BACKGROUND Increasing the number of vaccine doses may potentially improve overall efficacy. Decision-makers need information about choosing the most efficient dose schedule to maximise the total health gain of a population when operating under a constrained budget. The objective of this study is to identify the most efficient vaccine dosing schedule within a fixed vaccination budget from a heal...
The need to keep vaccines cold in the face of high ambient temperatures and unreliable access to electricity is a challenge that limits vaccine coverage in low and middle-income countries (LMICs). Greater vaccine thermostability is generally touted as the obvious solution. Despite conventional wisdom, comprehensive analysis of the value proposition for increasing vaccine thermostability has bee...
Effective polysaccharide(conjugate) vaccines against Neisseria meningitidis serogroups A, C, W, and Y have been widely used, but serogroup B meningococci remain a major cause of severe invasive meningococcal disease (IMD) worldwide, especially in infants. Recently, a vaccine, 4CMenB (Bexsero(®)), containing three recombinant proteins, and outer membrane vesicles (OMV) derived from a serogroup B...
Routine administration of the quadrivalent human papillomavirus (HPV) vaccine has been recommended for 11-12-year-old males since 2011, but coverage remains low. In a U.S. national sample of parents of 11-17-year-old males (n=779), 78.6% of parents reported their sons had not received the HPV vaccine. The most common reason for non-vaccination (56.7%) was "My doctor or healthcare provider has n...
OBJECTIVE Measles outbreaks are infrequent and localized in areas with high coverage of measles vaccine. The need is to assess long-term effectiveness of coverage. Since 1991, no measles epidemic affecting the whole island has occurred in Taiwan, China. Epidemiological models are developed to predict the long-term measles antibody profiles and compare the merits of different immunization polici...
BACKGROUND In 2014 a 2-doses varicella vaccine (VarV) schedule was recommended by the Zhejiang Provincial Center for Disease Control and Prevention. We aimed to assess the coverage of the 1st dose of VarV (VarV₁) and the 2nd dose of VarV (VarV₂) among children aged 2-6 years through the Zhejiang Provincial Immunization Information System (ZJIIS) and to explore the determinants associated with t...
Measles vaccine was introduced in Gipuzkoa (Basque country, Spain) in 1978 and was replaced by the measles, mumps, and rubella (MMR) vaccine for children aged 12-15 months in 1981. A second dose of the MMR vaccine was introduced in 1992. Both doses of the MMR vaccine were well accepted by the population and high coverage was achieved (95% and 91% for the first and second doses respectively for ...
With the introduction of vaccines, mortality and morbidity among children have significantly reduced. While a good proportion population accepts vaccine, still gap remains in immunisation coverage India. A growing number people are delaying or refusing vaccines. This phenomenon is called “vaccine hesitancy.” In spite tremendous effort to develop an effective COVID 19 major deterrent for same va...
In 2001, a publicly funded 7 valent pneumococcal conjugate vaccine (7vPCV) program commenced for Aboriginal and Torres Strait Islander children aged less than 2 years. This study updates early estimates of 7vPCV coverage in Aboriginal and Torres Strait Islander children using Australian Childhood Immunisation Register data between 31 December 2004 and 30 September 2007. We chose four 3-month bi...
Romania has the highest cervical cancer burden in Europe. Despite the implementation of two human papillomavirus (HPV) vaccination programmes, the uptake remained extremely low and the programmes were discontinued. Given that media are a common source of information for the public and may influence vaccination decisions, this article sought to explore the content and quality of HPV vaccine medi...
