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.

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”.

    Interferon is named as such because when you have a virally infected cell, it will secrete it to interfere with the process. It knocks on the cell’s next door neighbor to say that shit’s fucked and you need to prepare. So the cell will close its windows, uptake less, etc. in an effort to be alert to stop the spread.

    It still surprises me that you can do recombinant drugs without your body freaking out. Recombinant is when you put the gene (i.e. DNA) for interferon in an E. coli or yeast or something to harvest a bunch of it. The whole schtick of your immune system is deciding what’s foreign and what’s host. It’s like if a little alien knocked on your door and told you a different, mean alien is running around, so you need to lock your doors. You look at them in the eyes posad , blink twice, and go “sure!”

        Sure, you’re putting a human gene in there, but the subtle part of it is that when you have to recognize something as foreign, your cells chop up a protein and present IIRC 8-12 amino acids to present for immune cells (mhc-1). In that sense, the body is really sensitive to what proteins look like. I would imagine it not accepting a document that was .pdf instead of .docx. So when the protein is synthesized via recombinant means, I would expect some small change - if not even in terms of AA sequence (which Cuban scientists no doubt had to test for) then some glycosylation or other alterations that a bacteria would do.

        The method isn’t brand new or anything, I believe insulin can be made that way (not checking), it’s just a marvel of science to me

        These is at a higher dose but gives you a sense:

        Although frequently effective, IFNα induces a variety of neuropsychiatric adverse effects, including an acute confusional state that develops rapidly after initiation of high-dose IFNα, a depressive syndrome that develops more slowly over weeks to months of treatment, and manic conditions most often characterised by extreme irritability and agitation, but also occasionally by euphoria. Acute IFNα-induced confusional states are typically characterised by disorientation, lethargy, somnolence, psychomotor removedation, difficulties with speaking and writing, parkinsonism and psychotic symptoms. Strategies for managing delirium should be employed, including treatment of contributing medical conditions, use of either typical or atypical antipsychotic agents and avoidance of medications likely to worsen mental status. Significant depressive symptoms occur in 21–58% of patients receiving IFNα, with symptoms typically manifesting over the first several months of treatment. The most replicated risk factor for developing depression is the presence of mood and anxiety symptoms prior to treatment.

        A vaccine trains your immune system to respond, and interferon therapy is throwing the immune system into DEFCON 1

        Useful and an achievement for Cuba but still worse than other social interventions

        Cases would exhibit some seasonality instead of going to zero for years of new variants

        This is not unique to Cuba of course

        And of course, even China eventually succumbed to “letting it rip” instead of eradication which was, at one point, actually feasible.

          I suppose ‘feasible’ is a subjective word, but eradication is still possible, and is a proletarian aim. China was being sadly ahead of it’s time, but in so doing showed the world a model for it
