english: But it's not one virus, it's four, and the same protection that gives you the antibodies and protects you from the same virus that you had before actually makes you much more susceptible to the other three.
non_english: Ali ne postoji jedan virus, već četiri, a ista zaštita koja vam daje imuno tela i štiti od istog virusa koji ste imali ranije, zapravo vas čini podložnijim ostalim trima virusima.
