Only a few weeks into the new year, the prospect of getting a successful advanced HIV vaccine shrank after the discontinuation of yet another late-stage trial. On January 18, Janssen, a Johnson & Johnson (J&J) subsidiary, stated that its vaccine was not effective in preventing HIV infections.
The US Food and Drug Administration (FDA) has made changes to the emergency use authorisations (EUAs) of the Pfizer -BioNTech and Moderna bivalent mRNA Covid-19 vaccines. The latest amendment aims to simplify the vaccination schedule for most people. The changes mean that the current bivalent vaccines for the original and Omicron BA.4/BA.5
In the last three years alone, there have been over 633,000 patents filed and granted in the pharmaceutical industry, according to GlobalData’s report on Innovation in Pharmaceuticals: Anti-influenza antibody compositions. However, not all innovations are equal and nor do they follow a constant upward trend.
A third dose of vaccine has been shown to effectively neutralise the Omicron variant of covid-19, according to researchers. Research led by UCLH, UCL and the Francis Crick Institute found that the booster dose successfully stimulates antibody levels that neutralise Omicron. Overall, antibody levels were nearly 2.5
Last year was a positive year for biopharmaceutical companies, particularly those with Covid-19 vaccines. As a result of huge global sales of mRNA Covid-19 vaccines, the split in profits between Pfizer and BioNTech’s Comirnaty contributed towards revenues of $81.3bn and $22.4bn last year, respectively. YoY revenue growth.
Belgium researchers compared the Moderna and Pfizer-BioNTech COVID-19 vaccines and found that the Moderna jabs generated twice the antibodies than the Pfizer-BioNTech vaccine.
Moreover, in low- and middle-income countries, lack of healthcare access increases the disease’s impact, as limited diagnostics, vaccination coverage and medical resources limit early detection and treatment. Monoclonal Antibody Therapies Monoclonal antibodies are gaining traction as targeted treatments for bacterial and viral infections.
QUICK THOUGHT: People believe the COVID-19 vaccine was developed in less than a year but that’s not true. Further scientific research into the virus and recognition that it was not like influenza A, a flu virus known to cause bronchitis, would transpire over the next 30 years. . Funding was not the only issue. Do Lockdowns Work?
RSV researchers at major pharmaceutical companies are currently working to develop new RSV drugs to beat future waves of RSV infection and gain the first RSV vaccine FDA approval. Pharmaceutical companies are pushing to develop drugs and vaccines for RSV with these populations in mind.
While it remains unclear why some people become more gravely ill than others when infected with the SARS-CoV-2 virus that causes COVID-19, researchers have found that an immune deficiency may be part of it. These rogue antibodies blocked interferon action and were not present in patients with mild COVID-19 cases. We said, ‘bingo!’”
Valneva SE, who developed the worlds first FDA-approved chikungunya vaccine , has now unveiled promising Phase III data for its single-shot chikungunya vaccine, IXCHIQ, in adolescents aged 12 to 17. IXCHIQ is the only licensed chikungunya vaccine in the US for adults aged 18 and older at increased risk of exposure to the virus.
Half a million people in the UK with conditions like blood cancer that prevents them being protected from COVID-19 vaccines are facing another winter shielding, because the government has shelved plans to offer treatment with AstraZeneca’s antibody therapy Evusheld. One group of Chinese researchers has reported however that BA.4
Moderna has joined forces with non-profit organisation IAVI on a third phase 1 trial of its candidate HIV vaccine in Africa, where the burden of the virus is still being keenly felt. There are hopes that its mRNA approach, which proved so effective against COVID-19, could succeed where traditional vaccine technologies have failed in HIV.
Novel therapeutics and vaccines for malaria. In September, researchers from Oxford University shared their findings from a Phase IIb study with a more efficacious malaria vaccine called R21, which met the WHO’s 75% efficacy threshold. Apart from vaccines, other approaches for preventing malaria are also being studied.
In advance of public vaccination, a quick and accurate COVID-19 antibody test will help determine the presence of neutralizing antibodies, the molecules that aid in protection against the virus. Credit: UAB BIRMINGHAM, Ala.
The US Food and Drug Administration (FDA) has approved GlaxoSmithKline ’s (GSK) Boostrix (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine adsorbed [Tdap]) for pregnant women during their third trimester to prevent pertussis (whooping cough) in newborn infants.
and worldwide before the introduction of vaccines in the 1940s. Whooping cough, or pertussis, was once a leading cause of death for children in the U.S. In the decades since, the bacterial disease was nearly eradicated in the U.S., with fatalities falling to double digits each year.
Credit: Julianna Han, Ward Lab at Scripps Research LA JOLLA, CA—Scientists at Scripps Research, University of Chicago and Icahn School of Medicine at Mount Sinai have identified a new Achilles’ heel of influenza virus, making progress in the quest for a universal flu vaccine.
A team of scientists from Scripps Research and the University of North Carolina (UNC) has found antibodies in the blood of certain COVID-19 donors that can block infection from a broad set of coronaviruses—specifically, in people who have recovered from the virus and were then vaccinated.
Last week, a study that “stumbled upon” a vaccine for rheumatoid arthritis (RA) was published in the Proceedings of the National Academy of Sciences. The experimental arthritis vaccine was developed by researchers at the University of Toledo (UToledo) and is a major breakthrough for rheumatoid arthritis and other autoimmune diseases as well.
Scientists in the US say they have developed an mRNA-based vaccine that encompasses all 20 known subtypes of influenza that could form the basis of a future universal jab. The goals of the programme are also similar to those in COVID vaccine development.
The new mRNA vaccines have just as good a protective effect against COVID-19 for the very oldest as for younger people. This is evident in a study at Umeå University, where researchers have followed individuals in special housing around Sweden. The research is published in The Lancet Regional Health—Europe.
In this article, Ben Hargreaves looks into the promise of cancer vaccines and how this treatment modality may offer advantages over existing immunotherapies in the oncology sector. One area that is gathering increasing levels of interest is the development of cancer vaccines. A broad front.
In the last three years alone, there have been over 633,000 patents filed and granted in the pharmaceutical industry, according to GlobalData’s report on Innovation in Pharmaceuticals: Monoclonal antibody drugs for cancer. Treatment with monoclonal antibodies also helps immune systems defend against cancer.
This is also why academic research is dominant here, as companies are hesitant to take this on, adds Holger Wille, PhD, associate professor at the Centre for Prions and Protein Folding Diseases at the University of Alberta. Adding to this, the infectivity of prion diseases also makes research challenging, says Wille.
But researchers are testing one therapy that may help: monoclonal antibodies. Many cannot produce enough infection-fighting cells to fend off the coronavirus.
Pfizer/BioNTech’s mRNA vaccine against COVID is a technical marvel – but the ultra-cool temperatures required for storage and stability has been tricky to handle. 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.
Alterations in the biochemical makeup of bulk plasma IgG, or Fc glycosylation, can predict COVID-19 disease severity and vaccineantibody response, according to a recent study by researchers at RUSH University and Northwestern. The results of the study were recently published in Cell Reports.

LA JOLLA, CA—The COVID-causing virus SARS-CoV-2 harbors a vulnerable site at the base of its spike protein that is found also on closely related coronaviruses, according to a new study from Scripps Research.
Early-stage clinical data with CanSino Biologics’ inhaled COVID-19 vaccine show that it was able to stimulate neutralising antibodies against SARS-CoV-2 at a dose well below that required with intramuscular administration.
In the latest episode of the podcast Dominic Tyer speaks with GlaxoSmithKline’s Philip Cruz about the discovery and commercialisation of new vaccines in the light of the pandemic. They also talk about the impact anti-vaxx misinformation has had on vaccine uptake in recent years and what impact COVID has had on that.
The US Food and Drug Administration (FDA) has amended its emergency use authorizations (EUA) for both the Pfizer and Moderna COVID-19 vaccines to incorporate a third dose for immunocompromised individuals. A small study from John Hopkins University has shown that a third dose of a COVID-19 vaccine could indeed help immunocompromised patients.
million people, with no vaccine in sight. However, a new study by researchers at The Wistar Institute, an international biomedical research leader in cancer, immunology, infectious disease, and vaccine development, takes a promising step in the direction of developing […]. PHILADELPHIA — (Feb.
This comparative effectiveness research study compares antibody levels after ChAdOx1 nCoV-19 vaccination in individuals with or without previous SARS-CoV-1 infection.
An intranasal formulation of AstraZeneca’s widely-used COVID-19 vaccine Vaxzevria has failed at the first hurdle, after results from a phase 1 trial found it was unable to stimulate a strong immune response to the virus. Other efforts to develop a nasally-delivered COVID-19 vaccine have met with greater success.
Last year, Belgium’s ExeVir Bio raised 23 million euros ($27 million) to finance development of llama antibodies – and now it is ready to begin clinical development of a potential treatment that could be effective against emerging COVID-19 variants. ExeVir is not the first company to spin out of VIB to focus on camelid antibodies.
