Is Covid-19 a biological Weapon?

Covid-19 Infection or Corona Virus is becoming a deadly disease with almost  15.5 million cases worldwide along with 6,34,000 deaths and becoming a matter of great concern. At this point of time people know a lot of things about corona virus but very few know the fact that this deadly virus has been living with humans far before 2019 but with different forms. Let us know what we are talking about.

History of Covid:

Coronaviruses are a big family of different viruses. Some of them cause the common cold in people. Others infect animals, including bats, camels, and cattle..

Scientists first identified a human coronavirus in 1965. It caused a common cold. Later that decade, researchers found a group of similar human and animal viruses and named them after their crown-like appearance.

Seven coronaviruses can infect humans. The one that causes SARS emerged in southern China in 2002 and quickly spread to 28 other countries. More than 8,000 people were infected by July 2003, and 774 died. A small outbreak in 2004 involved only four more cases. 

But the question is how did SARS-CoV-2, the new coronavirus that causes COVID-19 came into being ?

Was this a biological weapon from countries that are engaged in trade war? Some people even cynically claimed that this virus came from aliens living in some other planets....LOL...

 So , I am going to satisfy your thirst to this answer:

SARS-CoV-2 is the newest of seven coronaviruses found in humans, all of which came from animals, either from bats, mice or domestic animals. Bats were also the source of the viruses causing Ebola, rabies, Nipah and Hendra virus infections, Marburg virus disease, and strains of Influenza A virus.

The genetic makeup or “genome” of SARS-CoV-2 has been sequenced and publicly shared thousands of times by scientists all over the world. If the virus had been genetically engineered in a lab there would be signs of manipulation in the genome data. This would include evidence of an existing viral sequence as the backbone for the new virus, and obvious, targeted inserted (or deleted) genetic elements.But no such evidence exists. It is very unlikely that any techniques used to genetically engineer the virus would not leave a genetic signature, like specific identifiable pieces of DNA code.

The genome of SARS-CoV-2 is similar to that of other bat coronaviruses, as well as those of pangolins, all of which have a similar overall genomic architecture. Differences between the genomes of these coronaviruses show natural patterns typical of coronavirus evolution. This suggests that SARS-CoV-2 evolved from a previous wild coronavirus.

Lastly , The most searched question is , When will the vaccine for this deadly virus can be expected to be launched?

Oxford-Astrazeneca's vaccine is undergoing phase III trials: While the vaccine is still undergoing phase III of its trials, preliminary results from the observatory data confirmed that the vaccine elicits a strong immune response in the host bodies and gave encouraging results. AstraZeneca also announced plans to speed up production to meet the promise of delivering a billion doses. However, not everybody's impressed. WHO, in its latest briefing praised the move but said that it still is unrealistic to have a vaccine deployed before early months of 2021.

The Serum Institute of India (SII) said it has started manufacturing a potential coronavirus vaccine developed by the University of Oxford. According to a report, the Pune-based vaccine maker plans to manufacture two-three million doses of vaccine by end-August. Earlier this week, preliminary results of the phase1/2 trial published in the medical journal The Lancet show Oxford COVID-19 vaccine ChAdOx1 nCoV-19 induces strong immune responses with no early safety concerns.The researchers reported that the vaccine triggered a T-cell response within 14 days of vaccination and an antibody response within 28 days. T cells are white blood cells that can attack cells infected with the SARS-CoV-2 virus that causes COVID-19 disease.

The Oxford vaccine candidate against SARS-CoV-2 virus is backed by British biopharmaceutical company AstraZeneca, which has signed an agreement with SII for 1 billion doses of the vaccine. Under the deal, SII will extensively manufacture the Oxford vaccine for India and Gavi countries.

Therefore we should keep our hopes high and with the optimistic attitude we need to wait for a positive NEWS in days to come. Till then , Stay Healthy and Follow all the W.H.O. guidelines.
