Construction of Recombinant Baculoviruses Expressing Infectious Bursal Disease Virus Main Protective Antigen and Their Immune Effects on Chickens. [PDF]

open access: yesPLoS ONE, 2015
In order to overcome the limitations of conventional vaccines for infectious bursal disease virus (IBDV), we constructed recombinant dual expression system baculoviruses with VP2 and VP2/4/3, the main protective antigens of IBDV.

Sex-differential heterologous (non-specific) effects of vaccines: an emerging public health issue that needs to be understood and exploited

open access: yesExpert Review of Vaccines, 2017
Introduction: Vaccines have heterologous effects on the immune system, leading to altered susceptibility to a range of pathogens, and possibly allergy and autoimmunity. Effects are often sex-differential.

Non-specific effects of vaccines: RCTs, not observational studies, are needed: Figure 1

open access: yesArchives of Disease in Childhood, 2012
For more than 15 years, Peter Aaby and colleagues have been studying mortality after infant vaccination in various sub-Saharan African populations and describing ‘non-specific’ or ‘heterologous’ effects of the vaccines on infant death.1,–,11 In summary, Aaby's observations suggest that live vaccines such as BCG and measles reduce all-cause mortality ...

Determinants of BCG scarification among children in rural Guinea-Bissau: A prospective cohort study

open access: yesHuman Vaccines & Immunotherapeutics, 2018
Background: Bacillus Calmette-Guérin (BCG) vaccination may have beneficial non-specific effects on child survival, the effects being stronger for children developing a scar. In a prospective cohort study, we examined determinants for not developing a BCG

Neonatal Immunization: Rationale, Current State, and Future Prospects

open access: yesFrontiers in Immunology, 2018
Infections take their greatest toll in early life necessitating robust approaches to protect the very young. Here, we review the rationale, current state, and future research directions for one such approach: neonatal immunization. Challenges to neonatal

How to evaluate potential non-specific effects of vaccines: the quest for randomized trials or time for triangulation?

open access: yesExpert Review of Vaccines, 2018
Introduction: Emerging evidence suggests that vaccines, in addition to their disease-specific effects, have important non-specific effects (NSEs), which contribute to their overall effect on mortality and morbidity.

Epidemiological studies of the ‘non‐specific effects’ of vaccines: I – data collection in observational studies

open access: yesTropical Medicine & International Health, 2009
SummaryRoutine vaccination programmes have led to substantial declines in the incidence of most of the target diseases. In these circumstances, vaccine effects beyond those on the target diseases may become evident. Several studies have suggested that certain vaccines may influence mortality in low income settings in ways that cannot be attributed to ...

Choice and Design of Adjuvants for Parenteral and Mucosal Vaccines

open access: yesVaccines, 2015
The existence of pathogens that escape recognition by specific vaccines, the need to improve existing vaccines and the increased availability of therapeutic (non-infectious disease) vaccines necessitate the rational development of novel vaccine concepts ...

Distinct Adverse Reactions to mRNA, Inactivated Virus, and Adenovirus Vector COVID-19 Vaccines: Insights from a Cohort Study on Atopic and Non-Atopic Subjects in Brazil

open access: yesVaccines
The emergence of COVID-19 caused by SARS-CoV-2 prompted an unprecedented global response to develop vaccines at an accelerated pace. Messenger RNA (mRNA) and adenovirus vector vaccines emerged as the frontrunners in global immunization efforts ...
