COVID-19 vaccine



Vaccine development for SARS COV2: -
(reverse vaccinology approach.)

The approach that we can take to develop vaccine is that we can identify the structure of the surface proteins present on virus and find the genome sequence responsible for the production of these proteins and can engineer the DNA sequence of it by using the recombinant DNA technology.
We can copy the DNA sequence to make a huge number of it by the PCR method which will then be utilized to make proteins in another organism from where we would extract the proteins.

These proteins will be given along with the adjuvants (i.e. substances that increases the efficacy of vaccine).to the patient so that the patient’s immune system can develop an immune memory which will be utilized whenever a virus attack.
Two companies the Sanofi and the GSK have collaborated to develop vaccine against the SARs COV2.
1)       In this collaboration the Sanofi will be contributing the S-protein COVID-19 antigen which has been obtained by using the recombinant DNA technology. This technology has produced an exact genetic match to the proteins present on the viral surface and the DNA sequence encoding this antigen has been combined into the DNA of the baculovirus expression platform, the basis of Sanofi’s licensed recombinant influenza product in the US.
2)      GSK will contribute its proven pandemic adjuvant technology to the collaboration. The use of an adjuvant can be of particular importance in a pandemic situation since it may reduce the amount of vaccine protein required per dose, allowing more vaccine doses to be produced and therefore contributing to protect more people.

Recombinant DNA technology

Recombinant DNA Technology     The term recombinant DNA means the joining or recombining of two pieces of DNA from two different sources. Genetic modification using recombinant DNA allows us to move genes whose function are known. By making manipulations more precise and outcomes more certain, the risk of producing organisms with unexpected traits are decreased. ·         Steps involved in recombinant DNA technique (or gene cloning): - ·         The basic 7 steps involved in gene cloning are: Isolation of DNA [gene of interest] fragments to be cloned. Insertion of isolated DNA into a suitable vector to form recombinant DNA . Introduction of recombinant DNA into a suitable organism known as host. Selection of transformed host cells and identification of the clone containing the gene of interest. Multiplication/Expression of t...

KADAMBANI GANGULY

  THE FIRST FEMALE DOCTOR OF INDIA Our human society has a norm of following set patterns. We follow pattern in all of our work in all of our habits, in all of our social interactions. And one of the examples that adds to this pattern is to consider women as a weak gender. It’s not a sudden thing that has emerged today but it’s has been there since the beginning of the human society. The basic rules of the society that we follow today has emerged from a patriarchal thinking so naturally women had always been kept at a disadvantage in terms of power, in terms of empowerment. Many women in our history have tried to break this pattern by doing extreme hard work, by facing hard resistance, by overcoming the social stigma of the society and tried to make gender equality a part of this civilization. One such lady was Kadambini Ganguly, the first Women Physician of India at a time when the Indian society used to think women education as an offence. Kadambini Ganguly was born on 18 ...

Plastic Pollution: Understanding the Threat of Microplastics

Microplastics- These are the pieces of plastics that are less than 5mm in size and are present in the environment from various sources of plastics. Humans couldn’t have possibly imagined that a simple invention back in 1909, by “Leo Hendrik Baekeland” called the Bakelite (the first synthetic plastic – “phenol formaldehyde resin”), could become a threat to the environment. The commercial success of this product lead to inventions of many more plastics like LDPE, HDPE, PVC, Polystyrene etc.  After this human have accepted plastics so fast that we can easily see how dependent we have become on the plastic.  The global plastic industry in 2020 was valued at 580-billion-dollar industry. Plastics are now everywhere and in every industry. Why is plastic becoming a problem to us? There are many perspectives to this, but I will discuss 3 of them.        The non-biodegradable nature of the plastic.        Accumulation of microplastics in foo...
