In particular, Kommersant wrote about this.

Chulanov said that, according to the instructions for Sputnik V, the drug can be administered both intramuscularly and intranasally, using an atomizer nozzle. “Clinical studies have shown a favorable safety and immunogenicity profile, i.e. — the effectiveness of the vaccine both intramuscularly and nasally,», — he pointed out.

According to the chief infectious disease specialist, when administered through the nose, “Sputnik V” forms mucosal immunity (immunity of the mucous membranes of the body) against COVID-19 on the surface of the mucous membrane of the respiratory tract and stimulates the immune response in the regional lymph nodes and tonsils. “This creates a protective barrier to entry gates of infection (nose and oropharynx). It is here that the organism first encounters the virus. Chulanov emphasized.

The Health Committee of the Kursk region also told RBC that the use of “Sputnik V” for nasal vaccination in the region complies with the instructions approved by the Ministry of Health. “It is allowed to administer the vaccine intranasally using a dosing device (spray nozzle on a vertical type syringe on a vertical type syringe for nasal administration of drugs)”, — stated in the current version of the document.

The Ministry registered the nasal vaccine “Gam-COVID-Vac” (Sputnik V), which the agency claims is the world's first vaccine in this format, on April 1. The drug is allowed to be used only for vaccination of patients over 18 years of age. The spray vaccine is the second component of Sputnik V. April 8, the head of the Center. Gamalei Alexander Gintsburg said that the drug was released into civilian circulation and was transported to the regions. In the winter, Gunzburg said that experts did not yet have data on 100% protection with a nasal vaccine, so it was recommended to inject Sputnik V along with it.

In mid-August, the head of the Kursk Health Committee, Ekaterina Pismenny, said that the region was the first in Russia to massively launch nasal vaccination against COVID-19.

However, Kommersant This week I wrote that during vaccination in the region they use not a nasal, but a regular drug, which is injected into the nose with the help of special nozzles. Nikolai Kryuchkov, an expert in the development and research of drugs, said in a conversation with the publication that from a medical point of view, both a separate vaccine and the usual Sputnik V can be used internally, but legally these are different drugs. “According to the regulatory rules, you can’t just take a vaccine for intramuscular injection, open it, remove the protective cap, change it to a nozzle— and get a new drug, — he said.

In turn, Doctor of Biological Sciences, Professor Konstantin Severinov believes that it is impossible to use a drug intended for intramuscular injection internally: “Any change in the form of drug use will most likely require a dose change. And it needs to be calculated in the course of research.

On August 10, the Ministry of Health announced that the expiration date of Sputnik V extended and range from six months to a year for drugs from different manufacturers. The commentary of the ministry, received by RBC, says: “If the regulator decides to increase the shelf life, this means that the safety, efficacy and quality profile of the drug has not decreased over a certain period of storage.” The department also indicated that, given the short lead times for vaccine development, this practice has been repeatedly used in the European Union and the United States— regions with “strict” regulatory agencies according to the classification of the World Health Organization.
