Immunity, you must have come across this word so frequently amid this pandemic that you might even ignore it. But again, we are gonna ask you the very same question that you hear on television and every other social media platforms everyday.

So, what is immunity? What decides whose is stronger and who’s not?

Do you know! No, not the common folks but you, the medicos. Do you know??

Well, of course you’ll say, Immunity is the ability of the human body to recognise any foreign antigen and neutralize it. This isn’t a hard question, right?

But we ask again, what is immunity? The above is it’s function. But what exactly is it?

Many people might not internalize what we intend to say… So, let’s get it a bit simple for you.

Consider a man who’s painter by profession, Painting is his work but it doesn’t define the man.
We may add that immune system consists of cells, cytokinesis , signalling molecules etc etc .
These are like the paint brushes and colour to that artist (Tools or means by which work is
achieved). But again they fail to describe the artist the driving force or the working power.

This could be an argument, perhaps the DNA is the driving force. Well, we will surely look up to this in our further discussion.

Let’s for now jump to the second question. What decides whose immunity is better?

So, we personally asked this to many of our seniors and batch mates and have gone through various articles and text. But they couldn’t lead us to any satisfactory answer. What we gathered from all our research and acceptable logics were these:

  1. Recurring infection
  2. Opportunistic infection
  3. Eating habits
  4. Environmental factors
  5. Genetic constitution

These above could be the parameters when we are to access or examine the immunity between two individuals.

So to get this done let’s perform something that the greatest scientist of the century called ‘A Thought Experiment’.

Consider a set up with four persons: A, B, C and D. Wherein persons A and D are healthy those don’t get ill so frequently but persons B and C on the other hand gets infected very frequently. They are exposed to various infections and are left with their immunity to fight with it.

Infections encountered Person A

(Oral polio vaccine given)

Person B

(Hepatitis B vaccine given)

Person C

(No vaccine)

Person D

(No vaccine)

Polio virus Normal Normal Diseased Diseased
Hepatitis B Diseased Normal Diseased Normal
Typhoid Recovered Dead Recovered Dead
Malaria Dead Recovered Dead Recovered

If we take polio as the basis then B seems to have best immunity but it’s D if we gonna choose Hepatitis B infection.

All we want to say is that we cannot decide this on the basis of getting infected or not, able to fight it or not (also considering the fact about vaccine immunity). It makes no sense!! There is no definite conclusion even when only 4 infections are being considered, what if we considered 1000s others too. It will all surely be a mess.

Well, the results of this experiment are completely arbitrary. You are free to create any set of results or outcome of your choice after all it’s your thought experiment.

But any set of outcomes will tell you, this isn’t perfect, you can’t be sure of it. Everything is too relative here.

What we want to say, is simply whether someone gets infected or not by 2,3 or 4 type of infections doesn’t decide what sort immunity he holds within. This concept is more fundamental and minute. There should be something more absolute than this relativeness. Is there an ABSOLUTE IMMUNITY?
