You must have read my earlier blog related to how the SARS CoV2 infects the lungs and causes death. This is a continuation to that article. You would get a vaccine that contains faint version of a virus. The vaccine then exposes you to a version of virus (yet to be developed) that is too weak to cause an infection but just strong enough to stimulate an immune response. Within a few weeks, cells in your immune system would make markers called antibodies which would be specific for only the Coronavirus or specifically for it's spike protein. Antibodies then attach to the virus and prevent it from attaching to your cells. Antibody attaching to the virus                     Your immune system then responds to signals from the antibodies by consuming and destroying the clumps of viruses. Immune system responding to the virus If you then catch the virus at a later stage, your body would recognize it and then destroy it. In other words, your immune system is now immune

SARS-CoV2 causes COVID-19. It is a contagious viral infection that attacks primarily one's throat and lungs. It belongs to the family of Coronaviruses. It is named for the crown-like spikes on it's surface. Electron Microscope image of Coronavirus What happens in the body when you contract coronavirus? It is the primary task of every living creature to look for ways to maintain it's existence. This can be done by reproducing. In order to reproduce, the coronavirus must infect living cells. Inside a virus, genetic material contains information to make more copies of itself. Parts of a Virus    A protein shell provides a hard protective enclosure for the genetic material as the virus travels between the people it infects. An outer envelope allows the virus to infect cells by merging with the cell's outer membrane. Projection from the outer membrane are spikes made of protein molecules. Both influenza and n-coronavirus use their spike

The Chinese Virus 2019 originated in China but at present, the epicenter of the disease is not China but Europe and United States. There is a huge population of Chinese people who live in the US for either Job or educational purposes. They want to return to their home country. So there is a sudden increase in traffic which led the Chinese government to cancel visas. As a result of this, no one can enter China after 28th March 2020. There is a complete ban on foreign visitors plus the Chinese non-residents of China. Once a week, flights have been allowed from each country but with a few restrictions; flights shouldn't be fully loaded due to social distancing norms (75% full). China said it is being done due to rapid spread of Covid-19 across the world. As no foreign visitors would plan a tour now, the decision won't affect them. It's only the Chinese airlines  which are flying between the routes. The entry for people with diplomatic, service, courtesy (ones called by

Once there was a hare and a tortoise (yeah yeah, your primary school friends). Now they are no longer in UKG, have grown up and now have started star-gazing. Hare: Do you see that torti? Look there! There's the moon. Tortoise: Yeah! He's all shiny and bright. Ready to be eaten with bread and butter. Hare: And do you see the shiny star beside it? It's actually not a star. It's Venus. Hare: Wo...ho Harry! Do planets too shine like stars? Hare: They reflect, like the big shiny bright moon. Tortoise: Aha...and do you see that Harry? The one over there. The tortoise pointed his index finger towards a faint star in the deep sky. Hare: Where? Is it over there? Hare too tried to point towards exactly the same star as the tortoise. Tortoise: Yeah! That one.      I, the author, projected their tiny arms on the astronomical scale. It passed through deep space and when they finally reached the destination, lo, it was like one pointed in the east and one in the wes
