Australia: Be it polio shots or the Covid-19 vaccine, we need repeated doses to maintain their effectiveness. Now experts have discovered a very basic thing after which a single dose of vaccine can be useful for many years if not decades.
Monash University experts have published research in the journal ‘Immunity’ that could revolutionize the effectiveness and long-term effectiveness of vaccines.
Experts believe that if a subtype of immune cells is targeted, they can be activated and produce long-lasting disease-fighting antibodies.
The same research has shown that especially the large number of cells present in the bone marrow can be made capable of this. After understanding this basic knowledge, we will definitely be able to make a long-lasting vaccine, if not today.
Vaccines enable immune cells in the body to assume infection even when the cells are not germs. In response, they start making antibodies that fight the infection. But even a good vaccine can work for a while.
To find out, experts have tested it on animal models and found success. But the development of a human vaccine is still a long way off.
