In a new development, a recent paper published in Biology Methods & Protocols by Oxford University Press has highlighted a promising avenue for enhancing vaccine efficacy against infectious pathogens like the COVID-19 virus. The implications of this finding are far-reaching, as it holds the potential to revolutionize vaccine design.
Vaccines have consistently demonstrated their efficacy in protecting people from infectious diseases. Yet, the recent COVID-19 pandemic highlighted the obstacles that are inherent today in the development of vaccines. Stabilizers play a crucial role in maintaining the vaccine's potency and integrity throughout its shelf life.
Even after microbiologists discovered the bacterium that causes the illness in 1882, it wasn’t until the 1920s that researchers were able to develop a vaccine for TB. These breakthroughs have significantly curbed cases, with vaccination reducing the odds of death by 74 percent. tuberculosis , to develop the vaccine.
The COVID-19 pandemic brought mRNA to global prominence by developing highly effective vaccines by Moderna and Pfizer-BioNTech. However, mRNA technology has introduced new possibilities, particularly in developing personalized cancer vaccines and combination therapies.
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.
Phase 3 study met primary and secondary endpoints demonstrating MenQuadfi ® induced superior immuneresponses to serogroup C compared to a standard-of-care vaccine in healthy toddlers MenQuadfi is the first and only quadrivalent ACWY vaccine to demonstrate superior immuneresponse against serogroup C in toddlers.
These newly formed mutated proteins are called neoantigens and they are only present on tumour cells and are not found in normal, healthy cells. These neoantigens are identified by T cells of the immune system as foreign proteins and thus trigger an immuneresponse.
In this study , we demonstrated that AMP immunotherapy can boost TCR-T cell therapy by acting directly in the lymph nodes to promote the coordination of tumour-specific T cell responses by antigen presenting cells. This combination approach resulted in durable anti-tumour T cell responses and tumour eradication.
Immunopeptidomics is a rapidly expanding field at the intersection of immunology and proteomics that focuses on the identification and characterization of peptides presented by major histocompatibility complex (MHC) molecules, also known as the human leukocyte antigen (HLA), on cell surfaces.
While lockdowns may slow the rate of viral transmission in the short term, our longer time battle with the virus will depend on how quickly the population develops sufficient immunity (whether through natural exposure or a vaccine, once one becomes available). Selecting an appropriate antigen mix, however, is probably the easier part.
A sub-analysis from the Oxford-led COV001 and COV002 trials with Vaxzevria induced strong immuneresponses following either a prolonged second dose interval of up to 45 weeks or following a third boosting dose. There is an excellent response to a second dose, even after a 10 month delay from the first.”.
Leishmania infection may arise from virulence factors; they are treatable with medications or vaccinations more promptly and might greatly shorten the duration of treatment.

25, 2021 — Giving melanoma patients a “personalized” vaccine can prompt an anti-tumor immuneresponse that lasts for years, an early study finds. But it builds on earlier work showing it is possible to spur the immune system to respond to an individual’s unique tumor. MONDAY, Jan.
8, 2020 — AstraZeneca’s COVID-19 vaccine is safe and effective, new data from late-stage trials shows. Overall, the vaccine protected against symptomatic disease in 70% of cases, according to a team led by researchers from Oxford University in England. TUESDAY, Dec. 8 in The Lancet.
Biogen today announced results of a new analysis of immuneresponse to the COVID-19 vaccine among people with multiple sclerosis (MS). Germany and Spain, researchers evaluated blood samples from 322 participants 28-90 days after their last COVID-19 vaccine dose. Using data from the MS PATHS network in the U.S.,

In the unprecedented context of at least 13 variants circulating within the study population subset assessed at this interim analysis, CVnCoV demonstrated an interim vaccine efficacy of 47% against COVID-19 disease of any severity and did not meet prespecified statistical success criteria. About CVnCoV.
Food and Drug Administration (FDA) advisory panel in regard to the COVID-19 vaccine from Moderna. The Vaccines and Related Biological Products Advisory Committee will be determining whether the product should be authorized for emergency use, according to CNBC. ET, according to a draft of the agenda.
The vaccine candidate demonstrated non-inferiority in primary endpoints for five Neisseria meningitidis serogroups (A, B, C, W, and Y) compared to two doses of Bexsero (meningococcal group B vaccine) and one dose of Menveo (meningococcal group A, C, W-135, and Y conjugate vaccine) in 10–25-year-olds.
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.
An important limitation of antibodies against tumour antigens is that these agents direct responses to molecular targets present on the surface of the cell. Figure 1: HLA Class I presentation of peptides derived from intracellular antigens. However, most of these peptides may also be presented by normal cells.

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.
If a virus is disease-causing, the right mutation can allow the virus to escape the immuneresponse by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes. These epitopes could then be used in a vaccine to train T cells, providing protective immunity.
Food and Drug Administration said Monday that any American who gets the Moderna or Pfizer coronavirus vaccines must get two full doses, despite international debate on possible ways to stretch vaccine supply. vaccine effort just as the public is starting to trust the program, Dr. Anthony Fauci told The New York Times.
But there is a catch: 99 percent of the study’s participants didn’t make enough neutralizing antibodies to mount an ideal immuneresponse. Three neutralized the virus even when present at extremely low levels, and they now will be studied further as possible monoclonal antibodies. But again, not all antibodies are created equal.
European Medicines Agency to Conduct First-Ever Parallel Assessment of a Medicinal Product, Takeda’s Dengue Vaccine Candidate (TAK-003), for use in the EU; Countries Outside of the EU through the EU-M4all (Previously Article 58) Procedure.
More recently, researchers have begun to look at conjugating immunomodulatory agents to antibodies to directly activate an immuneresponse against the tumour. This approach – immune-stimulating antibody conjugates (ISACs) – uses a payload that stimulates the innate and adaptive immuneresponses, recruiting tumour-fighting T cells.
The FDA decision is informed by the results of the Phase 2b proof-of-concept study of RSVpreF (NCT04032093), a global, double-blinded, placebo-controlled study that assessed the safety and immunogenicity of RSVpreF in healthy pregnant women ages 18 through 49 years old, who were vaccinated between 28- and 36-weeks gestation, and their infants.
Additionally, in evaluating the effectiveness of our initial pipeline asset, we sought tumours suitable for intratumoural injection that present surface-accessible lesions. The preclinical results demonstrated significant immuneresponses and tumour regression. Activation of the ELANE pathway appears pivotal.
Also, last week’s digest had an error: The country that approved the malaria vaccine was Ghana. Vaccines (basically little fat bubbles filled with mRNA and some dissolvable polymers) were physically printed onto microneedle patches using a robot. The patches have little spikes that help push the vaccines through the skin.
