Thirty years ago, Katalin Karikó had what was then an outlandish idea: use messenger RNA as a medicine. One rejection she might now be able to laugh about was a research opportunity with funding for six scientists. But getting funding to demonstrate that might be possible was impossible, despite three decades of trying.

After being hailed as a triumph of public-private drug development, Moderna’s partnership with the US government on its COVID-19 vaccine looks like it may descend into acrimony. The patent has been filed but not yet awarded.
The answer may lie in the genetic code of the virus, which scientists at Duke University have found contains several silent mutations that affect protein folding. Moreover, Berrio says the changes likely affected the folding and function of viral RNA. These mutations may thus be “silent” as they do not alter protein structure.
The 2024 Nobel Prize in Physiology or Medicine has been awarded to American scientists Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA (or miRNA) and its role in post-transcriptional gene regulation. Their ability to modulate gene expression at the RNA level provides a novel therapeutic approach for conditions.

But the tragic events of 2020 have meant these companies have become household names as their trailblazing mRNA vaccines became the first to be approved by regulators against the COVID-19 scourge.
So far, neither variant seems to be associated with more severe COVID-19 symptoms, although there has been some preliminary research suggesting the SA strain could allow reinfection with SARS-CoV-2, and also be less susceptible to vaccines.
Messenger RNA (mRNA) vaccines to prevent COVID-19 have made headlines around the world recently, but scientists have also been working on mRNA vaccines to treat or prevent other diseases, including some forms of cancer.

Just one mutation can lead to a complete change in protein formation.
As research developments into RNAvaccines help scientists accelerate drug candidates to arm the immune system against coronavirus, Pharma IQ ’s Keeping tabs on Covid-19 update returns with news from some of the biotechnology innovators leading the fight against the global pandemic.
The UK has agreed a 50 million-dose order for a COVID-19 vaccine with German biotech CureVac to support development of a shot that specifically targets emerging variants of the virus. AZ has said it is confident however that it could quickly update its vaccine and have a new version ready for the autumn.
22, 2021 — Everyone has heard the scary reports about the new, more infectious coronavirus variants that are circulating in countries around the world, but scientists aren’t pushing the panic button at this point. Because the new COVID-19 vaccines should still work on these viral interlopers. FRIDAY, Jan.
The study assessed cynomolgus macaques vaccinated with 12µg of either the first or second-generation vaccine candidate. During challenge with the original SARS-CoV-2 virus, animals vaccinated with CV2CoV were found to be better protected based on highly effective clearance of the virus in the lungs and nasal passages.

An important feature of the test that contributes to its reduced cost is the fact that sample processing does not require a separate nucleic acid (RNA) extraction step. This is significant because shortages of RNA extraction kits have been a recurrent issue since the beginning of the pandemic.
This approach is facilitated by developing ASOs and RNA interference (RNAi) therapies, which target the various molecular and genetic mechanisms contributing to ALS pathophysiology and disease progression. However, work is needed before CRISPR-mediated treatments become possible, including a better understanding of the genes involved in ALS.
Vaccinations in the past have always been either weak or inactive forms of a pathogen which was given to the body so that our immune system is trained to recognize that given pathogen. There are several advantages to approaching vaccination this way. This alone makes them much safer than most conventional vaccines on the market today.
