The New Rational FDA COVID Vaccine Policy is Long Overdue, Says NanoViricides' Dr. Diwan
SHELTON, CT / ACCESS Newswire / May 22, 2025 / Dr. Anil Diwan, President of NanoViricides, Inc. (NYSE Amer.:NNVC ) (the "Company"), comments on the new COVID Vaccine policy adopted by the US FDA.
The new FDA COVID Vaccine Booster Shots policy [1] is based on the findings that the groups that benefit from repeat of vaccination (i.e. booster shots) are the groups that are likely to be at risk of severe COVID disease from the virus. These groups include all adults over 65 years of age, and persons over 6 months of age that have one or more co-morbidity factors leading to a disposition towards severe COVID if infected.
The FDA policy notes that the benefit of repeat dosing of vaccine among people with low risk (i.e. healthy adults) is uncertain. As such, the FDA now will require randomized, placebo-controlled clinical trials that produce evidence of effectiveness in this healthy adults group if a vaccine is submitted for licensure to include this group.
In the past, the COVID vaccines were approved for all ages above 6 months. This resulted in CDC recommending the COVID vaccines for everyone. Yet, COVID vaccine uptake rate was only about 25% of the eligible persons in the last few years.
Over years of exposure, the population has built immunity due to multiple infections from ever-changing COVID variants as well as multiple vaccinations. An additional booster dose in such population would only make sense if a clear benefit can be proven.
"Evidence-based decision making about vaccine boosters policy for COVID is a welcome change over broadcast vaccine recommendation for all," commented Anil R. Diwan, Ph.D., President and Executive Chairman of NanoViricides, adding, "This rational and scientific, non-dogmatic approach should go a long way towards restoring public trust in institutions that make decisions that affect peoples' lives."
The new policy brings the US FDA policy to be similar to the vaccination policies adopted in most developed countries. Even so, between 100 million to 200 million Americans are estimated to be eligible for boosters because of the broad definition for co-morbidity factors that put a person at high risk of severe COVID, which include obesity, diabetes, asthma, and even mood disorders.
"We believe that when a highly effective antiviral drug against COVID becomes available, the need for vaccination will decrease substantially," said Dr. Diwan, adding, "Our broad-spectrum antiviral drug NV-387 is poised to become an important solution for multiple viral threats that emerge every season, including Influenzas, Coronaviruses, RSV, MPox, and possibly even Measles!"
About NanoViricides
NanoViricides, Inc. (the "Company") ( www.nanoviricides.com ) is a clinical stage company that is creating special purpose nanomaterials for antiviral therapy. The Company's novel nanoviricide™ class of drug candidates and the nanoviricide™ technology are based on intellectual property, technology and proprietary know-how of TheraCour Pharma, Inc. The Company has a Memorandum of Understanding with TheraCour for the development of drugs based on these technologies for all antiviral infections. The MoU does not include cancer and similar diseases that may have viral origin but require different kinds of treatments.
The Company has obtained broad, exclusive, sub-licensable, field licenses to drugs developed in several licensed fields from TheraCour Pharma, Inc. The Company's business model is based on licensing technology from TheraCour Pharma Inc. for specific application verticals of specific viruses, as established at its foundation in 2005.
Our lead drug candidate is NV-387, a broad-spectrum antiviral drug that we plan to develop as a treatment of RSV, COVID, Long COVID, Influenza, and other respiratory viral infections, as well as MPOX/Smallpox infections. Our other advanced drug candidate is NV-HHV-1 for the treatment of Shingles. The Company cannot project an exact date for filing an IND for any of its drugs because of dependence on a number of external collaborators and consultants. The Company is currently focused on advancing NV-387 into Phase II human clinical trials.
NV-CoV-2 (API NV-387) is our nanoviricide drug candidate for COVID-19 that does not encapsulate remdesivir. NV-CoV-2-R is our other drug candidate for COVID-19 that is made up of NV-387 with remdesivir encapsulated within its polymeric micelles. The Company believes that since remdesivir is already US FDA approved, our drug candidate encapsulating remdesivir is likely to be an approvable drug, if safety is comparable. Remdesivir is developed by Gilead. The Company has developed both of its own drug candidates NV-CoV-2 and NV-CoV-2-R independently.
The Company is also developing drugs against a number of viral diseases including oral and genital Herpes, viral diseases of the eye including EKC and herpes keratitis, H1N1 swine flu, H5N1 bird flu, seasonal Influenza, HIV, Hepatitis C, Rabies, Dengue fever, and Ebola virus, among others. NanoViricides' platform technology and programs are based on the TheraCour® nanomedicine technology of TheraCour, which TheraCour licenses from AllExcel. NanoViricides holds a worldwide exclusive perpetual license to this technology for several drugs with specific targeting mechanisms in perpetuity for the treatment of the following human viral diseases: Human Immunodeficiency Virus (HIV/AIDS), Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), Rabies, Herpes Simplex Virus (HSV-1 and HSV-2), Varicella-Zoster Virus (VZV), Influenza and Asian Bird Flu Virus, Dengue viruses, Japanese Encephalitis virus, West Nile Virus, Ebola/Marburg viruses, and certain Coronaviruses. The Company intends to obtain a license for RSV, Poxviruses, and/or Enteroviruses if the initial research is successful. As is customary, the Company must state the risk factor that the path to typical drug development of any pharmaceutical product is extremely lengthy and requires substantial capital. As with any drug development efforts by any company, there can be no assurance at this time that any of the Company's pharmaceutical candidates would show sufficient effectiveness and safety for human clinical development. Further, there can be no assurance at this time that successful results against coronavirus in our lab will lead to successful clinical trials or a successful pharmaceutical product.

How thousands of unreviewed ingredients got into our food — and what FDA can do about it
At least 1,000 ingredients in food products on our grocery store shelves have never been checked for safety by the Food and Drug Administration. Dozens have raised serious safety concerns among experts. How did the FDA allow this? The answer can be found in the agency's lax interpretation of a little-known legal designation that lets companies decide for themselves if ingredients in their products are safe. Fortunately, there are steps the agency can take right now to stem the flow of potentially unsafe ingredients into our food supply. Environmental Defense Fund outlined these steps in a letter we recently sent to the agency, but first let's take a closer look at how we got here. 'Generally Recognized as Safe' is a designation Congress created in 1958 to allow commonly used food ingredients to bypass the FDA's pre-market safety review process. It was meant for food substances — such as oils, vinegar, baking soda and common spices — that were widely considered safe due to their long history of everyday use. Since 1958, this status has been coopted to cover a universe of foods that extends far beyond its original intent. According to FDA regulations, a chemical can receive the designation if experts widely agree that scientific evidence shows its use to be safe. But because 'Generally Recognized as Safe' wasn't meant for newer ingredients, Congress allowed ingredients so designated to skip the FDA's premarket approval process — despite requiring similar evidence for other additives. Under the agency's current interpretation, companies can designate the use of a substance as safe and take products with that substance to market without informing the FDA or the public of its decision. While companies may voluntarily submit a notice to FDA offering safety evidence, they are not required to — and often don't. Our organization estimated that manufacturers have notified FDA of fewer than half of the ingredients they market as safe under the 'Generally Recognized' standard. Companies that do bother to submit a notice to the FDA are free to withdraw it at any point and take their product to market, provided they can cite evidence of its safe use. But this 'evidence' is often far from independent. Companies can, and often do, enlist their own employees or handpicked consultants to conduct their safety assessments. The result is a process riddled with conflicts of interest that lets unsafe foods into Americans' homes. We analyzed 'Generally Recognized as Safe' notices received by the FDA, obtained via a Freedom of Information request, and found that of the 1,163 submitted by companies between 1997 and April 2024, 192 were later withdrawn, with safety concerns cited in at least a dozen cases. We also identified 31 ingredients that companies have advertised to be recognized as safe, such as in press releases, trade publications and on their own websites (see the Appendix of our letter). However, we were unable to find the scientific evidence required under this standard to demonstrate these ingredients are commonly regarded as safe among experts. This raises red flags that FDA should be taking seriously. Although a comprehensive fix to the 'Generally Recognized' standard will require legislation from Congress, there are significant steps the FDA can take right away to ensure a more rigorous determination process that better protects Americans' health. Starting today, the FDA can use existing authority to remove safe designations from ingredients it deems unsafe and take them off the market. It can also notify manufacturers, importers, distributors and retailers that the substance is no longer recognized as safe. In addition, the FDA can enforce the requirement that companies base safety designations on publicly available data. Although this won't curtail companies' ability to self-declare substances as safe, it will require those who do to be transparent in citing their evidence. Third, the FDA can enforce the requirement that safety assessments consider vital health information such as a substance's dietary sources, potential cancer risks and the cumulative health effects of similar substances. Finally, the FDA can make companies revise and resubmit their data for review when they submit 'Generally Recognized as Safe' notices that fail to comply with the criteria. The 'Generally Recognized as Safe' designation is far from a perfect system, but it can work better if it is interpreted and enforced more comprehensively. If the FDA is serious about protecting public health, it should start by fully exercising the tools already at its disposal.

Psychedelics as potential mental health treatment are explored by Trump administration
The Trump administration has expressed interest in exploring psychedelics for their potential in treating PTSD and other debilitating mental health issues, various officials have shared. "The Department shares the goal of ensuring that all Americans — especially our nation's veterans — have access to safe and effective treatments for conditions such as PTSD, addiction and depression," a spokesperson for the U.S. Department of Health and Human Services (HHS), run by Sec. Robert J. Kennedy Jr., said in a statement provided to Fox News Digital. "Secretary Kennedy is committed to applying rigorous, evidence-based science to research efforts aimed at addressing these serious health challenges." Fda Approves First Ai Tool To Predict Breast Cancer Risk In recent years, researchers have been actively investigating the potential of psychedelics, such as MDMA and psilocybin ("magic mushrooms") to treat mental health disorders. MDMA is not approved for clinical use by the U.S. Food and Drug Administration (FDA), but can be studied in clinical settings. Read On The Fox News App Psilocybin is listed as a Schedule I substance under the Controlled Substances Act, which means it has "a high potential for abuse, [is not] currently accepted for medical use in treatment in the United States, and [has] a lack of accepted safety for use under medical supervision." Psilocybin-assisted therapy, however, is legal in Oregon, Colorado and New Mexico. Psychedelic medicines are "showing real promise," according to Dr. Luke Twelves, general practitioner and vice president of medical for Lindus Health in London. Clinical trials have found such treatments safe and effective for patients battling serious mental health issues, according to Twelves. Common Supplements And Medications Could Cause Liver Damage, Studies Show "Take psilocybin, for example — it's demonstrating remarkable results for severe depression that hasn't responded to other medications," he told Fox News Digital. "MDMA is showing similar breakthroughs for PTSD treatment." Clinical trials are also investigating how psychedelics could help with end-of-life anxiety, addiction, eating disorders, chronic pain and OCD, he added. Researchers have faced challenges in terms of regulatory hurdles and proper placebo controls, Twelves said. "Given that these treatments could transform [the] lives of people suffering from conditions where nothing else has worked effectively, it's crucial that we complete this research properly," he said. "The goal is to bring safe, proven psychedelic therapies to the patients who need them most." At President Trump's May 1 cabinet meeting, Department of Veterans Affairs Secretary Doug Collins said that "we're opening up the possibility of psychedelic treatment." Retired Army Sergeant Jonathan Lubecki recently told Fox News' Alexandria Hoff that MDMA stopped his PTSD while he was participating in a clinical trial. "[I] took my first dose of MDMA. I've only taken it three times as part of the clinical trial, haven't taken it since, and haven't found the need to take it since, because I haven't had PTSD," he said. Peter Kasperowicz, Department of Veterans Affairs press secretary, told Fox News Digital the department is safely exploring all avenues that promote the health of veterans. Fallujah Vet Turns Medal Of Heroism Into A Healing Mission For Fellow Warriors With Service Dogs Program "Preliminary findings have produced positive results on psychedelic-assisted therapies for treating mental health conditions," he said. The VA is currently running 11 clinical trials in various phases, with a total of some 800 veterans expected to participate. "The goal of these trials is to determine whether compounds such as MDMA and psilocybin can treat veterans with post-traumatic stress disorder, treatment-resistant depressive disorder, major depressive disorder and potentially other mental health conditions," said Kasperowicz. An MDMA study published in the Jan. 2025 issue of The American Journal of Psychiatry found that the substance is "unlike classical psychedelics." The study noted, "MDMA allows the individual to maintain intact ego functioning and a greater degree of cognitive and perceptual lucidity while still experiencing a prosocial altered state of consciousness that facilitates deeply emotional therapeutic breakthroughs." Click Here To Sign Up For Our Health Newsletter The researchers concluded that MDMA showed "enhanced levels of trust, empathy, self-compassion and a 'window of tolerance'" that traditional psychotherapy lacks. Doug Drysdale, CEO of the Canadian pharmaceutical company Cybin, told Fox News Digital that "the time is now to address the mental health crisis." He said it is "gratifying" that administration officials value the potential benefits of looking into alternative mental health treatments. Cybin is currently in phase 3 of a study of CYB003, a type of psilocybin that has been granted breakthrough therapy designation by the FDA as an additional treatment for major depressive disorder (MDD). "In Cybin's completed Phase 2 MDD study, long-term efficacy results showed that 71% of participants were in remission from depression, and 100% of participants responded to treatment at 12 months after just two 16 mg doses of CYB003," said Drysdale. Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and Fox News' senior medical analyst, previously interviewed two of the country's top researchers on psychedelics — Dr. Rachel Yehuda, founder and director of the Center for Psychedelic Psychotherapy and Trauma Research at Mt. Sinai in New York, and Dr. Charles Marmar, director of the PTSD research program at NYU Langone. "They agree there is therapeutic potential if very carefully studied under very strict medical guidance, but there is a huge downside in terms of unregulated recreational uses," Siegel told Fox News Digital at the time. "Both doctors see likely therapeutic value to psychedelics if carefully managed by medical experts," Siegel added. Ryan Moss, chief science officer at Filament Health, a clinical-stage natural psychedelic drug development company in Canada, emphasized it's important to administer psychedelics in a safe setting when treating mental health conditions. For more Health articles, visit "Psychedelic experiences can sometimes feature anxiety, hallucinations and paranoia," Moss previously told Fox News Digital. "Some patients using traditional psychedelics have reported experiencing adverse cardiovascular events during clinical trials." To mitigate these risks, Moss recommended clinical trial participants receive thorough preparation and monitoring by trained professionals during sessions.
