In Dire Need of Swine Flu Vaccine
Sulumits Retsambew : According to the World Health Organization, efforts to develop a vaccine against swine influenza has been underway since the first human case of virus was confirmed. Preliminary estimates of the dose of the vaccine is administered within 5 to 6 months.
Although people diagnosed with the H1N1 virus appears to be in charge of recovery, there were dead. In addition, receipt of vaccines for this virus is particularly important in the elderly and people with weakened immune systems because they are prone to complications such as pneumonia.
Also, the vaccine will provide protection if the problem persists, especially during the winter months, which is when the flu is in full swing.
According to the World Health Organization (WHO), but still incomplete, the data show that the vaccine against seasonal influenza will provide little or no protection against influenza virus. Each year a new batch of vaccine against influenza is developed, and what are the tensions that WHO determines what is most likely circulate in the winter months, which is the peak season for influenza epidemics.
The flu virus is present in several strains of different proteins on the surface. The body’s immune system can fight and destroy a virus if you are able to recognize these proteins. Note that the antibodies recognize a strain that can not detect other strains.
Existing vaccines can provide some protection against swine flu, if the proteins on their surface are similar to strains used to produce the vaccine before. According NIBSC, trying to determine if the virus of swine influenza A H1N1 strain of influenza type A, as well as vaccines against current H1N1 vaccines.
The preparation of a vaccine after a virus, because they provide the basis for the production of the vaccine. As such, there is always a time delay, while the vaccine is being developed. Preparation of a vaccine involves several steps that will take several months before a vaccine is available.
According to WHO estimates, the virus needs to produce the vaccine is made available to vaccine manufacturers in mid-May, while the dose of a new vaccine could be ready within 5 to 6 months after. The waiting time would be much more if the growth of vaccine quickly.
Vaccination plays a crucial role in preventing and reducing the impact of severe conditions. Unfortunately, they are not totally effective and can lose their effectiveness if the virus mutates.
Current vaccines against influenza are valid for one year and 70% – 80% effective against the transmission of strains of influenza viruses that are identical to strains used in vaccine production.
WHO estimates that it is too early to know how the A (H1N1) virus of change. It is followed closely the changes in the virus, which will help countries to respond quickly to major changes that the virus can show.
Vaccines help the body fight against disease, where a person is afflicted with the disease in the future. In addition, an antiviral drug used in people already infected with a virus. Although the work of different ways, usually working to prevent the spread of virus to different cells of the body.
Swine influenza vaccines are administered before exposure to a virus which would be protected by the agent. Antiviral drugs work only if administered within a certain period of time before or after being exposed to the virus.
