I am not a medico, but I once thought that if one got vaccinated, you would have immunity from the disease. That means, as I understand it, you would not, or most likely would not, get the disease if exposed to it. Isn’t that how the word “immunity” is used in other contexts, like legal immunity? So, how can breakthrough infections occur at all? Nothing is perfect, but this is a question of whether the blasted things do their job. Take the UK for example. The latest data from Public Health England shows from February 1, 2021 to September 12, 2021, the unvaccinated represented just 28 percent of the Covid fatalities while the vaccinated represented 72 percent of the deaths! If that is not “fishy” then nothing is. The system saying that this shows that nothing is perfect is no answer. Maybe “nothing” is preferable?
