An HIVA vaccine candidate is showing positive results so far, which prompts a crucial component in the human immune response for 97 per cent of vaccine recipients.
A small phase 1 trial was conducted to test a vaccine made from an engineered protein found on HIV. Viral. This particle was designed for the body to be able to generate broad neutralizing radiation. antibodiesThese are believed to be crucial in creating HIV immunity.
Broadly neutralizing antibody would recognize large amounts of HIV subtypes. This is important to provide immunity as the HIV virus evolves frequently.
38 participants received either the vaccine candidate, or a placebo. 35 of the 36 who were given the vaccine candidate activated broadly neutralizing antibodies. AntibodyPrecursor B cells could be the first step in the path to immunity.
According to William Schief (one of the authors), the goal of this technique is to train the immune system in recognition of a variety of HIV subtypes naturally occurring. Schief is an associate professor at Scripps Research’s department of microbiology and immunology.
“There are very few areas on the HIV spike surface that are the same or nearly the same between isolates. Schief stated that we are trying to get very specific antibodies that can bind to these patches.
No one experienced any serious side effects in the phase 1 study. Other side effects such as pain at the injection site and headaches were mild to moderate and resolved within one to two days.
These are the results Published in an academic journal Science On December 1, 2022, it was World AIDSDay, where First announced in 2021At the virtual conference hosted the International AIDS Society HIV Research for Prevention. Scripps Research and International AIDS Vaccine Initiative jointly ran the trial.
Since almost 40 years ago, scientists have been trying to develop an HIV vaccine.
HIV vaccination is notoriously difficult. HIV’s infected people are a major reason for this. Tendency to Mutate. It can be able to avoid the immune system by rapidly changing and evolving, making it harder to identify.
Moreover, almost no one is left behind. A few Cases with high profile appealHe has now been free from HIV infection. This means that we don’t know how immune cells can protect us from infection.
This vaccine is the first in a series that will use different HIV particles to train the immune system. As shots progress, molecules are closer to HIV-like particles. Viral infectionsHowever, antibodies can be produced until they are able to bind to multiple types of HIV.
Schief stated, “It’s a new way to think about how to make vaccines.”
Moderna is working on an HIV vaccine, based upon similar research.
Schief says that his team works with Moderna, the biotech giant. Develop and test a vaccineInstead of using a protein-based model, the immune-training HIV particles will be delivered via mRNA. A phase 1 study currently tests the same particle as well as another engineered particle with an mRNA delivery method. A second study is testing the exact same particle in a Clinical trialAfrica.
Schief said that it would take some time before phase 2 trials could begin. He also stated that there is no guarantee that this vaccine will ever work.
He said that if this happens, the technique could be used for other vaccines such as a universal vaccine. coronavirusFlu vaccine.
“We believe that there are some possibilities that this approach may help for more than HIV,” Schief said, “even if HIV is the only benefit.”
