How long does it take for hard immunity to develop, or when to get vaccinated?

Coronavirus vaccine-How does the immune response work in the case of corona? Will hard immunity precede the vaccine?

6 minute read

Scientists believe that one of the conditions for losing the coronavirus is to develop hard immunity or group immunity. Doctors believe that if the lockdown is done, the infection will be under control. But in that case, they also think that the lockdown needs to be effective in the real sense.

Research on coronavirus vaccine: when to get vaccinated?

Assuming that the number of infections continues to rise, there will come a time when the rest of the population develops immunity to the germs involved. is that really so? wonder news Digital spoke with Dipyaman Gangopadhyay, a scientist and immunologist at the indian institute of Chemical Biology.

How does the immune response work in the case of corona?

This novel coronavirus has spread rapidly around the world. At first there was skepticism, however, as to whether there was a sufficient immune response (a reaction is formed when the body is unable to identify any object present in the body's cells and blood or thinks it is something unknown).But over the past six months, there has been a significant immune response to the virus. Antibodies have been created. T cells are also attached at the same time.

A recent report from the UK found that after 2-3 months there is no antibody response (when an object enters the body from outside, the body produces a response due to that antigen, resulting in rapid antibody production).

In the last 9 months, the number of infections has exceeded two and a half crore worldwide. However, once infected, there is no risk of infection for at least 9 months. it is seen that the antibody response decreases within 2-3 months of infection. That has also created an atmosphere of apprehension.But this suggests that T cells, like the antibody-producing B cells, have played a vital role in the fight against SARS COV-2, since the number of re-infections is not very high. This theory is very important to the scientists who are developing the vaccine.

Why is group immunity important?

Grouped immunity provides protection for large populations. Those who are more at risk of becoming infected will be much better off if hard immunity is created. Creating hard immunity will also reduce the rate of infection. But keep in mind that it is not clear how long this hard immunity will provide protection.According to the latest statistics, that is nine months, because in the last nine months we have not found any evidence of re-infection at alarming levels. if i don't hear of a massive relapse in that sense a couple of months later, then the period can be assumed to be 11 months. Scientists have no choice at the moment.

The number of infections is increasing day by day. So immunity is very important.

The reason for the rapid spread of the infection is that the Ro standard (a measure of how many healthy people an average infected person can infect) is too high. As a result, the magic number of hard immunity can be found very quickly, that is, group immunity. But it will only be effective if the disease is chronic.

Will hard immunity precede the vaccine?

Considering the way the virus is spreading rapidly, as well as the time it takes to make a successful vaccine, hard immunity will prevail. This means that the immune system will be developed before a proper vaccine arrives. Many experts may not agree, but once grouped immunity is developed, it will be helpful later. However, in that case the duration of immunity should be relatively long.

Can hard immunity be built faster? if so, how?

in the case of large populations, group immunity or hard immunity develops as a protective immune system. it can be caused by a natural infection or by a vaccine. The duration of reaching hard immunity is proportional to how fast the infection spreads and in the latter case it is proportional to how many people were vaccinated.There is also a mathematical model of how much immunity is created in a part of the population, which helps in building hard immunity.

In 60-70% of SARS Cove-2 cases, the value varies. Dipyamanbabu said his idea is that in the case of this model, all members of the population can be infected equally. But that doesn't seem right. The majority of the population may not be infected just for their livelihood. Such as older members of the household. in that case, the target is further reduced.

Why is there so much panic about this disease? Say it spreads fast?

Of course. There are actually very few examples in the history of civilization where a disease has spread so fast. in two months, seven continents and in eight months, about two million people have been infected. A big cause of panic is uncertainty. it is unknown at this time what he will do after leaving the post. it's a good thing that kids are less affected. The severity of the disease is slightly lower in women.

What is the death rate and recovery rate of this disease in the world?

There are more than two and a half crore recorded infections in the world at the moment. About two crore people have recovered. More than 6 lakh people have died. The death rate is close to 5 percent. But during this calculation, it is important to keep in mind how many people have been infected and how many have died. A large part of the population but infected. However, in that sense, there are no symptoms and they do not fit in the statistics, it must be remembered.So the death rate is even lower than it seems.

Corona virus can counteract group immunity: Photo coronavirus

Is this disease the same as the other five flu?

Absolutely not. in the case of other flu, the infection does not spread so fast or there is not so much panic among so many infected people.

Is SARS Cove 2 more harmful than other flu viruses?

Assuming yes. Because those who are more horrible, they have become much sicker. it is unknown at this time what he will do after leaving the post. So more research is needed on this in detail.

In a country like india with a population of 135 crore people, even if 30 per cent of the population is infected, the potential number of infected patients in the country could be 40.59 crore. what do you say in this context? in the words of Dipyaman Babu, it is a matter of concern. And that is why not only india, but the whole world is eager for the vaccine. But as long as the vaccine is not coming, the group infection cannot be stopped. So it is wise to understand what is waiting for us in that case.
