It modulates the response to the virus at the level of the immune system, and is used to treat an infection.
We conducted an experimental protocol with a nasal recombinant IFNα-2b formulation (Nasalferon) in 12 healthy volunteers who received 1 MIU per nostril twice a day, three consecutive days, and studied the induction of biomarkers related to antiviral and immune responses. Nasalferon increases the antiviral biomarker OAS1 transcript levels in oropharynx and PBMCs, regulates molecular and cellular elements related to innate and adaptive immune responses and decreases granulocytes population. These effects support Nasalferon use in virally-exposed populations.
Cuba will start applying Nasalferon to travelers and live-in family members
In Cuba, All International Travelers to Receive Nasalferon
Meanwhile "free" countries are destroying the lives of millions of people by pretending covid doesn't exist anymore, and paxlovid is $1000 dollars and doctors don't want to prescribe it because covid is "mild".
Cuba pound-for-pound best country.
