Vaccine is claimed to
be a miraculous gift from the medical field to humanity. Vaccine is made by
using an attenuated strain of the virus or a less harmful virus than the definite
one and introduce it to human body. Body generates an immune response as soon
as it recognises a foreign object entering the body. The immune response
created once, always stays as a memory in immune system, hence the next time if
the same foreign body (immunologically known as an antigen) is identified entered,
it is eliminated out immediately.
Our very well-known
COVID-19 or Corona Virus or SARS-CoV 2 virus, has created a havoc in the whole
world. A vaccination for COVID-19 or Corona Virus or SARS-CoV 2 virus, is the
need of the hour. Fortuitously, this year Vaccine making process has spanned a
huge difference of 15-20 years of vaccine creation to about 1 year of research
for development of vaccine against the Corona Virus. There are many countries
that are under Phase three of Clinical Trials, although this vaccine is created
from the proteins that are present on the Corona Virus which will ideally act
as the antigen to create an immune response. This vaccine into the trials, but
has some underlying effects on the human body, also this vaccine needs to be stored
at -70 Degree Celsius & some of them require 2 doses of vaccine to be taken
to generate complete immunity.
Overcoming all these
factors, scientists claim that the RegaVax 2021, is going to be an extraordinary
vaccine for present COVID 19 Pandemic. The new vaccine is yet in animal trails.
This vaccine uses the Yellow fever causing virus as the vector, this will
provide vaccination against the Yellow fever. This will also be a delightful
news for the WHO’s Campaign to eradicate Yellow Fever Until 2026. The strain “YF17D”
is being used now for a long time in the vaccination for Yellow Fever disease. Considering
this is, it already offers a relief that it will not be a harmful strain to be
used as a vaccination. It will be the World’s First Double Target Vaccine. To
create this vaccine friendly strain, they genetically engineered a small virulence
genetic information from the Corona Virus and inserted it into the “YF17D”.
The genetically modified organism expresses the identical spike proteins as the
Corona Virus. When these cells infect the human cells, it generates the same
immune response, but supresses the infection as the virus isn’t COVID-19 or
Corona Virus or SARS-CoV 2 virus.
The vaccine when
tested on hamsters it did not produce any Lung infection but the ones that received
another Vaccine showed clear signs of Lung Disease. The vaccination of Monkeys displayed
an immune response and clearance of all antigens within 7 days of active vaccination.
This result is quite encouraging while compared to other vaccines. Once the
human Clinical trials are carried out, this vaccine may be the most preferred
vaccine against COVID-19 or Corona Virus or SARS-CoV 2 virus.
