Scientists now use cutting-edge techniques, including biological therapies that target specific immune system components and precision medicine approaches that personalize treatment plans based on a patient’s genetic profile.
Researchers at the University of Southampton have gained unprecedented new insight into the key properties of an antibody needed to fight off cancer. The interdisciplinary study, published in Science Immunology, revealed how changing the flexibility of the antibody could stimulate a stronger immuneresponse.

A nasal delivery method will also produce an immuneresponse at the point where the virus enters the body. The company announced a phase 1 trial is beginning of its nasal spray vaccine just as scientists in the UK said they are considering a similar approach.
In order to make the best use of scarce vaccine resources the UK has opted to extend the time between doses to up to 12 weeks, a strategy that has been criticised by some scientists who are fearful that it could cause vaccine-tolerant strains of the virus to emerge.
Better activation of innate and adaptive immuneresponses was achieved with CV2CoV, resulting in faster response onset, higher titers of antibodies, and stronger memory B and T cell activation as compared to the first-generation candidate, CVnCoV.

It codes for an antigen called eOD-GT8 60mer and, in the study, stimulated a targeted B-cell immuneresponse in 97% of vaccine recipients. One candidate – mRNA-1644 – has already shown its potential in an earlier phase 1 trial (IAVI G001) run in the US. HVAD #HVAD2022 pic.twitter.com/KLrVRXtEAv.
Just a few months after starting clinical trials of its nasal spray vaccine for COVID-19, US biotech Altimmune is abandoning the project, saying that it generated weaker than expected immuneresponses in a phase 1 trial. . We believe that prior immunity in humans may be important for a robust immuneresponse to intranasal dosing.”
The test has been designed to quantitatively measure of immunoglobulin G (IgG) antibodies to aid clinicians in identifying patients with an immune Covid-19 response pre- and post-vaccination. As we follow individuals over the course of a year, we are repeatedly testing them for both virus and antibodies.”.
More than three decades ago, scientists at the National Cancer Institute began exploring ways to fight cancer using the patient’s immune system. The global immunotherapy market, which includes CAR T-cell therapy, adoptive cell therapies, checkpoint inhibitors, monoclonal antibodies, and other immunotherapies, is expected to grow by 10.1%

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.
Once inside the cell, the DNA plasmids instruct the cell to produce the targeted antigen, triggering an immuneresponse against the antigen. So far however Inovio has reported relatively sparse data with its vaccine, with limited results from a phase 1 human trial in June and following that with non-human primate data in July.

Early clinical results are consistent with preclinical studies and suggest THOR-707 (SAR444245) may promote an anti-tumor immuneresponse without alpha-mediated side effects, both alone and in combination with anti-PD-1. Editor’s Note : Sanofi previously entered into an agreement with Merck & Co. Source link:[link].
Moderna’s COVID-19 vaccine triggers an immuneresponse in older adults. As observed in 45 younger adults, the middle dose of the vaccine triggered the production of neutralizing antibodies against SARS-CoV-2, the virus, which causes COVID-19 , in 10 patients aged 56 to 70 and 10 patients over 71.
Verily collaborates with Janssen to launch COVID-19 immuneresponse study. Verily is partnering with Johnson & Johnson’s Janssen division to witness the body’s earliest immuneresponses to a coronavirus infection, with people participating in the research from within their homes. .
An expert review by a world group of scientists, including some at the WHO and FDA, concludes that, even for the delta variant, vaccine efficacy against severe COVID is so high that booster doses for the overall population aren’t appropriate at this stage within the pandemic. Considerations in boosting COVID-19 vaccine immuneresponses.
Northwestern Medicine scientists have shown for the first time that coronavirus vaccines and prior coronavirus infections can provide broad immunity against other, similar coronaviruses. “A reason we don’t have an effective HIV vaccine is because it’s hard to develop cross-reactive antibodies,” Penaloza-MacMaster said.
As research developments into RNA vaccines 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.
On top of this, another 8 million carry auto-antibodies, blood molecules that indicate a person’s chance of developing an autoimmune disease.
