Appreciate your informative article. The functioning of the immune system is well elaborated. I have some queries based on my understanding as below:
1. Why for the same delta variant even today more than 90% of the infections are mild or asymptomatic? Why immune system takes response at appropriate time for majority and becomes overwhelmed for others irrespective of age ? I have seen few healthy people also dying.
2. If the asymptomatic people have high viral load and immune system isn’t mounting any response, what is the virus doing inside the body? Is it spreading inside the cells of organs without us even realising? Is this possible?
3. Why vaccinated and unvaccinated people have same viral load as given by some studies?
