Avian Influenza (Bird Flu) works well with DNA vaccinations
No Comments »
Studies show when treating patients with H5N1 avian influenza, if DNA vaccines were first used to build the H5N1 protein, the results would be successful, say doctors. A recent report stated clinical studies have been conducted to prove the same by National Institute of Allergy and Infectious Diseases (NIAID).
In this report it was clearly stated that most who volunteered for the research, were patients who were given the DNA vaccine. This vaccine was given to them prior to the booster being given, some twenty four weeks ahead of the booster, says a source. The vaccine was made from an inactivated avian influenza virus which was able to manufacture antibodies on great amounts and which were mean to help protect the patient from a certain protein which acts as a team leader, which is HEMAGGLUTININ or HA, says a source.
Most of the avian influenza vaccines available are made to extract antibodies towards HA, says a source. However, every year there is a change and hence vaccines would have to be repeated on a yearly basis so that immunity can be maintained, say doctors and specialists with avian influenza. Some patients who volunteered showed that the antibodies were neutralized at the stem of HA, which is a region that is a warehouse for the influenza, as described by specialists.
By doing such studies on volunteers with avian influenza, it was proved that when the antibodies are neutralized, the possibility to extract antibodies that aid avian influenza through vaccination is successful, says a source. Such experiments and findings are milestones in research and very significant as well. These studies would thus be termed as the pathway to learning how one can not only save them from avian influenza, but from other virus attacks as well, says a source.
Studies also show that one can now elicit the antibodies from the HA steam in humans as well. most research scientists are hoping that they would be able to bring out to the world new rays of hope where before the avian influenza vaccine is administered, DNA vaccine is given to extract high protein anti bodies within the patients body system.
It is important for the world to have a vaccine which is effective and can work to eradicate avian influenza; however, it has been proven difficult to bring out inactivated viruses. Inactivated viruses aren't apt, since they do not allow protective antibodies on a high level to form within the patient's body, beating the purpose of curing the patient on a while. Studies have shown that when patients receive two doses of the inactivated avian influenza virus vaccine and wait for twenty four weeks, they have very low amounts of protective antibodies forming with them.
Only a handful could generate antibodies which were protective and on a large amount to prevent them from further attacks of active avian influenza viruses, says a source. Research is still on to know if the DNA vaccine can thus help combat the avian influenza or not, till then we shall wait for further news.
