Vaccines Prime The Immune System For A Dangerous Invader

According to the study, this explaining that the vaccines prime the immune system for a dangerous invader by introducing a dead or weakened version of it. That way, if the real threat comes along later, the body is already equipped to recognize it and beat it back. This finally showing that scientists hopeful about a vaccine to prevent HIV.

But the idea behind a universal flu vaccine; is to say we have to get out of the way study are currently doing it. But finding the drugs that could knock back HIV to undetectable levels; and the virus was no longer synonymous with a death sentence. But to truly defeat the virus that causes AIDS, doctors need a vaccine. And after decades of dead ends and dashed hopes; they may finally be on the verge of having one.

Vaccines prime the immune

The human immunodeficiency virus, or HIV, attacks a specific type of white blood cell the body relies on to fight off infections. If left untreated for several years, a patient’s white blood cell count becomes critically low, leading to acquired immunodeficiency syndrome, or AIDS. That making the body vulnerable to bacteria and fungi that can cause tuberculosis, meningitis, certain types of cancer and other serious diseases that can lead to death.

But with classic threats such as measles or polio, the vast majority of people are already able to suppress the virus and eradicate it from their bodies. In those cases, developing a vaccine is as simple as finding a safe way to mimic a natural infection perhaps by introducing a modified version that has been stripping of its weaponry. But HIV is different, because no patient has ever been knowing to overcome the virus on his or her own.

More genetic diversity

HIV is a wily opponent. The virus doesn’t just defend itself against attacking immune cells, it invades them, integrating itself into the victim’s DNA. It can also envelop itself in sugar molecules to keep antibodies from latching onto its shell. Then there are genetic complications. HIV has more genetic diversity than any other known virus. It makes frequent mistakes as it replicates, and it can survive without correcting them.

This ability to rapidly mutate makes it a moving target no match for a vaccine; designed to protect against a single strain. The experimental vaccine, made by Johnson & Johnson; contains an array of genetic sequences from various HIV strains. All of them will be drawn from groups that are at high risk of contracting HIV; including men who have sex with men and transgender people.
