In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".

Paragraph: Virus infection often results in diverse outcomes. This variability of virus pathogenesis is not well understood. Here we revise theoretical arguments to further our understanding of factors controlling infection and its severity. We propose that variability in these factors results in different clinical outcomes, which ultimately ensure virus reproduction. A link between parasite virulence and its transmission efficiency is a paramount concept in modern epidemiology. The trade-off between these two pathogen's features has been studied and discussed for decades.

Paragraph: The outbreaks of Middle East respiratory syndrome (MERS) previously in Middle East and recently in South Korea have raised serious concerns world-wide, reinforcing the importance of developing effective and safe vaccines against MERS-coronavirus (MERS-CoV). A number of vaccine candidates have been developed on the basis of viral vectors, recombinant proteins, DNAs, nanoparticles, and recombinant MERS-CoV, and some of them have shown efficacy in laboratory animals. However, the paucity of financial support has made it difficult to transfer effective candidates from the preclinical stage to clinical trials. Here, we summarize currently available MERS vaccine candidates and illustrate strategies for future development, with the aim of provoking government agencies and Big Pharma to invest more funds for developing efficacious and safe MERS vaccines.

Paragraph: A number of arenaviruses are pathogenic for humans, but they differ significantly in virulence. Lassa virus, found in West Afri ca, causes severe hemorrhagic fever (HF), while the other principal Old World arenavirus, lymphocytic choriomeningitis virus, causes mild illness in persons with normal immune function, and poses a threat only to immunocompromised individuals. The New World agents, including Junin, Machupo and Sabia virus, are highly pathogenic for humans. Arenaviral HF is characterized by high viremia and general immune suppression, the mechanism of which is unknown. Studies using viral reverse genetics, cell-based assays, animal models and human genome-wide association analysis have revealed potential mechanisms by which arenaviruses cause severe disease in humans. Each of the four viral gene products (GPC, L polymerase, NP, and Z matrix protein) and several host-cell factors (e.g., dystroglycan) are responsible for mediating viral entry, genome replication, and the inhibition of apoptosis, translation and interferon-beta (IFN) production. This review summarizes current knowledge of the role of each viral protein and host factor in the pathogenesis of arenaviral HF. Insights from recent studies are being exploited for the development of novel therapies.
