An 8-Year Prospective, Observational, Multi-centre Post-Marketing Safety Surveillance Study Conducted in South Korea (2014-2022) Following the Introduction of GSK's Inactivated Quadrivalent Seasonal Influenza Vaccine (Fluarix Tetra) for Subjects Aged 6 Months and Older.

Introduction: Seasonal influenza is associated with substantial public health burden. The objective of this study was to assess the safety of inactivated quadrivalent seasonal influenza vaccine (IIV4, Fluarix Tetra, GSK, Belgium) in subjects aged ≥ 6 months in Korea.

Methods: This prospective, observational, non-comparative, multi-centre post-marketing surveillance study was conducted in Korea in subjects aged ≥ 3 years for 6 years (2014-2020) and extended to subjects aged 6-35 months for 4 years (2018-2022).

Respiratory Syncytial Virus Disease Burden in Community-Dwelling and Long-Term Care Facility Older Adults in Europe and the United States: A Prospective Study.

Background: Data on respiratory syncytial virus (RSV) disease burden in adults remain scarce. We assessed the burden of confirmed RSV-acute respiratory infections (cRSV-ARIs) in community-dwelling (CD) adults and those in long-term care facilities (LTCFs).

Methods: In this prospective cohort study covering 2 RSV seasons (October 2019-March 2020 and October 2020-June 2021), RSV-ARIs were identified through active surveillance, in medically stable CD-adults ≥50 years (Europe) or adults ≥65 years in LTCFs (Europe and the United States).

Pneumonia hospitalizations of children aged <2 years in Poland before (2013-2016) and after (2017-2018) universal mass vaccination with 10-valent pneumococcal non-typeable protein D conjugate vaccine.

As infection with is an important cause of pneumonia in children, the World Health Organization recommends childhood pneumococcal conjugate vaccines (PCVs). In January 2017, PCV universal mass vaccination (UMV) was introduced in Poland for children aged <2 years. The objective of this study was to estimate and describe the trends in the incidences of various types of pneumonia hospitalizations in Poland before (2013-2016) and after (2017-2018) introduction of the UMV program.

Respiratory syncytial virus acute respiratory infections in ≥ 65-year-old adults in long-term care facilities in the Czech Republic.

Objectives: Due to immunosenescence and presence of comorbidities, respiratory syncytial virus (RSV) disease burden is a major health concern in older adults, which is expected to increase with the life expectancy rise. Data on RSV burden are scarce in older adults residing in long-term care facilities, a vulnerable population living in crowded settings. Therefore, two independent prospective studies were conducted during the 2003-2004 and 2004-2005 RSV seasons to assess RSV acute respiratory illnesses (ARIs) and lower respiratory tract infections (LRTIs) in ≥ 65-year-old adults residing in long-term care facilities in the Czech Republic.

Therefore, epidemiological surveillance is critical for monitoring their circulation pattern. Trivalent and quadrivalent vaccine formulations are available in Panama (until and since 2016, respectively).

Incidence and mortality of pertussis disease in infants <12 months of age following introduction of pertussis maternal universal mass vaccination in Bogotá, Colombia.

Background: Maternal immunization with tetanus, diphtheria, and acellular pertussis (Tdap) vaccine confers protection to young infants. We aimed to describe trends in pertussis incidence and associated mortality in children aged <12 months before and after introduction of maternal Tdap immunization in Bogotá, Colombia.

Methods: Data on pertussis-related cases/deaths in infants aged <12 months were collected from SIVIGILA for the period 2005-2016, and compared incidence for the pre-vaccine introduction (2005-2012) and post-maternal Tdap vaccination (2014-2016) periods in infants aged <12 months and in three distinct age-strata; ≤6 weeks, 7-<28 weeks, and 28-52 weeks.

Trends in all-cause pneumonia and otitis media in children aged <2 years following pneumococcal conjugate vaccine introduction in Colombia.

In Colombia, pneumococcal conjugate vaccines (PCVs) were implemented into the infant universal mass vaccination program in a stepwise manner; PCV-7 between 2009 and 2011 in different geographic regions/cities, with nationwide introduction of a 10-valent vaccine (PHiD-CV) in 2012. We aimed to describe trends in all-cause pneumonia mortality and overall mortality, and in the incidence of all-cause pneumonia and otitis media (OM) in Colombian children <2 y (y = years) of age, before and after PCV introduction. We obtained mortality and incidence data, nationally and for five major cities (Bogota, Medellin, Barranquilla, Cali and Cartagena) from 2005-2016 and 2008-2016, respectively, comparing mortality and incidence proportions in the post-PCV introduction period with those in the pre-PCV period.

A 6-year Prospective, Observational, Multi-Center Post-Marketing Surveillance of the Safety of Tetanus Toxoid, Reduced Diphtheria Toxoid, and Acellular Pertussis (Tdap) Vaccine in Korea.

Background: Incidence of whooping cough is increasing in Korea. Since 2011, occurrence among adolescents and adults has risen putting vulnerable neonates at risk. National immunization guidelines now include Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccination during pregnancy and as a cocooning strategy (i.

Post-marketing surveillance to assess the safety and tolerability of a combined diphtheria, tetanus, acellular pertussis and inactivated poliovirus vaccine (DTaP-IPV) in Korean children.

Infanrix-IPV (GSK, Belgium) is a diphtheria, tetanus, acellular pertussis, and inactivated poliovirus combination vaccine (DTaP-IPV) licensed in many countries including Korea. In accordance with Korean regulations, we conducted a post-marketing surveillance (PMS) to evaluate the safety of DTaP-IPV administered to Korean children in routine immunization schedules. Children aged <7 years receiving at least one dose of DTaP-IPV either as part of a primary (3-dose) vaccination series or as a subsequent booster were enrolled.

A 6-year safety surveillance of 10-valent pneumococcal non-typeable protein D conjugate vaccine (PHiD-CV) in South Korea.

In 2010, Korea introduced 10-valent pneumococcal conjugate vaccine for children aged 6 weeks to 5 years against invasive disease caused by serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F, 23F and cross-reactive 19A. The aim of this 6-year real-world study of 646 healthy Korean children from 16 centers vaccinated in routine practice is to monitor vaccine safety, as per Ministry of Food and Drug Safety regulations. Around 50% had a past or existing medical condition, 19.

[Bacterial etiology of acute otitis media in Spain in the post-pneumococcal conjugate vaccine era].

Introduction: Acute otitis media (AOM) is common in children aged <3 years. A pneumococcal conjugate vaccine (PCV) (PCV7; Prevenar, Pfizer/Wyeth, USA) has been available in Spain since 2001, which has a coverage rate of 50-60% in children aged <5 years.

Materials And Methods: Children aged ≥3 to 36 months with AOM confirmed by an ear-nose-throat specialist were enrolled at seven centers in Spain (February 2009-May 2012) (GSK study identifier: 111425).

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.
