In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

[EX Q]: An RNA-based, non-cytopathic replicon vector system, based on the flavivirus Kunjin, has shown considerable promise as a new vaccine delivery system. Here we describe the testing in mice of four different SIVmac239 gag vaccines delivered by Kunjin replicon virus-like-particles. The four vaccines encoded the wild type gag gene, an RNA-optimised gag gene, a codon-optimised gag gene and a modified gag-pol gene construct. The vaccines behaved quite differently for induction of effector memory and central memory responses, for mediation of protection, and with respect to insert stability, with the SIV gag-pol vaccine providing the optimal performance. These results illustrate that for an RNA-based vector the RNA sequence of the antigen can have profound and unforeseen consequences on vaccine behaviour.

[EX Q]: Bio-aerosols originate from different sources and their potentially pathogenic nature may form a hazard to healthcare workers and patients. So far no extensive review on existing evidence regarding bio-aerosols is available. This study aimed to review evidence on bio-aerosols in healthcare and the dental setting. The objectives were 1) What are the sources that generate bio-aerosols?; 2) What is the microbial load and composition of bio-aerosols and how were they measured?; and 3) What is the hazard posed by pathogenic micro-organisms transported via the aerosol route of transmission? Systematic scoping review design. Searched in PubMed and EMBASE from inception to 09-03-2016. References were screened and selected based on abstract and full text according to eligibility criteria. Full text articles were assessed for inclusion and summarized. The results are presented in three separate objectives and summarized for an overview of evidence. The search yielded 5,823 studies, of which 62 were included. Dental hand pieces were found to generate aerosols in the dental settings. Another 30 sources from human activities, interventions and daily cleaning performances in the hospital also generate aerosols. Fiftyfive bacterial species, 45 fungi genera and ten viruses were identified in a hospital setting and 16 bacterial and 23 fungal species in the dental environment. Patients with certain risk factors had a higher chance to acquire Legionella in hospitals. Such infections can lead to irreversible septic shock and death. Only a few studies found that bio-aerosol generating procedures resulted in transmission of infectious diseases or allergic reactions.

[EX Q]: The plague is an infectious bacterial disease having a high fatality rate without treatment. It has occurred in three huge pandemics since the 6 th century with millions of deaths and numerous smaller epidemics and sporadic cases. Referring to specific clinical symptoms of pulmonary plague the disease became known as the Black Death. This pandemic probably originated in central Asia and began spreading westward along major trade routes. Upon the arrival in the eastern Mediterranean the disease quickly spread especially by sea traffic to Italy, Greece and France and later throughout Europe by land. Until the 18 th century many European cities were frequently affected by other great plague epidemics. The worldwide spread of the third pandemic began when the plague reached Hong Kong and Canton in the year 1894. The gram-negative coccobacillus now designated as Yersinia pestis has been discovered as the causative agent of plague in this Hong Kong outbreak. In the following years the role of rats and fleas and their detailed role in the transmission of plague has been discovered and experimentally verified. Today the plague is still endemic in many countries of the world.
