<b>Background and Objective:</b> Tuberculosis (TB) is one of the leading causes of HIV-related death among people living with it. TB occurs more often severe in a weakened immune system, particularly when a patient is infected with HIV. People infected with HIV are 15-22 times more likely to fall ill with TB. In this research, an epitope-based vaccine has been specially designed for people living with HIV, since the current tuberculosis vaccine Bacillus Calmette-Guerin (BCG) has been proven to cause more harm than good in treating patients suffering from poor immune systems. <b>Materials and Methods:</b> The epitopes were selected from polysaccharide-protein of Mycobacterium tuberculosis and protein envelope of the Human immunodeficiency virus. B cell epitopes have been predicted using BepiPred 2.0, while T cell epitopes predicted using SMM, both are provided by Immune Epitope Database (IEDB). <b>Results:</b> This research had designed vaccine combinations for each type of epitopes and types of the pathogen with world population coverage of >85% for MHC class I epitopes and >99% for MHC class II epitopes. <b>Conclusion:</b> With each epitope were selected based on how strong its bond with HLA and how many HLA can bind with it. As this research was done through <i>in silico</i> approach, <i>in vivo</i> test is still needed to guarantee the result of the designed vaccine.

Objective: Babesiosis is a significant haemoparasitic infection caused by apicomplexan parasites of the genus . This infection has continuously threatened cattle farmers owing to its devastating effects on productivity and severe economic implications. Failure to curb the increase of the infection has been attributed to largely ineffective vaccines.

Antigenic peptides (APs), also known as T-cell epitopes (TCEs), represent the immunogenic segment of pathogens capable of inducing an immune response, making them potential candidates for epitope-based vaccine (EBV) design. Traditional wet lab methods for identifying TCEs are expensive, challenging, and time-consuming. Alternatively, computational approaches employing machine learning (ML) techniques offer a faster and more cost-effective solution.

The global dengue outbreak is a significant public health concern, with the World Health Organization recording over 3 million cases and a 0.04% case fatality rate until July 2023. The infection rate is anticipated to rise in vulnerable regions worldwide.
