IndividualImmunityChanger

The IndividualImmunityChanger intervention class acts essentially as a MultiEffectVaccine, with the exception of how the behavior is implemented. Rather than attaching a persistent vaccine intervention object to an individual’s intervention list (as a campaign-individual-multieffectboostervaccine does), the IndividualImmunityChanger directly alters the immune modifiers of the individual’s susceptibility object and is then immediately disposed of. Any immune waning is not governed by Waning effect classes, as MultiEffectVaccine is, but rather by the immunity waning parameters in the configuration file.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. JSON does not permit comments, but you can add “dummy” parameters to add contextual information to your files.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Parameter Data type Minimum Maximum Default Description Example
Boost_Acquire float 0 1 0 Specifies the boosting effect on acquisition immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine. This does not replace current immunity, it builds multiplicatively on top of it.
{
    "Boost_Acquire": 0.7
}
Boost_Mortality float 0 1 0 Specifies the boosting effect on mortality immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine. This does not replace current immunity, it builds multiplicatively on top of it.
{
    "Boost_Mortality": 1.0
}
Boost_Threshold_Acquire float 0 1 0 Specifies how much acquisition immunity is required before the vaccine changes from a prime to a boost.
{
    "Boost_Threshold_Acquire": 0.0
}
Boost_Threshold_Mortality float 0 1 0 Specifies how much mortality immunity is required before the vaccine changes from a prime to a boost.
{
    "Boost_Threshold_Mortality": 0.0
}
Boost_Threshold_Transmit float 0 1 0 Specifies how much transmission immunity is required before the vaccine changes from a prime to a boost.
{
    "Boost_Threshold_Transmit": 0.0
}
Boost_Transmit float 0 1 0 Specifies the boosting effect on transmission immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine. This does not replace current immunity, it builds multiplicatively on top of it.
{
    "Boost_Transmit": 0.5
}
Prime_Acquire float 0 1 0 Specifies the priming effect on acquisition immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine.
{
    "Prime_Acquire": 0.1
}
Prime_Mortality float 0 1 0 Specifies the priming effect on mortality immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine.
{
    "Prime_Mortality": 0.3
}
Prime_Transmit float 0 1 0 Specifies the priming effect on transmission immunity for naive individuals (without natural or vaccine-derived immunity) for a multi-effect booster vaccine.
{
    "Prime_Transmit": 0.2
}
Cost_To_Consumer float 0 999999 10 The unit cost per vaccine (unamortized).
{
    "Cost_To_Consumer": 10.0
