[Characterization of hypotonia-hyporesponsiveness after pentavalent vaccine and neurodevelopmental screening in children under 6 years of age, 2013-2018, Uruguay].

Background: Hypotonic-hyporesponsive episodes (HHE) is one frequently reported neurologic adverse effect supposedly attributable to vaccination and immunization. Its long-term impact on neurodevelopment is not completely known.

Aim: To characterize the post-pentavalent vaccine HHE events reported to the Uruguayan Ministry of Health (M of H) between 2014 and 2018.

[Active surveillance of febrile seizures associated to DPT vaccines in a sentinel hospital in Uruguay].

Background: Febrile seizures are VAERS often associated with whole-cells Diphtheria-Pertussis-Tetanus vaccines.

Aim: To analyze the association of febrile seizures with the administration of pentavalent vaccine in children under two-years-old assisted in the Centro Hospitalario Pereira Rossell (CHPR), in Montevideo during 2014.

Methods: Self-controlled case series study.

Pneumococcal Meningitis Before and After Universal Vaccination With Pneumococcal Conjugate Vaccines 7/13, Impact on Pediatric Hospitalization in Public and Nonpublic Institutions, in Uruguay.

This is the first study showing the impact of 13-valent pneumococcal conjugate vaccine on pneumococcal meningitis in Latin America; a significant (63.5%) reduction in hospitalization was observed during the first 6 years after starting vaccination. A 90% reduction of pneumococcal conjugate vaccines 7/13 serotypes was observed (P < 0.

Effectiveness of the 7-valent pneumococcal conjugate vaccine against vaccine-type invasive disease among children in Uruguay: an evaluation using existing data.

The 7-valent pneumococcal conjugate vaccine (PCV7) was introduced into the routine immunization program in Uruguay in March 2008 with a 2-dose primary series (given at 2 and 4 months) plus a booster (at 12 months) and a catch-up campaign (two doses given at 15 and 17 months). We used a case-control methodology and existing laboratory surveillance and immunization registry data from Uruguay to evaluate PCV7 effectiveness against vaccine-type invasive pneumococcal disease (VT-IPD). Cases of VT-IPD (with pneumococcus obtained from a normally sterile site) were identified through the National Reference Laboratory.

Impact of vaccination against Haemophilus influenzae type b with and without a booster dose on meningitis in four South American countries.

To inform World Health Organization recommendations regarding use of Haemophilus influenzae type b (Hib) vaccines in national immunization programs, a multi-country evaluation of trends in Hib meningitis incidence and prevalence of nasopharyngeal Hib carriage was conducted in four South American countries using either a primary, three-dose immunization schedule without a booster dose or with a booster dose in the second year of life. Surveillance data suggest that high coverage of Hib conjugate vaccine sustained low incidence of Hib meningitis and low prevalence of Hib carriage whether or not a booster dose was used.
