines to be sprayed in the nose. Data indicates that there are more than 100 inhaled vaccines undergoing clinical and laboratory trials around the world. In addition to the desired benefit for those who are afraid of being stabbed with vaccine needles; The hope is high that the performance of the inhaled vaccine will be more effective than the doses injected into the muscles, in treating a respiratory disease such as Covid-19.
