The constructor with `_disableInitializers()` runs on the implementation contract, whereas the `initialize()` function runs in the context of the proxy. See [Is \_disableInitializers necessary? - #2 by ericglau](https://forum.openzeppelin.com/t/is-disableinitializers-necessary/31070/2) for reasoning.

> In any case, I've included `_disableInitializers();` in my parent `constructor` , should I also include it in the child `constructor` as well

If it's already in the parent, it's not necessary to include it in the child.
