According to the publication, the sale of the nasal and throat spray against the coronavirus was due to begin on Monday, May 3. The spray can be bought at the pharmacies of the Estonian chain Benu.
Since Monday, much of Estonia’s restrictions to combat the spread of the coronavirus have been relaxed. The new spray is expected to help prevent a third wave of COVID-19.
There are no specific rules or restrictions regarding the use of the aerosol. It is suitable even for children under 7 years old. Parents of six-year-olds should consult a doctor about spraying into a child’s nose. The spray is also suitable for lactose intolerant people. One of the contraindications is allergy to milk proteins.
“This is by no means a spell, but the purest chemistry,” Ustav assured, adding that it was necessary to spray the drug before meeting other people, playing games before going to work, sitting in public transport, visiting a store. , etc.
The technology, which enabled the production of antibodies against SARS-CoV-2 from nasal and throat sprays, is the result of a collaboration between three companies and two universities.
The name of the spray is SARS-Cov-2 BioBlock. As early studies show, it is effective in protecting against coronavirus.
Professor M. Ustavas, who led the development of the technology, pointed out that the basis of the aerosol is a preparation made from the colostrum of hyperimmunized cows. Researchers have been able to invent methods that can be used to isolate antibodies and produce a coronavirus aerosol in colostrum.
The professor emphasizes that SARS-Cov-2 BioBlock is not an anti-COVID-19 drug, but an antiviral agent that acts on the nasopharyngeal mucosa and it is at this site that it inactivates the SARS CoV-2 viruses that cause COVID- 19.
The professor stressed that the antibodies used in the manufacture of the spray exceed not only the original type of coronavirus, but also newer strains of it, originating from Great Britain, South Africa and Brazil.
Animal testing has shown that antibodies in the nose an hour before a high dose of SARS-CoV-2 virus enters results in a significantly lower viral load in the lungs. This means that the new spray entering the nasopharynx can trap SARS-CoV-2 and render the viruses harmless.
Ruth Oltjer, Director of Chemi-Pharm, previously mentioned the upcoming clinical trials and the subsequent start of production as soon as possible.
The spray can be useful not only in places where it is difficult to maintain a safe distance from other people, but also when a family member living together becomes infected with the virus. The drug can also be helpful for infected people, as it reduces the risk of infection in other people.
However, the aerosol cannot replace vaccines or protective masks. It’s just a complement to even more effective protection against the spread of the coronavirus.
Icosageni Grupp, Chemi-Pharm, Teadus ja Tegu, as well as the Estonian University of Life Sciences and the University of Tartu, contributed to the development of SARS-Cov-2 BioBlock.
