Russia’s SPUTNIK V finds an Indian partner- Dr Reddy’s Laboratory

 

Russian Direct Investment Fund (RDIF), a sovereign wealth fund in Russia has allied Dr Reddy’s Laboratories (DRL), the Hyderabad-based drug manufacturer to cooperate on clinical trials and distribution of Sputnik V vaccine in India. This arrangement claims to deliver the vaccine for general use probably beginning late 2020.

After obtaining regulatory approvals from DCGI (Drug Controller General of India) for conducting trials in India, DRL will receive 100 million doses of the Covid19 vaccine — developed by the Gemaleya National Center of Epidemiology and Microbiology (Moscow, Russia). The results of the early phases (Phase 1 and 2) of trials with the vaccine were recently published in Lancet in September 2020, while both India and Russia were laying the groundwork to pursue further trials and production of the vaccine in India. The Indian Council of Medical Research (ICMR) expresses that Russia has a good track record in development of vaccines.

Sputnik V is based on proven vaccine against adenovirus – the common cold. The vaccine is expected to provide immunity from SARS-CoV-2 (agent responsible for Covid19), for up to two years, according to the Russian health ministry. Findings of phase I/II trial of this vaccine, involving 76 healthy volunteers (aged 18-60 years), which used recombinant adenovirus type 26 and type 5 vector (rAd26-S and rAd5-S), suggests that 85% of participants had detectable antibodies at 14 days after first dose, leaping up to 100% by day 21, after the boosting dose. The findings are published in The Lancet, a renowned peer-reviewed journal in the field of medicine.

Competitors in the field

Meanwhile, AstraZeneca or Oxford vaccine (AZD1222) is also in Phase-3 trials which has partnered India’s Serum Institute to produce it and has secured its position among the leaders in race for public use, even after recent unfortunate pause in its trials due to alleged side effects. DCGI has now revoked its earlier suspension on Oxford Covid-19 vaccine, allowing to continue phase two and three trial and put certain conditions like extra care during screening, close monitoring for adverse events during follow-up.

There are two other Indian vaccines that are being developed and are in Phase I and II stage trials and have shown no significant side-effects yet.

Zydus Cadila is working on ZyCoV-D, has completed phase I and II clinical trials. ZyCoV-D utilises technology based on Plasmid DNA translating into viral protein. Bharat Biotech Limited has developed COVAXIN, in collaboration with the Indian Council of Medical Research (ICMR) – National Institute of Virology (NIV). COVAXIN is an inactivated vaccine with alum as adjuvant.

Globally around 321 vaccine candidates are in development as either confirmed projects in clinical trials or in early-stage "exploratory" or "preclinical" development, as of September 2020. Out of these only seven vaccines are in phase III clinical trial. The WHO also implemented an access to COVID‑19 Tools Accelerator for coordinating global vaccine development, a program called "COVAX" in collaboration with Global Alliance for Vaccines and Immunisation (GAVI) and the Coalition for Epidemic Preparedness Innovations (CEPI). COVAX has the goal to accelerate the development and manufacturing of COVID-19 vaccines, and to assure that access to licensed vaccines is equitably provided to all countries.

Its very comforting to see that multinational companies are doing their utmost to find the answer to this pandemic, but it will be crucial to maintain patient safety. The last thing we need after a pandemic is a global havoc due to adverse events arising from the very cure we are trying to find.

    It's great that the united effort from all stake holders has expedited the entire process of vaccine development not seen previously in the history of human civilization. Hope the vaccine has strong and sustained immune response against the virus with the minimum side effects.

Antibacterial Graphene masks can prevent Corona virus too ?

          Until now face masks have been one of the effective means to decrease the spread of respiratory virus diseases . But the same mask, if improperly used or inappropriately discarded, can negate the insignificant protection offered by the mask. Studies have shown that outside area of the used masks are highly contaminated and it is directly proportional to air quality of the working environment. Majority of bacteria on the mask remain alive even after 8 hours of use. To tackle this problem, a group of researchers from City University of Hong Kong, China demonstrated that by using Laser-Induced Graphene (LIG) in masks, the antibacterial property can be significantly improved. And if combined with photothermal effect (sun light) , the bactericidal property can be increased up to 99.99% within 10 minutes. According to the preliminary report of the study published in ACS Nano, the team of researchers demonstrated the antibacterial activity of LIG usin...

Existing vaccines against new variants of COVID-19: Can they hold the fort?

What is this new variant? A variant is nothing, but a slightly altered or mutated version of a virus. There are thousands of COVID variants present around the world which is to be expected because mutation in viruses is common phenomenon. Most of these mutations are not much of that concern, because they do not provide additional features to the virus. Omicron is strikingly different from many other types due to the long list of genetic mutations it has undergone, which has increased the infectivity of virus. What causes a virus to change to a new variant? When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus obtains to spread, the more it replicates – and the more opportunities it gets to undergo changes. Most viral mutations have little to no impact on the virus’s ability to cause infections and disease. But depending on where the changes are in the virus’s genetic material, they ...

Health supplements- Are they really supplementing you?

  During our childhood, we were told home food is healthy food, then sometime around the 90s came a breakfast revolution. Corn flakes made their way to our tables. This was a ‘new healthy’. Then came green tea. It was followed by quinoa, oat smoothies, kale and seeds. So many of them entered our table like chia, sunflower, pumpkin, flax, sesame and hemp. They planted themselves on our dinner tables and cluttered it and slowly replaced traditional home cooked meals. All of that is acceptable. We were told it is healthy and in 2020, the COVID-19 pandemic showed that healthy alone was marketable enough. Immunity became the new sales pitch. So those milkshakes, ice creams, everything started guaranteeing immunity. You don’t need to be a doctor to identify healthy, you only need to be logical. My logic and experience tell me that we are being tricked in the name of health and wellness. Why don't you open your social media profile and search for health and wellness? You'll find 4.2...
