I was actually a little hesitant about writing what I wrote. In fact, when I was getting the news from my friend first I said:
"If it's a bad reaction I don't want to know because my mind will make my body react that way!" then I said: "Well, I DO want to know if it's been everybody you know (it was three persons)!" and now I say: "It's worth knowing but don't believe it's a given thing. Half the time it's a way people have to convince themselves that it's the real vaccine and it will really work."
