Before revision:  In particular, powerlaw graphs do not retain their structure after a few waves of infection, which implies second and third waves may be of much smaller amplitude than the first wave. We propose an opening and closing strategy aiming at immunizing the graph while infecting the minimum number of individuals, while guaranteeing the population is now robust to future infections.
