Dear Editor, The word that has engulfed the world the most in the last nearly two years is Vaccine. Governments worked hard to achieve this, the arrangements made for its supply in every corner of the world united day and night, risking their lives, medical workers engaged in the work of vaccination and people got it installed. Here we have left the most important link of these vaccines to the scientists, because the rest have taken a sigh of relief after completing their work, but the scientists still did not get this opportunity. They are the scientists who were first involved in this work and they are the scientists who are still engaged in it. It was the scientists who showed the first ray of hope through their activity, and they are the scientists whose activity is going to continue till we are completely sure. The work that has been done in the last two years regarding the vaccine and its effects in world, perhaps was never before. That is why in the last few days, many researches have come out, which clear many of our doubts about the natural immunity of the epidemic and the immunity of the vaccine. The question has been raised for a long time whether the vaccine is more effective or herd immunity. Conventional thinking says that the development of natural immunity is more important than the vaccine. Therefore, whoever got COVID, doctors kept advising not to get the vaccine until sometime after that. The thinking was that in such a situation there is no immediate need for a vaccine. But the new research that is coming out tells a different story. Research from Washington University School of Medicine suggests that even if you have natural immunity, you still need the vaccine. Research has found that the body needs a lot of energy to produce antibodies on a large scale. The body cannot do this work for a long time, so it quickly reduces their number. Therefore it is necessary that anti-bodies are taken from outside, and this work can be done only by the vaccine. On the other hand, scientists at Stanford Medicine have found that due to COVID vaccines, those lymph glands of the body are activated, which helps in the production of antibodies. Whereas a study by Tel Aviv University is showing that those who got the vaccine were found to have 0.4 percent chance of getting COVID again, while those who did not get this fear was found to be 3.3 percent. For this research, more than 83 thousand patients were studied. From these researchs, we can also understand how the third wave of COVID was dealt with so easily in India and the rest of the world. These studies have come at a time when the World Health Organization is constantly warning that the time has not come to relax the restrictions of COVID too much, as wearing masks, maintain social distancing and vaccination is still very important.
