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.

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...

The story of journey and not the destination

The UPSC results are out. So many success stories are coming out from this event and every story is unique and inspiring. But out of all these, one story that grabbed my attention is a story of the person who is not an IAS yet but has secured 667 rank and is still preparing for the UPSC exam for a better rank and this years attempt will be his last attempt the 9th attempt. The story of RAM BHAJAN KUMAR, 34 years old, head constable in Delhi Police. He is a married guy and father of two daughters. While reading the story of this I was so touched and inspired that I felt like sharing it.  He has seen many economical hardships and despite of everything he wants to motivate and help people and according to him UPSC gives that platform to motivate and help people. When he got married his wife was a fifth pass, Time has passed and the best thing is she began the journey of becoming a post graduate. The kind of support and devotion this person showed towards his wife and how they both gre...
