A virus is trained to be stealthy. In the battlefield of the human body, it has no weapons nor reproduction machinery but has the Master Key built-in, with which it can hack the cells’ smart wall, which is the cell membrane. The key is built around an envelope of protein, which covers the genetic material. Some contain DNA and some RNA. SARS-COV2 contains RNA. After entering the cell, it hacks the machinery of the cell, and makes it its reproduction mechanism. Then, these clones move out in herds, repeating the cycle, and killing cells in the process of this rampage.
But the immune system also has intelligence. The memory-b cells collect data about the virus in secret and can stay dormant for a long time. Hardworking intelligence indeed! Then come the soldiers, the antibodies- which gain information from these memory b cells, which become active once that particular virus attacks the body again, and also retain information of other attacks by similar viruses and use that in combination to create modified weapons that can effectively kill the virus. The problem however lies in underdeveloped and compromised immune systems. In the young, the antibodies haven’t got enough intel on the viruses and hence don’t know how to effectively combat this notorious virus, but can develop an immunity to the virus. With compromised immune systems, its far more dangerous. The human body is slowly degenerating and all the soldiers are old and some even retired, so it's difficult to kill these viruses. Even if new antibodies are created, they might be busy somewhere else, fighting off another virus and this stealthy virus harms the body while they are distracted in defeating the other virus.
Almost pure ethanol. Use a hand sanitizer with 68-71% of ethanol to destroy its protective layer.
Chloroquine and Life-Saving Drug are some cures as well.
Soap needs to be administered on the exposed area for 20 seconds exactly, as that will destroy the virus completely.Life-Saving
Vaccines are weakened or dead forms of viruses. A vaccine works in accordance to the memory-b cell. The memory b cell learns the viruses’ attacks and weaknesses, and then transposes this information to the antibodies, whenever this virus attacks the body. This could be done with a normal form of the virus, but it would be too harmful. The vaccine although, has side effects, but very minor ones such as you could experience extremely mild symptoms of that particular virus and other very mild symptoms.
There are multiple stages of vaccine development to ensure the final yield has no side effects.
They are: -
Clinical stages -
Phase 1- the small human group trials with a group of 15-20 people
Phase 2-larger trials of about 200 people
Phase 3-trials involving around 1000 people
Phase 4-trials involving hundreds of thousands of people
These steps (from phase 1 to 4) are actually to determine if the vaccine is safe, if it works, is it better than the available vaccines and does it have any other benefits.
There are many other stages as well, preceding these stages such as discovery research and pre-clinical stages and one last stage called regulatory review and approval, after which its shipped to the public.
This takes about 10 years! But people are trying to fast track the process and shorten it to 12-18 months or 1 and a half years.

In basic terms, in this race of developing a vaccine, there are many contenders and no one knows who will come out victorious.
Do not go outside, unless absolutely necessary.
Wear a mask and maintain social distancing if you do
Apply soap for 20 seconds
If you feel any symptoms, quarantine yourself away from your loved ones and call the helpline numbers
Most importantly, do not panic!
