An Innovation In Vaccine Research

By Brown Ezilon.com Articles Published 05/1/2010 | Health

A new discovery on flu vaccines is being experimented by researchers lately, they have come up with a vaccine composed of specially developed antibodies that could actually seek out the infection and neutralise it in the body itself. There would be no longer the need to have repeated yearly vaccines, although research has yet to determine the side effects on humans.

Although these results are promising, other experts remain sceptical, for they affirm that viruses cannot be as vulnerable to the antibodies as demonstrated in the research. They also point out that the enormous dosage of developed antibodies is costly and not easy to inject.

The objective of antibodies, produced by our white blood cells, is to destroy all invading bodies, by tagging them so that they are easily recognizable within our system. Unfortunately the flu viruses mutate continually, this is why we have to have new anti-influenza injections each year.

Researchers have found a way to clamp down the flu viruss neck so that it cannot mutate within the body and cannot therefore transmit further information in order to develop more viruses.

There are 16 types of know flu spikes which can attack our system, the H1 to H 16, the most common being the H5 and this seasons H1. The research work has determined that this new treatment will protect from both these types, they will however need to find specific antibodies for the H3 and B types of influenza, which are other types of frequent influenza breakouts. There is an additional problem, which concerns the duration of antibodies, as their effects within the blood stream usually die out after a few weeks.

Further research needs to be carried out in order to determine the many factors that are still in the way of a definite result.
