Let's use DEFECTIVE INTERFERING PARTICLES (DIPs) to REDUCE the REPLICATION of SARS-CoV-2 👍

DIPs are virus-like particles that arise during virus growth, fail to grow in the absence of virus, and replicate at the expense of virus during co- infections. Image
2) DIPs have been studied as potential antiviral agents against a variety of RNA viruses, including influenza, measles, and respiratory syncytial virus (RSV). They have shown promise in both in vitro and animal models, demonstrating their ability to reduce viral replication ... Image
3) ... and improve disease outcomes.
Here is for example a study about their use against the dengue virus

"Dengue virus-free defective interfering particles have potent and broad anti-dengue virus activity" nature.com/articles/s4200…
Image
4) In 2021, researchers have reported their attempt to engineer TIPs that can conditionally replicate with SARS-CoV-2, inhibit viral replication 10–100 fold.
To this end, the TIPs inhibit the virus through competition for viral replication machinery. Image
5) In their work, a single dose administration of TIP ribonucleic acid (RNA) was found to inhibit SARS-CoV-2 in continuous cultures.

6) In a very interesting study just published, they explored "the therapeutic potential of defective interfering particles in reducing the replication of SARS-CoV-2"

Image
6) I find this idea of ​​"parasitizing" the replication of SARS-COV-2 quite fascinating.

Let's DIG into DIPs and TIPs 🤗
maybe a therapy of the future.

The HIDDEN SECRET 🤫 about VACCINES ? The ADJUVANTS

New technologies such as mRNA are more attractive than a product such as an adjuvant that is added to a vaccine. And yet, without adjuvant, the effectiveness of vaccines would be much less. Image
2) The subject was discussed a little, about the Novavax vaccine and the rather remarkable effectiveness of its Matrix-m adjuvant.

Image
3) Then, the subject was quickly forgotten, despite numerous studies showing the important role played by these adjuvants.

SARS-COV-2 is AIRBORNE !!!

Transmission in a movie theater in Korea, nov. 2021

RESULTS: Of the 48 confirmed cases, 35 were theater attendees (72.9%), 10 were family members of attendees (20.8%), 2 were friends (4.2%), and 1 was an employee (2.1%). ophrp.org/journal/view.p…
Image
2) Among the 80 individuals who attended the 3rd to 5th screenings of the day, 35 became infected, representing a 43.8% attack rate. Specifically, 28 of the 33 third-screening attendees developed confirmed SARSCoV-2, constituting an 84.8% attack rate. Image
3) Furthermore, 11 of the 12 cases epidemiologically linked to the theater outbreak were clustered monophyletically within the AY.69 lineage. Image

2) ... where a veterinarian contracted the virus from an infected cat."
"Utilizing 1107 cat serum samples, the results demonstrated a seropositive rate of 22.67%, aligning with trends observed in humans." Image
3) "While distinct patterns were observed among epidemic waves, overall variation was revealed across provinces. Particularly, Samut Sakhon demonstrated a robust positive correlation between the proportion of positive cat sera and human prevalence." Image

KEY STUDY :
Distinct EVOLUTION of SARS-CoV-2 OMICRON XBB and BA.22.86/JN.1 lineages combining INCREASED FITNESS and ANTIBODY EVASION
