Treating Corona Virus The Story of Antibiotics, Antibodies, Biologics and Vaccines. The medical establishment is racing to find a cure for the corona virus or to at least find ways to lessen its impact and to prevent another epidemic next year. During the extensive coverage of the corona virus pandemic, we are hearing much talk about Antibiotics, Biologics, and Vaccines. Let’s take a closer look at these modalities. Antibiotics are drugs that work against organisms such as bacteria, viruses and fungi and are referred to as antibacterial, antiviral or antifungal respectively. Antibacterial Antibiotics: A well-known example of an antibacterial antibiotics is penicillin.

I mean the genes that make up  your  DNA. ”   They are here ,  I said.   In the field of medicine, the 21 st  century is going to be gene therapy century. Genomics like other “omics”, is a field that deals with individual genes or the whole genome. Gene therapies are medical treatments that are based on abnormalities in the genes. These genetic defects can be inherited such as sickle cell disease or acquired such as cancer.    Today, we are at the cusp of making many of such  diseases, a  thing of the past.   Until the turn of the century, most of the medicines were made by chemists by mixing chemicals. Such a toxic brew of chemicals was first tested on live cells in a petri dish, then on little mice, followed by bigg...
