Case Reports
Bone erosion and subacromial bursitis caused by diphtheria-tetanus-poliomyelitis vaccine.
Revaxis(®) is a vaccine against diphtheria, tetanus and poliomyelitis (dT-IPV). This vaccine should not be administered by the intradermal or intravenous route. Poor injection techniques and related consequences are rare. ⋯ Outcome was favourable after intra-articular corticosteroids. Reports of articular or periarticular injury after vaccination are extremely rare, in view of the substantial number of vaccines administered every year. The potential complications of vaccination are well known to general practitioners but under-reported in the literature.

Changes in serotype distribution have been induced after pneumococcal conjugate vaccines (PCV) implementation, and non-vaccine serotypes are now circulating. Among these latter serotypes, we aimed to distinguish those with high invasive disease potential before (2008-2009) and after PCV13 implementation (2012-2013). ⋯ In children <2 years old, compared to the previous period, the number of serotypes having a high disease potential decreased after PCV13 implementation, only two non-vaccine serotypes, 24F and 12F, had high invasive disease potential.

In addition to improved sanitation, hygiene, and better access to safe water, oral cholera vaccines can help to control the spread of cholera in the short term. However, there is currently no systematic method for determining the best allocation of oral cholera vaccines to minimize disease incidence in a population where the disease is endemic and resources are limited. We present a mathematical model for optimally allocating vaccines in a region under varying levels of demographic and incidence data availability. ⋯ Results indicate that, given appropriate surveillance data, targeting age groups and regions with the highest disease incidence should be the first priority, followed by other groups primarily in order of disease incidence, as this approach is the most life-saving and cost-effective. A lack of detailed incidence data results in distribution strategies which are not cost-effective and can lead to thousands more deaths from the disease. The mathematical model allows for what-if analysis for various vaccine distribution strategies by providing the ability to easily vary parameters such as numbers and sizes of regions and age groups, risk levels, vaccine price, vaccine efficacy, production capacity and budget.

The purpose of this study was to determine the risk of aseptic meningitis after mumps vaccination in younger children compared with older children. ⋯ The first dose of mumps vaccine that is currently available for use in Japan may be administered in children less than 3 years of age in order to complicate a less aseptic meningitis after immunization.

Randomized Controlled Trial
Text message reminders for timely routine MMR vaccination: A randomized controlled trial.
Measles-mumps-rubella (MMR) vaccination is important for preventing disease outbreaks, yet pockets of under-vaccination persist. Text message reminders have been employed successfully for other pediatric vaccines, but studies examining their use for MMR vaccination are limited. This study assessed the impact of text message reminders on timely MMR vaccination. ⋯ Text message reminders improved timely MMR vaccination of high-risk children without a baseline one-year visit.
