These 6 vaccines are helping covid-19| no 3 is master
From December 2019 till
now the world is facing a deadly virus, coronavirus which is originally from China and spread around the
world. Now world’s leading country is still working hard to find out a vaccine against this deadly covid-19.
Many results
out and become outdated. Now some more trials are in the process which has created new hopes for humanity. Nations around the world have closed their
borders and ordered a strict lockdown in order to avoid further pressure on the
already overwhelmed medical care system.
With more than 4.1 million cases
globally and close to 283876 fatalities, the COVID-19 graph continues to rise.
At the same time, scientists and researchers across the
globe are racing against the time to develop a vaccine for the novel
coronavirus. As of now, almost 100 research groups are working round the clock
to develop a potential vaccine for COVID-19.
How long does it take to develop a vaccine?
It is important to note that a vaccine fit for humans
usually takes years to develop as it goes through a series of human trials to
test its safety and efficiency.
The World Health Organization is tracking the
potential vaccines for COVID-19 in the clinical evaluation Here’s taking a look
at the four potential vaccines which are leading the race.
The Oxford University
The University of Oxford has developed a vaccine candidate
‘ChAdOx1 to-19 in under three months.
The vaccine candidate uses a weakened the strain of common cold virus (Adenovirus) and is combined with the genetic
material of the SARS-COV-2 (the coronavirus causing COVID-19)
This will enable the body to identify the spike protein of
the novel coronavirus. The vaccine candidate is now in a clinical trial phase-1
and healthy volunteers have already been injected to check its safety and
efficiency.
Massachusetts-based Moderna vaccine
In the US. the Massachusetts-based biotech company Modera is
developing an RNA-based vaccine in collaboration with the National Institute of
Allergy and Infectious Diseases (NIAID).
The vaccine candidate mRNA-1273 has
already conducted phase 1 trials and is all set to begin phase 2 trials.
The
RNA vaccine works by entering the human cells and carrying the molecular
instructions to make the viral protein.
Once, this viral protein is recognized
by the body, the immune systems of the body are triggered.
Beijing-based Sinovac Biotech
Chinese scientists are claiming to have successfully tested
a potential vaccine for the novel coronavirus in monkeys.
To conduct this
experiment, the researchers injected the monkeys with the potential vaccine
PicoVacc which is made by Sinovac Biotech, a Chinese biopharmaceutical company.
The monkeys were later exposed to a novel coronavirus and it was found that those
injected with a dose of the potential vaccine were largely protected from the
virus. The vaccine is currently undergoing human clinical trials.
Pfizer and BioNTech vaccine
US-based Pfizer pharmaceutical company and its German
partner BioNteh are working together on four RNA vaccine candidates. They also
began clinical trials of their vaccine candidate BNT162.
Their vaccine
candidate is based on specially designed messenger RNA (similar to the Moderna
vaccine) and the trials for testing the vaccine are taking place in the USA they plan to test the potential vaccine on 360 healthy volunteers.
What is the status of the COVID-19 vaccine in India?
As per recent reports, the Indian Council of Medical
Research ( ICMR( has teamed up with Bharat Biotech International Limited (BBIL)
for developing the COVID-19 vaccine.
It is important to note that the vaccine will
use the virus strain isolated at the National Institute of Virology (NIV), in
Pune. The strain has been successfully transferred from NIB to BBIL.
Moreover,
the Serum Institute of India (SII), which is the world’s largest maker of
vaccines by volume has partnered with Oxford University to produce up to 60
million doses of a potential vaccine.
DNA BASED VACCINE BY Inovio Pharmaceuticals
Inovio Pharmaceuticals, a biotechnology company received 5
million dollars in aid for developing a vaccine for the novel coronavirus.
Located
in Plymouth Meeting, Pennsylvania, the pharmaceuticals have developed a potential vaccine in its San Diego lab and are all set to begin Phase!
In the trial at The University of Pennsylvania, the vaccine is named INO-4800 and each volunteer
will receive two doses of the relatively novel DNA-based vaccine candidate,
four weeks apart to check its efficiency and safety.
The Bcg vaccine
I think that most of
us know briefly about the BCG vaccine this is not any new invention for covid-19 but it is the old vaccine.
But the important
thing here is that doctors and researchers find hope that it will help to treat
this deadly virus.
The full name of this vaccine is The Bacillus
Calmette-Guerin (BCG) live-attenuated vaccine candidate is in phase 2/3 and
is used against tuberculosis to boost the immune system.
Clinical trials are
being conducted to test the effectiveness and safety of this vaccine candidate in
protecting people against COVID-19.
Final words …
Now, these new trials have created some more hope for us but
time will prove what vaccine will vanish this deadly virus. Life is
running inside the four-door and hopes are waiting for the new vaccines.
Here I want
to say as per who has guided us and the rest of the world you should work on your immunity to strangers who can beat easily the covid
-19 virus.
And there are lots of food and herbs which have the superpower to boost
your immune system do you know how your immune system reacts when your body
finds a virus attack.
And one more important thing is that there are two types of
immunity systems active immunity and passive immunity you must find out related information to build up your immunity.
