The authors argued that there is a need for increased focus on VPDs from the angle of international medical science. This should really be well understood especially if the child is below five years of age. These diseases, which are preventable due to vaccines, contribute greatly toward suffering and death – especially in LMI nations. This is more so given that other national factors such as, national average income per capita is relatively low. And this is the status that prevails especially in the countries where the overwhelming majority of the population continues to inhabit a limited territory. In the course of this consideration, a great deal of information concerning the impacts of VPDs is provided. The discoveries of this investigation add to our knowledge about the benefits of vaccination, which are accrued through vaccine administration plans, as well as the risks associated with low immunisation rates among the public over time. Thus, LMICs need to persist in their population’s immunisation against diseases that can otherwise be prevented by use of vaccinations and strive to enhance the availability of some vaccines. Now there is a need to go further in the immunisation program, and make more vaccines available to the public. Therefore, important questions like accessibility and costs of the vaccines have to be answered in order to achieve the goals of raising the vaccination rates and, therefore, lowering the rates of diseases that may be prevented. Unfortunately, we will not be able to achieve this goal if we opt to ignore these hindrances or fail to respond proactively to address them. Thus the key strategy to      protect the emotionally volatile and physically fragile people and avert immunity gaps, in respect to VPDs, is to conduct constant surveillance and identification of the situation, offering individual approach to treatment. We may do this in several ways, although we are not limited to the following; we can ensure that there is a provision of shields that would shield the vulnerable groups from the risks associated with the VPDs.
