Kaко што реков постоење и функционирање на имунитет се фундаментални факти.
Смешно е што се обидуваш да аргументираш против егзистенција на нешто фундаментално како имунитет. Неколку истражувања што покажуваат некаков маргинален процент на реинфекција со ковид19 не се доказ против имунитетот.
Во однос на другото ја поздравувам секоја одлука да не се дискутира нешто што не е можно аргументирано да се одбрани. Личните напади понатаму нема потреба да ги коментирам.

Целосно глупаво е да дискутираме дека стекнат имунитет не функцинирал.
