COVID-19: Vaccine Is The Only Hope

 

Vaccine

Vaccines produce antibodies in the subject. Vaccines make the immune system of body capable of fighting the virus which causes infection.

COVID-19 is a threat for the world. All precautionary measures are helping very little in controlling the spread of the virus. Most of the countries have imposed lockdown restrictions.

The total number of COVID-19 cases has surpassed 6.5 million. We are failing to control the spread. Our only hope is the development of a vaccine. Scientists all across the world are trying to develop a vaccine.

At present there are 10 candidate vaccines. Following are some of the vaccine developers:

  • University of Oxford/AstraZeneca
  • CanSino Biological Inc./Beijing Institute of Biotechnology
  • Wuhan Institute of Biological Products/Sinopharm
  • Beijing Institute of Biological Products/Sinopharm

There are 6 other candidates. All of these are trying their best to develop vaccine as fast as possible and effective.

Every other day, a vaccine candidate promises in animal testing or one which can be tested on human beings. All of us are hopeful that scientists and researchers will be able to make a vaccine and will give us a breakthrough from the disease which has ruined our economies and communities.

Time Required

Health experts such as Dr Anthony Fauci said earlier that development of a vaccine will take 12 to 18 months. It is quite obvious because research, development and supply collectively need that much time.

The vaccines, in testing phases, are being  tested on animals only. The vaccines are not currently in use for humans except when there’s no hope left. But now, scientists are hopeful that a safe vaccine will be ready to be tested on humans by the end of this year safely.

The Director of National Institute of Health (NIH), Dr Francis Collins says that at least 1 safe vaccine will be made by the end of 2020.

Testing:

Initially, the vaccines will be tested on people at the highest risk, specially health care workers and people with long term care facilities. Volunteers will also be tested, if any.

Distribution:

If the vaccine proves to be useful, the aim would be to start producing it at large scale. In the first or second quarter of 2021, there would be more than 100 million doses, but it would not be enough for everybody. According to WHO’s Chief Scientist, it will take 4-5 years to produce and distribute the vaccine worldwide.
