Add the possibility to explicitly set the number of vaccinations

[imcatta]

Is your feature request related to a problem? Please describe.

Most countries make available data on the number of vaccinations carried out. Currently, it's hard to calibrate Covasim using those data, because the vaccinate() intervention works based on the prob parameter.

Describe the solution you'd like

It would be very useful to add the ability to explicitly set the number of vaccinations per day, similarly to the test_num() intervention. In addition, it would be important to retain the ability to target a specific subpopulation.

Describe alternatives you've considered

Use the subtarget parameter to explicilty target people, but it's hard to make it work if dynamic rescaling is on.

Thanks @imcatta ! We are aware of this and it didn't quite make it into the 3.0.2 release, but we're hoping it'll make it into the 3.0.3 release :) (Not sure exactly on what timeframe, but let's say about a week.)

Any updates? :)

@imcatta Sorry, it took a while! But this was part of the Covasim 3.0.6 release last week, a new intervention called cv.vaccinate_num():
