The term 'natural immunity' has been often used to express post-infectious immunity and differentiate it from vaccine-induced immunity. In practice, this is not necessarily helpful. There is nothing fundamentally "unnatural" in vaccine-induced immunity, and while the minutiae of natural infection and vaccine-induced immunity might differ, this is a quintessentially unhelpful notion.

Despite such an extensive knowledge, immunity is still a field full of secrets. It fascinates and pushes us to develop new research strategies. Sometimes it resembles a fight with an unknown, invisible enemy. Although lately, thanks to the modern technology, this „battlefield” has been quite well recognized.

We were told in one lecture that it was possible to immunize against diphtheria and tetanus by the use of chemically treated toxins, or toxoids. And the following lecture, we were told that for immunization against a virus disease, you have to experience the infection, and that you could not induce immunity with the so-called "killed" or inactivated, chemically treated virus preparation. Well, somehow, that struck me. What struck me was that both statements couldn't be true. And I asked why this was so, and the answer that was given was in a sense, 'Because.' There was no satisfactory answer.

White blood cells and other cells of ours actively seek out and kill foreign microbes. The specific antibodies that we gradually build up against a particular microbe infecting us make us less likely to get reinfected once we become cured. As we all know from experience, there are some illnesses, such as flu and the common cold, to which our resistance is only temporary; we can eventually contract the illness again. Against other illnesses, though—including measles, mumps, rubella, pertussis, and the now defeated smallpox — our antibodies stimulated by one infection confer lifelong immunity. That's the principle of vaccination: to stimulate our antibody production without our having to go through the actual experience of the disease, by inoculating us with a dead or weakened strain of microbe.

Pfizer and Moderna are the best vaccines. They have been out since Dec-2020. Why don't we have them in India yet? Do we not deserve the best? Don't we buy defense equipment from abroad? Is this not a war like situation? Why does the vaccine have to be made here and only here?

I want individuals to have their own insurance. That means the insurance company will have an incentive to keep you healthy. It also means if you don't like what they do, you can fire them. I like being able to fire people who provide services to me. You know, if someone doesn't give me a good service that I need, I want to say I'm going to go get someone else to provide that service to me.

I want to plead to the general public, please ignore the conspiracy theories out there and let's deal with the science. Science has indicated that being vaccinated is the best protection. We have no intention to do anything that would compromise the lives of people or their livelihood and relationship to the economy.

I would recommend it, and I would recommend it to a lot of people that don't want to get it and a lot of those people voted for me, frankly. But again, we have our freedoms and we have to live by that and I agree with that also. But it is a great vaccine. It is a safe vaccine and it is something that works.

I have a fascination with getting my entire country vaccinated. For that we need all the vaccines we can get and we will need them all. Nothing to do with nation of origin.

Illness must be considered to be as natural as health.

[T]here's something about the way we are... vaccinating... who we are vaccinating, what dangers we are pretending don't exist, that suggests that to some set of people, vaccinating... is a good in and of itself. That that is the objective of the exercise, not herd immunity.

If we look at the highly specialized action of our immune system, we will appreciate into what a brilliant tool evolution has shaped us. Each of us has millions of cells that recognize and destroy foreign antigens. Of course, I mean a healthy, well-functioning immune system, because unfortunately – sometimes it fails.

Firefighting is good. That's what's happening right now. But solution is in vaccines. Enough vaccines.It's not which vaccine. Our vaccine. Their vaccine. It's enough vaccines. If we don't have enough, mayhem won't stop. Swallow pride. Accept mistakes. Get 'enough' vaccines.
