We derive the distribution of the number of infections among unvaccinated and vaccinated individuals for model 1 (leaky) and model 2 (all/nothing) vaccines, assuming random mixing of a homogeneous population. For all/nothing vaccines, we show that the distribution of the number of infected vaccinated individuals conditioning on n observed infections follows a hypergeometric distribution, and th...
In 2013, 15 clusters of mumps were notified in France; 72% (82/114) of the cases had been vaccinated twice with measles-mumps-rubella vaccine. To determine whether the risk of mumps increased with time since the last vaccination, we conducted a case-control study among clusters in universities and military barracks. A confirmed case had an inflammation of a salivary gland plus laboratory confir...
Universal infantile hepatitis B virus (HBV) vaccination may lead to an increase in vaccine escape variants, which may pose a threat to the long-term success of massive vaccination. To determine the prevalence of occult infections in Korean vaccinated individuals, 87 vaccinated subjects were screened for the presence of HBV DNA using both the nested PCR protocol and the VERSANT HBV DNA 3.0 assay...
OBJECTIVE To highlight the complications involved in interpreting laboratory tests of measles immunoglobulin M (IgM) for confirmation of infection during a measles outbreak in a highly vaccinated population after conducting a mass immunization campaign as a control measure. METHODS This case study was undertaken in the Republic of the Marshall Islands during a measles outbreak in 2003, when r...
This study sought to understand the social representations of health and immunization for elderly individuals vaccinated and unvaccinated with influenza vaccine. The theoretical benchmark adopted was the Theory of Social Representations of a qualitative nature. The research was carried out with thirty elderly individuals, fifteen of whom were vaccinated against influenza and fifteen who were no...
Tuberculosis (TB) infections in India account for one-third of the global burden, making it important to develop speedy, cost-effective diagnostic tools. This study evaluated recombinant RD1-encoded antigens of Mycobacterium tuberculosis as tools for serodiagnosis by determining the immunological reactivity of these proteins against sera from healthy, bacille Calmette-Guérin (BCG)-vaccinated an...
BACKGROUND The outbreak of Zika virus (ZIKV) infection in Brazil has raised concerns that infection during pregnancy could cause microcephaly and other severe neurodevelopmental malformations in the fetus. The mechanisms by which ZIKV causes fetal abnormalities are largely unknown. The importance of pre-infection with dengue virus (DENV), or other flaviviruses endemic to Brazil, remains to be i...
INTRODUCTION Zostavax, a live attenuated vaccine, has been approved in the United States for use in older individuals to reduce the risk and severity of herpes zoster (HZ), also known as shingles. The vaccine is contraindicated in individuals taking anti-tumor necrosis factor alpha (anti-TNF) therapies or other biologics commonly used to treat autoimmune diseases because of the safety concern t...
Since beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), different variants concern (VOC) have been discovered. One that stood out was Delta variant (B.1.617.2), first found in India. It caught worldwide attention due to its greater transmissibility than progenitor strain and (VOC)- Alpha (B.1.1.7). B.1.617.2 spread rapidly across globe became a VOC high transmissibi...
BACKGROUND rVSV-ZEBOV is a recombinant, replication competent vesicular stomatitis virus-based candidate vaccine expressing a surface glycoprotein of Zaire Ebolavirus. We tested the effect of rVSV-ZEBOV in preventing Ebola virus disease in contacts and contacts of contacts of recently confirmed cases in Guinea, west Africa. METHODS We did an open-label, cluster-randomised ring vaccination tri...
