Even as several safe and effective COVID-19 vaccines are being administered to people worldwide, scientists are still hard at work developing different vaccine strategies that could provide even stronger or longer-lasting immunity against SARS-CoV-2 and its variants.
COVID-19 vaccine maker Moderna announced this week that results from a study show that the shot is effective against some of the new circulating variants of SARS-CoV-2. In a news release from Moderna, the company reported that the administration of its COVID-19 vaccine induced antibody titers against both variants.
It is important in the process of protein synthesis because mRNA is responsible for transferring genetic information from DNA to ribosomes, which then decodes the genetic information into a protein. In the last few years, researchers have become interested in using in vitro transcribed (IVT) mRNA as a drug delivery agent.
Antibody-like proteins that capture and neutralize SARS-CoV-2 Scientists have used a new high-speed, in vitro selection method to isolate 9 antibody-like proteins (ALPs) that bind to the SARS-CoV-2 virus – 4 of which also exhibited neutralizing activity – within 4 days, according to a new study.
Section 351 of the Public Health Service (PHS) Act defines a biological product as a “virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product, or analogous product. Biologics include a wide range of products , including: Vaccines. Recombinant therapeutic proteins.
The research shows that the activity of the immune messenger type 1 interferon (IFN) protein is diminished, either by genetic mutations or an autoimmune attack by neutralizing antibodies against it, in a subset of COVID-19 patients. Related: Low T Cell Counts Observed in COVID-19 Patients. Mutational Errors in COVID-19 Patients.
The test targets antibodies against the spike protein. This is the focus of vaccines in development and convalescent plasma therapy. The majority of current candidate vaccines aim to induce an antibody response against the spike protein. “As said Thomas Schinecker, CEO Roche Diagnostics.
According to the US biopharma company, genetic analyses of publicly available sequences for the new variants of SARS-CoV-2 suggest the mutations in the viral spike protein that have made them more transmissible shouldn’t affect the way Veklury (remdesivir) works. The UK strain – known as B.1.1.7

Once isolated, molecular clones can be used to generate multiple copies of DNA for the analysis of gene sequences and / or to express proteins obtained for the study or utilization of protein function. These clones can be manipulated and mutated in vitro to alter the expression and function of a protein.
Coding RNAs include messenger RNA (mRNA) and short interfering RNA (siRNA), which encode proteins and silence gene expression, respectively. ASOs are short single-stranded nucleotides that bind to specific messenger RNAs and prevent the production of a particular protein.

JS Bio becomes the exclusive cell culture supplier for Etta Biotech’s transient transfection high titer protein expression platform. JS Bio’s parent company.
“The SARS-CoV-2 vaccines target the spike protein, but this protein is under strong selection pressure and, as we have seen with Omicron, can undergo significant mutations,” said Joyce Jose, assistant professor of biochemistry and molecular biology, Penn State. ” The findings published today (Feb.
Overview of Cell Free Systems Cell-free systems are in-vitro platforms which allow occurrence of biochemical reactions in the absence of living cells. Additionally, these types of cell free systems do not contain proteases and nucleases as crude cell lysates, which further helps in improving the production of many proteins.
With the increased interest and gradual shift of investment from small molecule drugs to biologics and the establishment of several biologics manufacturing companies / biologics CMOs, more than 250 biologic therapies and vaccines have been developed, globally. They are different from small molecules in terms of their size and complexity.
With the expected Emergency Use Authorization (EUA) of Pfizer – BioNTech and Moderna ’s COVID-19 vaccines providing hope that the COVID-19 pandemic will soon be resolved, 2021 is going to need a new primary healthcare campaign. Could it come from the field of neuroscience? which will remain a key shareholder. SciNeuro Pharmaceuticals.

Here’s a look. Urovant Sciences’ Vibegron for Overactive Bladder. The drug is a once-daily, beta-3 adrenergic agonist.
Using its novel yeast display system and large diverse human antibody libraries, AvantGen has identified a panel of high affinity human monoclonal antibody clones that bind to two distinct epitopes on the receptor binding domain of the SARS-CoV-2 spike protein. These findings have been published in Frontiers in Immunology ( [link] ).
The company develops transformative biologics including vaccines and therapeutics for the world’s most debilitating diseases. The company plans to use the capital to expand its pipeline of protein-based vaccines and biologic cancer therapies utilizing its innovative and proprietary Trimer-Tag technology platform.
2 subvariant is steadily increasing in prevalence, specifically in Denmark Use of these tests assess the spread of circulating variants and can help monitor the potential impact of therapeutics, vaccines and public health interventions All Roche SARS-Cov-2 tests correctly identify the virus including these new subvariants. 3 and Delta. “In
Research into mRNA dates back to the 1970s, but with the approval of both Moderna and BioNTech/Pfizer’s vaccines, this approach has finally been validated. At the end of last year, the UK government entered into a partnership with the company, which saw Moderna agree to provide 250 million vaccine doses per year over the course of a decade.
While COVID-19 vaccination efforts have been successful, there is still a significant need for prevention and treatment options for certain populations, including those unable to be vaccinated or those who may have an inadequate response to vaccination.”. The PROVENT trial will give us more clarity in this patient population.
Vaccines are our number one weapon in the fight against infectious diseases, but their development has historically involved a long and complex process taking up to a decade. Before COVID-19, Merck held the record for the fastest modern vaccine ever developed. mRNA’s potential for rapid vaccine delivery.
Johnson & Johnson published interim Phase I/IIa data in the New England Journal of Medicine showing its single-dose COVID-19 vaccine candidate created an immune response that lasted at least 71 days. The data showed that the vaccine induced an immune response and was generally well-tolerated. Here’s a look at last week’s news.
As the US Food and Drug Administration (FDA) handed out an emergency use authorization (EUA) to Janssen’s COVID-19 vaccine over the weekend — making it the third authorized COVID-19 vaccine in the US — many people became laser-focused on the 66 percent average efficacy of the single-dose shot.
People not adequately protected by a COVID-19 vaccine may particularly benefit from pre-exposure prophylaxis with Evusheld. People not adequately protected by a COVID-19 vaccine may particularly benefit from pre-exposure prophylaxis with Evusheld. 2-4 Evusheld was generally well-tolerated in the trial.(2-4).
