        <p>One of the major disparities between bacteria and viruses is
the host. A bacteria cell is able to grow on both non-living and living
surfaces, whereas a virus must have a living host, such as animal or
plant. Bacteria cells possess the cell organelles required for their
multiplication as well as growth, they typically reproduce asexually by
the process of binary fusion (McComas, 1998). Viruses contain genetic
material (RNA or DNA) that are packed in a membranous protein coat,
unlike bacteria viruses utilize the host cell during their reproductive
process. A virus makes contact with an individual cell. It inserts RNA or
DNA materials in the host cell, thereby undergoing lytic and lysogenic
phases respectively. These phases lead to the production of numerous
viruses within the host cell, thus killing it (Ahrcanum Word Press,
2009). The outermost cell structure of bacteria encompasses capsule,
peptidoglycan wall, or slime layer, whereas virus outermost makeup has
got viral envelope or a protein coat. Sometime bacteria are very useful
to living organisms, as some bacteria are required in the gut as normal
flora, but viruses are always harmful (McComas, 1998). Diseases caused by
bacteria include pneumonia, and those caused by viruses include swine
flu. The human lung cell has got a cell membrane as its outermost
structure, this membrane act as a protection to the innermost organelles,
such as nucleus, mitochondria, cytoplasm, Golgi apparatus, ribosomes, and
many other organelles. This human lung cell can act as a host cell for
viruses as well as source of food bacteria, such as <em>Staphylococcus
aureus</em> and <em>Streptococcus preumoniae </em>(Ahrcanum Word Press,
2009).</p>
<p>The Pneumovax vaccine is able to reduce the deaths resulting from
swine flu. This is because severe consequences associated with swine flu
virus are as a result of pneumonia. By use Pneumovax vaccine
complications related to pneumonia will be limited in many individual
suffering from swine flu thereby reducing the mortality rate. The vaccine
acts by stimulating the body's capability in neutralizing the bacteria
liable for pneumonia infections. The Preumovax vaccine has the potential
of preventing about 1/3 of pneumonia casualties associated with swine flu
virus (Maugh, 2009). Additionally, influenza or swine flu virus can act
as potential sources of pneumonia in an individual. During the viral
infections, the immune system becomes so weak that organisms like
<em>Staphylococcus aureus</em> and <em>Streptococcus pneumoniae</em> take
that particular chance to invade the lungs, thus causing severe impacts
on an individual. Preumovax vaccine when used is be able to prevent such
opportunistic infections therefore weakening the lethality of swine flu
virus (Maugh, 2009). The vaccine assists in protecting people against
deadly diseases, such as meningitis, using this vaccine is very
significant in preventing infections in the immune compromised
individuals like those suffering from lung disease, liver disease, heart
disease, HIV, spleen dysfunction as well as diabetes. By protecting the
immune compromised individual from bacterial infections, the Pneumovax
vaccine can greatly reduce on the adverse effects of swine flu on such
kind of people (Maugh, 2009).</p>
<p>No, the Pneumovax vaccine will not provide protection to all swine flu
related preumonia cases. This is because, is not so far comprehensible
what percentage, proportion, or fraction of swine flu-related pneumonia
results from <em>Streptococcus preumoniae</em> infectionand thus could be
ameliorated or prevented by vaccination. The preliminary findings
presented from Center for Disease Control indicated that approximately
forty percent of swine flu-related pneumonia contained unknown sources,
and that approximately thirty percent were identified as being caused
through S<em>treptococcus preumoniae</em> infections. This therefore
implies that Preumovax vaccine can only protect 1/3 of the swine flu-
linked pneumonia causalities and not all swine flu-related pneumonia
cases (Maugh, 2009).</p>        <!--INFOLINKS_OFF-->
