Preferences for vaccines against children's diarrheal illness among mothers in Poland and Hungary.

Purpose: Although the World Health Organization recommends universal rotavirus immunization, uptake of the vaccine is low in Poland and Hungary, where it is not covered by the National Immunization Program. This study aimed to quantify mothers' preferences for vaccines preventing children's diarrheal illness and to examine whether willingness to vaccinate varies with working status.

Methods: Mothers of children aged <3 years living in Poland and Hungary completed an online discrete-choice experiment survey.

Incidence of acute otitis media in children below 6 years of age seen in medical practices in five East European countries.

Background: Although acute otitis media (AOM) remains a major public health problem worldwide and brings economic burden on health care system and caregivers, little information is available about its epidemiology in Eastern Europe.

Methods: We conducted an epidemiological, prospective, observational, multi-centre cohort study (NCT01365390) in five East European countries (Estonia, Lithuania, Poland, Romania and Slovenia) between June 2011 and January 2013 to determine the incidence and clinical characteristics of AOM among children aged < 6 years during 1 year.

Results: AOM incidence was 160.

[Adverse events following BCG vaccination in infants and children up to 36 months of age].

The aim of the study is to evaluate frequency, treatment and clinical type of adverse reaction (AEFI) after BCG vaccination. Between January 2003 and December 2006, 64 children with AEFI after BCG vaccination were registered in the Pediatric Vaccination Centre in Lódź. Different types of AEFI were distinguished on the basis of Lotte's classification (1977).

[Does vaccination protect a child of an HBs Ag carrier mother against HBV infection?].

The aim of the study was to determine the degree of protection provided to the children born from HBs antigen carrying mothers, by vaccination administered according to the 0-1-2-12 scheme (Engerix B, SmithKline Beecham) as well as the level of HBs antibodies after a booster dose given 5 years later. The examination was conducted in 52 children. The level of HBs antibodies as well as the remaining serological markers of HBV infection were assessed at the age of 6.
