Background
The Expanded Programme on Immunisation (EPI) has increased the number of antigens and injections administered at one visit. There are concerns that more injections at a single...
To inform epidemic response strategies for the African meningitis belt after a meningococcal serogroup A conjugate vaccine was introduced in 2010, the researchers compared the effectiveness and...
Multiple cornerstones have shaped the history of vaccines, which may contain live-attenuated viruses, inactivated organisms/viruses, inactivated toxins, or merely segments of the pathogen that could...
Background: Within Pakistan, estimates of vaccination coverage with the pentavalent vaccine, oral polio vaccine (OPV) and measles vaccine (MV) in 2011 were reported to be 74%, 75% and 53%,...
BACKGROUND:
Considering the current polio situation Pakistan needs vaccine combinations to reach maximum population level immunity. The trial assessed whether inactivated poliovirus vaccine (IPV)...
Active symptom surveillance was applied to three selected communities ( 160 147 persons) in Tianjin from 2010 to 2012. The researchers examined 1089 individuals showing pertussis-like symptoms, of...
Hepatitis B virus (HBV) vaccination has been part of the Expanded Programme of Immunization (EPI) in Tunisia since 1995. The aim of this study was to evaluate, for the first time, the impact of mass...
BACKGROUND:
Children under the age of 12 months may receive an early dose of measles-mumps-rubella (MMR) vaccine to provide short-term protection in the case of a disease outbreak. Following a...
Newborn Vaccination is identified as a critical parameter for evaluating the overall performance of immunization programs with guidelines clearly advocating for administration of BCG, OPV zero dose...
Despite the widespread availability of 2 classes of effective vaccines, whole cell and acellular, Bordetella pertussis infection remains a global epidemic. Pertussis is primarily a disease of...
Pertussis remains a major cause of morbidity and mortality, particularly in infants and young children, and despite the availability of vaccines and pertinent national and international guidelines....
BACKGROUND:
Introduction of new vaccines in low- and lower middle-income countries has accelerated since Gavi, the Vaccine Alliance was established in 2000. This study sought to (i) estimate the...
After the introduction of rotavirus vaccination for infants, significant declines for three full years were observed in under-5-y diarrhea-related mortality and hospital admissions for diarrhea in...
In 2006, Brazil began routine immunization of infants <15 wk of age with a single-strain rotavirus vaccine. The researchers evaluated whether the rotavirus vaccination program was associated with...
The Gambian PCV programme reduced the incidence of invasive pneumococcal disease in children aged 2–59 months by around 55%. Further surveillance is needed to ascertain the maximum effect of the...
BACKGROUND: Rates of invasive pneumococcal disease have declined since widespread introduction of pneumococcal conjugate vaccines (PCVs) in the United States. We evaluated the impact of immunization...
OBJECTIVE: To analyze the characteristics of pneumococcal meningitis in children ≤ 14 years old following the market introduction of pneumococcal conjugate vaccines in our community. METHODS:...
