The nasal vaccine provides sterile immunity, allowing the pathogen to interrupt the chain of transmission. RAS academician and head of the Gamaleya Center Alexander Gintsburg told socialbites.ca that this is a fundamental problem in epidemiology that has never been solved.
“The nasal vaccine offers fundamentally new opportunities. Since it is given into the nose, it provides sterile immunity. This means that the person vaccinated in this way will no longer be a carrier of the pathogen. And the person vaccinated by injection. That is, he protects himself, but can release the virus from the nasopharynx and infect others. Therefore, from an epidemiological point of view, it breaks the chain of transmission “The thing is the vaccine taken through the nose,” the scientist explained.
According to Gunzburg, such vaccines can now only be made based on adenovirus. That is why it is so important that the updated Sputnik V, based on Omicron’s (Kraken) XBB.1.5 variant, is also released in nasal form. Clinical trials of a new version of the drug are currently ongoing; will enter civilian circulation no earlier than March next year.
“We are currently conducting clinical trials of the updated Sputnik based on “It means that we will push back the date of its introduction into civilian circulation by 2.5 months. In other words, the new Sputnik will enter civilian use in March,” he explained.
