Critical Frequency of Vaccines

Is there a critical frequency of inoculations that human style social networks such as the nuclear unit could utilize to successfully stop the spread of a supervirus? That is supposing the vaccine has been developed at an ever more modern pace and can't meet overall manufacturing requirement. If the proximity to the spread is a pathway then can divisionary tactics such as the nuclear family find buffer zones by merely inoculating every second child and a single parent who then become the public face. And in zones further back the public faces and odd travellers become the only inoculated priorities.

My neighbors are trying another divisionary tactic of limited exposure in public places!
