Vaccination means protection from COVID: BHU Study

Physicians at IMS, BHU analyse CT scans of patients who underwent COVID treatment

As the world continues to reel under a fresh wave of Covid19 pandemic caused by SARS-Cov-2 virus, vaccinating the most vulnerable and population as a whole are the uphill tasks governments across the globe face today. The virus changed the world and lives of people as never before.

It is generally observed that those vaccinated as per protocol fare well even if they get infected subsequently. This common perception has been further concretized and documented through a study by Physicians in the Department of Radiodiagnosis at the Institute of Medical Sciences, Banaras Hindu University.

The only way to put life back on track seems to be a wide-spread vaccination program which would in turn generate a general resistance against a severe and complicated form of disease, even if the infection occurs.

Many vaccines have been introduced in the market and are being delivered through government sponsored vaccination programs in India and across the world. India is conducting one of the most successful and the largest vaccination programs in the world.

The team of doctors under the leadership of Prof. Ashish Verma and Dr. Ishan Kumar, including Dr. Ram Chandra Shukla, Dr. Pramod Kumar Singh and Dr. Ritu Ojha, provided one of the earliest documentary evidence to confirm the above notion. The study is first of its kind in the country so far. The group compiled their observation in an original research paper which has been published in the journal “European Radiology” which has a high impact factor of 5.3.

The investigators analyzed high resolution Computed Tomography scans of persons infected with SARS-CoV-2 and showing symptoms and subdivided them in three groups, viz. those who were un-vaccinated, those who had received partial vaccination and those who had received vaccination as per protocol.

The variable under evaluation was the CT severity score, whereby differential analysis of the variability on this parameter between the three groups was the outcome.

Notably this work includes data collected from actual patients during their routine treatment, and no external intervention or sampling was performed on/from these persons. The group also took utmost care that there was no breach of patient related ethics and patient privacy, while this study was also approved by the ethics committee of this institute.
