BACKGROUND Current influenza vaccines based on the hemagglutinin protein are strain specific and do not provide good protection against drifted viruses or emergence of new pandemic strains. An influenza vaccine that can confer cross-protection against antigenically different influenza A strains is highly desirable for improving public health. METHODOLOGY/PRINCIPAL FINDINGS To develop a cross ...
A persistent infection with human papillomavirus (HPV) is a prerequisite for the development of cervical cancer. Clinical trials with HPV-vaccines have been very successful in preventing persistent HPV16/18 infections, the two most oncogenic HPV-genotypes. We assessed the introduction of universal HPV-vaccination for preadolescent girls in the Dutch National Immunization Programme. Long-term va...
The question whether a vertically and a horizontally transmitted parasite strain can coexist under complete cross protection is investigated in a host-parasite model with susceptibles and infectives only. It is shown that coexistence is possible even if the vertically transmitted strain would go extinct on its own provided that it is considerably less virulent than the horizontally transmitted ...
In 2007, the Victorian influenza season exceeded normal seasonal activity thresholds. The average rate of influenza-like illness (ILI) reported by general practitioners (GPs) participating in sentinel surveillance was 9.0 cases per 1,000 consultations, peaking at 22 cases per 1,000 consultations in mid-August. The average ILI rate reported by the Melbourne Medical Locum Service (MMLS) was 11.5 ...
We hypothesize that the perceived returns to human capital and to income uncertainty are important determinants of recent cross-sectional variation in Latin American fertility. An empirical study of cross-country individual level data supports the hypothesis. In particular, we find that a higher perceived return to human capital and higher income uncertainty both lead to higher fertility, all e...
OBJECTIVES The objectives are to investigate radiology practitioners' and radiographers' radiation dose awareness and use of referral guidelines for paediatric imaging examinations. METHODS A prospective cross-sectional survey was conducted amongst radiology practitioners and radiographers working at a primary paediatric referral centre in Malta. Part of the survey asked participants to indic...
