Consider immunization strategies discussed in the context of network epidemics. Which of the following statements is incorrect?

  1. Random immunization performs poorly in scale-free networks because it rarely targets highly connected hubs.
  2. Targeted immunization raises the epidemic threshold by removing the hubs responsible for rapid spreading.
  3. Random immunization always outperforms targeted immunization in networks where \(\langle k^2\rangle\) is finite.
  4. Immunizing a randomly selected neighbor of a randomly chosen individual tends to target high-degree nodes due to the friendship paradox.
  5. None of the above
