[Current events in vaccination]. / Actualités en matière de vaccination.

The annual meeting of the Infectious Disease Society of America (IDSA) ; which brought together nearly 5000 participants from over 80 countries in Vancouver, Canada, October 21 to 24, 2010 ; provided a review of the influenza (H1N1) 2009 pandemic, evaluated vaccination programmes and presented new vaccines under development. With 12,500 deaths in the United States in 2009-2010, the influenza (H1N1) 2009 pandemic was actually less deadly than the seasonal flu. But it essentially hit the young, and the toll calculated in years of life lost is high. The monovalent vaccines, whether live attenuated or inactivated with or without adjuvants, were well tolerated in toddlers, children, adults and pregnant women. In order to protect infants against pertussis, family members are urged to get their booster shots. The introduction of the 13-valent Pneumococcal conjugated vaccine in the beginning of 2010 may solve - but for how long ? - the problem of serotype replacement, responsible for the re-increasing incidence of invasive Pneumococcal infections observed in countries that had introduced the 7-valent vaccine. The efficacy of a rotavirus vaccine has been confirmed, with a reduction in hospitalization in the United States and a reduction in gastroenteritis-related deaths in Mexico. In the United States, vaccination of pre-adolescents against human papillomavirus (HPV) has not resulted in any specific undesirable effects. Routine vaccination against chicken pox, recommended since 1995, has not had an impact on the evolution of the incidence of shingles. Vaccination against shingles, recommended in the United States for subjects 60 years and over, shows an effectiveness of 55 %, according to a cohort study (Kaiser Permanente, Southern California). Although some propose the development of personalized vaccines according to individual genetic characteristics, the priority remains with increasing vaccine coverage, not only in infants but also in adults and the elderly. Vaccine calendars that cover a whole lifetime should be promoted, since the vaccination of adults and seniors is a determining factor of good health at all ages.

[Influenza vaccination coverage in asthmatic children in France in 2006-2007]. / Couverture vaccinale contre la grippe chez les enfants asthmatiques en France en 2006-2007.

In France, an annual seasonal influenza vaccination has been recommended since 2000 for patients suffering from chronic respiratory diseases, including asthma. Each year, a free influenza vaccination voucher is sent by the French Public Health Insurance authorities to patients with chronic respiratory disease, including severe asthma. In November 2006, this measure was extended to all asthmatic patients, irrespective of asthma severity. The present paper examines the 2006-2007 influenza vaccination coverage rate in 433 asthmatic children aged six to 17 years (mean age: 9.5 years; male: 61%) who consulted a pediatric pulmonologist between March and September 2007 in eight hospitals throughout France. The influenza vaccination coverage rate was 15.7% for the 2006-2007 season (13.9% for the 2005-2006 season and 10.9% for the 2004-2005 season). General practitioners vaccinated 72.1% of the children. Lack of information (42%) was the most frequently reported reason for non-vaccination. Free vouchers (received by 39.6% of the children) significantly increased the vaccination coverage rate (31% versus 5.9%; p < 0.001). In France, in 2006-2007, the influenza vaccination coverage rate in asthmatic children was far below the national public health objective to achieve for the year 2008 (at least 75%). Concerted action is needed to improve the influenza vaccination coverage rate in asthmatic children.

Low influenza vaccination coverage in asthmatic children in France in 2006-7.

In France, annual seasonal influenza vaccination has been recommended since 2000 for patients suffering from chronic respiratory diseases, including asthma. Since 1988, each year from September to December, a free influenza vaccination voucher is sent by the French Public Health Insurance authorities to patients with chronic respiratory disease, including severe asthma. In November 2006, this measure was extended to all asthmatic patients, irrespective of asthma severity. The present paper examines the 2006-7 influenza vaccination coverage rate (VCR) in 433 asthmatic children aged 6 to 17 years (mean age: 9.5 years; male: 61%) who consulted a paediatric pulmonologist between March and September 2007 in eight hospitals throughout France. The influenza VCR was 15.7% for the 2006-7 season (13.9% for the 2005-6 season and 10.9% for the 2004-5 season). General practitioners vaccinated 72.1% of the children. "Lack of information" (42%) was the most frequently reported reason for non-vaccination. Vouchers (received by 39.6% of the children) significantly increased the VCR (31% versus 5.9%; p<0.001). In France, in 2006-7, the influenza VCR in asthmatic children was far below the national public health objective (at least 75% for the year 2008). Concerted action is needed to improve the influenza VCR in asthmatic children.

[Evaluation of uterine activity by ambulatory tocography]. / Evaluation de l'activité utérine par tocographie ambulatoire.

The mother's sensations of uterine contractions were compared to the graphs made by the ambulatory tocograph linked to a telephone system (system Tokos), 95 women were assessed. They felt only 20% of their contractions. When the pregnancies were single pregnancies the sensation was found in more women (26%). In a group of women who had a threat of premature labor only 12% of contractions were felt.

[Ambulatory monitoring and telephone transmission of uterine activity. Preliminary study on the evaluation of the TOKOS system]. / Monitorage ambulatoire et transmission téléphonique de l'activité utérine. Etude préliminaire sur l'évaluation du système TOKOS.

The authors compare 100 tracings of uterine contractions, recorded using a mobile monitoring apparatus with telephone output TOKOS System), with 100 tracings recorded using static equipment. The TOKOS system is useful in diagnosis of uterine contraction, being equivalent to the reference system. The TOKOS system is superior to the reference system in that it allows the intensity of the contractions to be evaluated. The TOKOS system is an original approach to maternal perception of uterine activity. Overall, 28% of contractions are identified by the patient. The authors conclude that the tracings produced by the TOKOS system are more reliable than maternal perception of uterine contractions.
