Scientists have created new strains of polio that is supposed
to protect workers in factories that make the polio vaccine. The new strains
have the same immune reaction but there is little risk of anyone getting polio if the new strain
suddenly escapes. After growing a large amount, vaccine makers “kill” the virus
with formaldehyde and prepare it for syringes. Right now, polio eradication
depends on many volunteers putting drops of the oral Sabin vaccine into
children’s mouth. The Sabin vaccine has
drawbacks; it can mutate back into a dangerous form which can paralyze or kill.
And the vaccine is risky in children
with immune-system problems. Doctors are working with the new vaccine company,
Crucell , to prove that the safer strains grow well in the human cell line.
Although the article provided some evidence that the new
strains for polio for polio will be effective, more evidence should have been
provided to further convince the reader. Also the article discussed how if a
disaster such as an explosion, an earthquake, a tsunami, or a flood, that the
spill could spread like wildfire. I am curious to know what preventative measures
are being taken just in case a disaster of some sort was to happen. True some
things can not be prevented but it seems that no plan of action is in place. If
a spill were to occur it would be a major disaster in of itself. Overall the article was good, it provided
input from doctors and included some evidence that the new strain for polio
will be effective.
