2. WHO considers it one of the essential medicines.
The World Health Organization functions as one of the worldwide watchdog organizations for the healthcare industry, and for this, they’ve set up a list of essential medicines that are recommended for the inventory of every country in order to keep their people healthy – and the very essential polio vaccination happens to be on the list.
Other essential medications also on the list include things like ARV medication and general painkillers such as paracetamol and aspirin; these are medications that can be applied to a broad range of healthcare uses and are therefore considered to be some of the most essential ones.
Because of the fact that WHO has it listed on their catalog of essential medications, access to the polio vaccine has gotten much easier over time, which in turn means that the number of cases has been able to be greatly reduced to the point where we no longer see the large-scale polio outbreaks that we used to a few decades back.
