Wow. How ill informed?

"Protect you against variants"

Definitely not what I hear. Natural immunity would 100% stop C19 in its tracks, and make it impossible for you to transmit the condition.

But geepers: she had "asymptomatic Covid19".

If she tested, she find she also has asymptomatic chicken pox.

What is a Covid19 “case”?

What is a Covid19 “case”? The term has been completely redefined in the era of COVID, but no one has notified the population that the meaning of the word has been substantially changed. Pre-COVID, a “case” was a person experiencing symptoms of illness warranting medical attention. 

Post-COVID, a “case” is anyone with a positive PCR test, most of whom do not experience symptoms warranting medical attention. This is a huge change in language that biases the emotional fear response when discussing “cases”. 
The thing that is utterly mystifying to me is why these death counting and “case” counting methodologies were chosen at all. Even a science undergraduate with relatively limited training in measurement would be aware they were basically “throwing the measurement book out the window” by choosing these methods. 

Yet these methods were supposedly established by experts at the highest levels of the scientific hierarchy, and yet they made such egregious and fundamental violations of basic measurement practice? What on earth is going on here? 
I will highlight the absurdity further. If we consistently apply the aforementioned definitions of “cases” and “deaths”, then that means that the world is currently in the midst of a enormous chickenpox and shingles global pandemic that dwarfs COVID-19. 

If we were to extensively PCR test for the causative virus, varicella-zoster, we would find that almost everyone older than 10 years of age has the virus [KOWITDAMRONG2005]. Chickenpox can kill and shingles is incredibly painful. 
To further illustrate the madness of these central COVID metrics, if we were to count “deaths” from our “chickenpox pandemic” using the same method as much of the world counts “COVID deaths”, we would discover that almost every death globally in the past 12 months would be a “chickenpox death”. The moral of this story is this: measuring with deeply flawed methods is guaranteed to yield deeply flawed and misleading results.
