Specialists suggest spraying the drug in the nasal cavity.
As part of the scientific work, experts have compared several ways to introduce a vaccine against COVID-19.
The experiment was conducted on golden Syrian hamsters. In the course of the study, the scientists administered the drug to individuals in two ways: intranasal and intramuscular.
AstraZeneca vaccine, developed by specialists from Great Britain, was tested.
The results of the experiment showed that both methods of administration of the coronavirus vaccine resulted in a stable immune response.
However, the method of intranasal administration proved to be more effective.
WHO declared COVID-19 pandemic in March 2020. According to recent data, more than 67.7 million people were infected with coronavirus during the entire period of spread.
