A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.
A research group has isolated monoclonal antibodies that, in laboratory and animal studies, prohibited infection by alphaviruses.
Although the development and increasingly widespread availability of effective and safe vaccines provides the greatest hope for the future recovery from the increasingly devastating COVID-19 pandemic, genomic surveillance is emerging as a vital necessity to achieve effective mitigation and containment.
Despite causing a surge in infections this summer that has resulted in thousands of hospitalizations and deaths, the delta variant of the virus that causes COVID-19 is not particularly good at evading the antibodies generated by vaccination, according to a study by researchers at Washington University School of Medicine in St. Louis.
Scientists have discovered that individuals recovering from COVID-19 produce identical clones, or groups, of antibody-producing white blood cells.
Scientists have created an “atlas” that charts how 152 different antibodies attack a major piece of the SARS-CoV-2 machinery, the spike protein.
Researchers created a “nanobody”, a small fragment of a llama antibody, that can evade human cytomegalovirus as it hides away from the immune system.
A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.
Safe and effective vaccines offer hope for an end to the COVID-19 pandemic. However, the possible emergence of vaccine-resistant SARS-CoV-2 variants, as well as novel coronaviruses, make finding treatments that work against all coronaviruses as important as ever.
Researchers from the University of Oxford suggest that adenovirus vaccine vectors may create strong long-term immune system responses.
The capacity of the COVID-19 virus’s spikes to bind to human cells may be hampered by molecules from the same family as the anticoagulant medication heparin.
Immunologists have discovered a molecular route that regulates how crucial immune cells evolve into the immune system’s functioning components.
In our latest interview, AZoLifeSciences spoke to a team of researchers about their latest research which involved carrying out CRISPR/Cas9 in Space.
Researchers have discovered that a majority of the COVID-19 convalescent patients develop and maintain T cell memory for more than 10 months.
Since the start of the COVID-19 epidemic, proteins have been stealthily taking over human lives.
Researchers have identified how mutations on the SARS-CoV-2 spike protein separately create variants that are potentially resistant to antibodies.
Researchers from the University of Southampton have discovered how tumor necrosis factor receptors, a crucial class of immune receptors, are activated.
A new study has discovered a novel tactic used by the bacterium Staphylococcus aureus to resist the immune response, boosting hopes that a vaccine to prevent lethal MRSA infections is closer than previously thought.
A new technique for obtaining pure malaria parasites from infected mosquitos could speed up the development of novel, more powerful malaria vaccinations.
In a recent study, researchers investigated how natural killer cells target breast cancer using the body's own immune system.
COVID-19 continues to claim lives across the world and is infecting millions more. Although several vaccines have recently become available, making significant strides towards preventing COVID-19, what about the treatment of those who already have the infection?
