Netlogo : Vaccinating different breeds

My model is representing the spread of influenza through two separate breeds adults and children.

What I would like to do is add separate vaccinations for adults and children, allowing me to specify two vaccination values from the interface giving the chance of the two respective breeds turtles being vaccinated

My current code is below, what I want to be able to do is use the interface value adult-vaccination to vaccinate a percentage of the turtles in that breed.

ask turtles with [ adult? = true ]
   [
   if (adult-vaccination = 1) 
   [
    reset-node
    set exposed? false
    set susceptible? false
    set temp-infected? false
    show-turtle
    set color pink
    ]
    ]

If adult-vaccination is a probability from 0 to 1, you can probabilistically vaccinate adults like so:

ask turtles with [ adult? ] [
  if random-float 1 < adult-vaccination [
    ... ; vaccination code here
  ]
]

If you want adult-vaccination to actually determine the fraction of the population that is vaccinated, you can do that like so:

let adults turtles with [ adult? ]
ask n-of round (adult-vaccination * count adults) adults [
  ...; vaccination code here
]

A few other tidbits:

  • variable = true will be the same as variable if variable is always true or false.
  • This looks like a perfect opportunity for using breeds. You would have an adults breed and children breed. Then you can do things like ask adults [ do stuff ] and give adults and children different variables, etc.
