Vaccinations of Swine Flu
Posted by admin | Posted in preparation | Posted on 15-07-2009
Vaccine against seasonal influenza strain H1N1 is not believed to protect
us. Vaccines against the Swine Flu to cope with seasonal flu to minimize
infection rates are typically developed, and yet annually it still kills
around half a million of the world’s population. Today, they use an
injection of “killed virus”, the world’s flu vaccines. Manufacturers are
asked to produce a vaccine for H1N1, they are unlikely to be able to
respond quickly enough if a global pandemic is declared.
About a billion doses of any one vaccine each year is the only they can
produce, so that even if all the capacity was switched to fight a pandemic
flu, as opposed to a seasonal flu. Few years ago, the supply of the
vaccines they have produced were enough to epidemic but now is not enough
for the total population’s outbreak.
Deadlier wave of a new H1N1 strain they forecast will reappear this fall
and they have to produce pandemic vaccines as early as now to prepare for a
turn out as the vaccine may not be as effective will be sure to a big waste
of resources with serious results, and there would also be a shortage of
seasonal flu vaccine available. Only a few more weeks were needed for the
World Health Organization (WHO) and Centers for Disease Control and
Prevention) CDC to develop a “seed strain” of the pandemic virus on the
first days May, but producers would then need four to six months before
they could create large volumes of vaccine.
In other point of view, the WHO will attempt to make sure that a
substantial amount is available and should a pandemic be declared and a
vaccine produced, for the benefit of developing countries. Vaccine
manufacturers and countries with standing orders, such as the U.S. and some
European countries will be asked to share with developing countries from
the moment the first batches are ready if an H1N1 vaccine is made.
2009-2010 flu seasons are ineffective against the new strain with the
previous influenza vaccines for the north and south hemispheres. The WHO
claims that two separate immunizations will be required for seasonal and
swine flu, but no decision would be made on whether to begin producing a
swine flu vaccine. The board will receive inputs from manufacturers (e.g.
GlaxoSmithKline, Sanofi-Aventis, Novartis and Baxter International)
regarding when they are able to finish manufacturing the seasonal shot and
begin production of the swine flu vaccine, waiting from the WHO of their
recommendations and “seed virus”, and some may be ready to proceed with
production at that time.
There also antiviral drugs available for treatments of influenza, the virus
is resistant to amantadine and rimantadine but sensitive to the oseltamivir
and zanamivir. There remains concern that this strain may mutate develop
resistance to oseltamivir in the future. For the treatment and prevention
of the Swine Flu, the CDC recommended the use of Tamiflu (oseltamivir) and
Relenza (zanamivir). Studies shows that the medication continues to
maintain its effective that why the U.S. government had already extended
the shelf life of federally stockpiled Tamiflu from their original five
years to seven years.
Buying medications from online sources is not recommended by the WHO
because they believed that half of the drugs they sold are counterfeited.
Others are thinking if they grab up antiviral drugs for their safe even if
they have no symptoms, the health officials warned them may eventually lead
them to the Swine Flu virus developing drug resistance.
