It has recently been confirmed that once a corona is infected, the person may be infected a second time. It is not certain that the Kovid-19 virus will not attack once you have recovered from Corona. At least several recent events do not say that. Now in this context, the importance of the vaccine is being questioned. How do you get coronary heart disease for the second time after vaccination?
We all know that a vaccine is basically a dormant virus that is injected into the body to build immunity against the original virus. If the vaccine is given before it is infected, the body will recognize the coronavirus as soon as it attacks and will try to destroy the virus by instinct.
Now the opposite is being said about the vaccine. If the body develops immunity after the coronavirus attack, then where is the need for the vaccine? There is a need. The importance of the vaccine is increasing even after recovering from the corona. But the re-attack of the corona in Hong Kong earlier this week has cast doubt on the vaccine's work. Another thing the researchers noticed was that the more severe a person's coronary infections and symptoms, the better their immune system.
Once the human body begins to develop immunity, it remains in the memory of the T-cell. This is the innate ability. It is unknown at this time what he will do after leaving the post. Bigger than that, even though the person in Hong Kong was vaccinated with the corona, but his report came back positive. This time the question is how much protection the vaccine will give.
Science will never say that once the vaccine is given, the virus will be eradicated. Because often it is not possible. Some vaccines have to be given more than once. Such as polio in children. After being vaccinated for a certain period of time, the body gradually develops a strong protective zone against the disease. Since all the vaccines are still on trial, it may not be possible to answer this question right now. Source: The Indian Express
Hope that the vaccine will be in market soon
