ABSTRACT Introduction: The COVID-19 pandemic produced a health crisis affecting countries' vaccination coverage statistics. Objective: To describe the coverage of recommended vaccines during the pre-pandemic (2015-2019) and pandemic (2020-2021) periods in Paraguay. Materials and Methods: This was a descriptive, observational cross-sectional study, comprising children from 0 to 5 years of age, from the Country's 18 Health Regions. The vaccination coverage of the National Expanded Immunization Program, pre-pandemic (2015-2019) and pandemic (2020-201) periods were analyzed. The recommended vaccinations included were: BCG, DTP1, DTP3, IPV1 and bOPV3, MMR1, MMR2 and yellow fever vaccine (AA), the calculation of vaccination coverage at the country level was carried out through the analysis of the weekly electronic report of doses of vaccines administered by Health Region. The comparison of vaccination coverage by recommended vaccine was established, by periods and age range. Results: During the pandemic, a decrease in vaccination coverage of the recommended vaccines was observed, for BCG: 4% (2020), 15% (2021); DTP1: 5% (2020), 13% (2021); DTP3: 9% (2020), 22% (2021); IPV1: 5% (2020), 16% (2021); bOPV3: 7% (2020), 19% (2021); MMR1: 9%, MMR2: 13% (2020), MMR1: 17%, MMR2: 16% (2021) and AA: 7% (2020), 15% (2021). Conclusion: During the Covid-19 pandemic, vaccination coverage of all recommended vaccines decreased, a similar decrease was found in other countries in the Americas, there is a risk of outbreaks of vaccine-preventable diseases due to the accumulation of susceptible populations.
ABSTRACT
Introducción: la vacunación antigripal es la forma más eficaz para prevenir la enfermedad por virus Influenza y sus complicaciones. La cobertura en los profesionales sanitarios es un indicador de calidad hospitalaria. Material y métodos: estudio descriptivo de corte transversal. A partir de registros vacunales, se calculó la cobertura para las campañas 2013 a 2018. Se compararon las coberturas por trienios. Se describieron características generales de las campañas de 2016 a 2018. Resultados: en 2016 se alcanzó la mayor tasa del período (59,79%, IC 95%:58,75-60,81); en 2017, la menor (34,46%, IC 95%:33,48-35,46). La campaña 2018 obtuvo una cobertura de 54,90% (IC 95%: 53,88-55,92) y se inició más tempranamente que otras. Al comparar las tasas trienales del período se observó una diferencia de proporción de -1,3% (IC 95%: -2.84-0.24). Durante los tres últimos años, el personal vacunado correspondió mayormente al sexo femenino, a la Sede Central y tenía relación contractual directa. Las mayores coberturas específicas correspondieron a la sede de San Justo y a los profesionales de enfermería. El puesto ambulante fue el que aplicó más vacunas. Conclusión: si bien hubo variaciones en las coberturas alcanzadas a lo largo de los años, siendo la del año 2016 la más elevada y la del año 2017 la más baja, no se observaron diferencias estadísticamente significativas en las coberturas alcanzadas al comparar trienios. Resulta necesario continuar realizando intervenciones adaptadas al contexto local que permitan alcanzar los objetivos de cobertura esperados. Discusión: se reconocieron varios obstáculos para alcanzar las coberturas esperadas. La educación al personal de salud, la evaluación sistematizada de los ESAVI (Eventos supuestamente atribuibles a vacunación e inmunización) y la descripción de los elementos que facilitaron las coberturas específicas elevadas de algunas subpoblaciones podrían contribuir para mejorar los resultados.

Introduction: influenza vaccination is the most effective way to prevent influenza virus disease and its complications. Coverage in health professionals measurement is an indicator of hospital quality. Material and methods: descriptive cross-sectional study. From vaccination records, the coverage was calculated for the 2013 to 2018 campaigns. The coverage for three years was compared. General characteristics of the campaigns from 2016 to 2018 were described. Results: in 2016, the highest was achieved during the period (59.79%, IC 95%: 58.75 -60.81). In 2017, the lowest (34.46%, IC 95%: 33.48-35,46). The 2018 campaign achieved a coverage of 54.90% (IC 95%: 53.88-55.92) and started earlier than others. When comparing the triennial rates of the period, a difference of proportion of -1.3% was observed (IC 95%: -2.84-0.24). During the last three years, the vaccinated staff corresponded mostly to the female sex, to the headquarters and had a direct contractual relationship. The largest specific coverage corresponded to the San Justo headquarters and to nursing professionals. The ambulatory position was the post that applied the most vaccines. Conclusion: although there were variations in the coverage achieved over the years, with 2016 being the highest and 2017 being the lowest, there were no statistically significant differences in the coverage achieved when comparing trienniums. It is necessary to continue carrying out interventions adapted to the local context to achieve the expected coverage objectives. Discussion: several obstacles were recognized to reach the expected coverage. The education of health personnel, the systematic evaluation of the ESAVIs and the description of the elements that facilitated the high specific coverage of some subpopulations could contribute to improve the results.

A Hepatite B é uma infecção viral que se destaca pela alta morbimortalidade, cronicidade, cirrose e carcinoma hepatocelular. Esta pesquisa objetivou avaliar a situação sorológica e vacinal para Hepatite B em puérperas internadas em uma maternidade pública de Teresina. Trata-se de um estudo transversal, realizado por meio de entrevistas com 377 puérperas, entre janeiro a fevereiro de 2011. A baixa cobertura vacinal caracterizou-se pelas oportunidades perdidas de vacinação, pois 77,5% delas não receberam nenhuma dose da vacina, embora a maioria tenha realizado o pré-natal. Apenas 41,9% realizaram sorologia. Em relação às informações sobre a vacina, observa-se que 77,3% das puérperas foram informadas sobre as vacinas que deveriam receber durante o pré-natal. Dentre as fontes informantes, o enfermeiro foi o mais citado, com 55%, reforçando o seu papel de destaque como um educador em saúde na atenção pré-natal. Evidenciou-se a ocorrência de baixas coberturas sorológica e vacinal, denunciando a ineficiência do acompanhamento pré-natal.
Hepatitis B is a viral infection notable for high rates of morbidity, chronicity, cirrhosis and hepatocellular carcinoma (HCC). This transversal study to evaluate serologic and Hepatitis B vaccination status in women admitted to a public maternity hospital in Teresina was conducted in January and February, 2011, through interviews of a sample of 377 postpartum women. Poor vaccine coverage was characterized by missed opportunities for immunization: 77.5% of the sample received no dose of the vaccine, even though most had received antenatal care. Hepatitis serology testing had been performed on only 41.9%. However, 77.1% were informed of what vaccines they should receive during the antenatal period. Nurses were the information source most mentioned (by 55%), underlining their key role as health educators in antenatal care. The study found low vaccine and serological coverage, evidencing the inefficiency of antenatal monitoring.

Esta investigación tuvo como objetivo evaluar la situación serológica y vacunal contra la Hepatitis B en mujeres en el periodo de posparto internadas en una maternidad pública de Teresina. Se trata de un estudio transversal, realizado a través de entrevistas junto a 377 mujeres en el posparto, entre enero y febrero de 2011. La baja cobertura vacunal se ha caracterizado por las oportunidades perdidas de vacunación, ya que el 77,5% no recibió ninguna dosis de vacuna, aunque la mayoría haya realizado el prenatal. Sólo el 41,9% realizó serología. En cuanto a las informaciones acerca de la vacuna, se observa que el 77,1 % de las mujeres en posparto fue informado acerca de las vacunas que se deben tomar en el período prenatal. Entre las fuentes informantes, el enfermero fue el que más se ha mencionado, en 55%, lo que refuerza su papel de destaque como un educador de salud en la atención prenatal. Reveló la existencia de bajas coberturas serológicas y vacunal, denunciando la ineficiencia de la atención prenatal.

OBJECTIVE: To develop a model to assess different strategies of pertussis booster vaccination in the city of São Paulo. METHODS: A dynamic stationary age-dependent compartmental model with waning immunity was developed. The "Who Acquires Infection from Whom" matrix was used to modeling age-dependent transmission rates. There were tested different strategies including vaccine boosters to the current vaccination schedule and three of them were reported: (i) 35 percent coverage at age 12, or (ii) 70 percent coverage at age 12, and (iii) 35 percent coverage at age 12 and 70 percent coverage at age 20 at the same time. RESULTS: The strategy (i) achieved a 59 percent reduction of pertussis occurrence and a 53 percent reduction in infants while strategy (ii) produced 76 percent and 63 percent reduction and strategy (iii) 62 percent and 54 percent, respectively. CONCLUSION: Pertussis booster vaccination at age 12 proved to be the best strategy among those tested in this study as it achieves the highest overall reduction and the greatest impact among infants who are more susceptible to pertussis complications.
OBJETIVO: Desenvolver um modelo capaz de acessar resultados de diferentes possíveis estratégias de reforço vacinal contra a coqueluche, na cidade de São Paulo. MÉTODOS: O modelo matemático dinâmico proposto é dependente da idade e considerou perda da imunidade vacinal com o avanço da idade. A matriz "who acquire infection from whom" foi utilizada para inserir as diferentes dinâmicas de contatos entre os grupos etários. Diferentes estratégias vacinais foram testadas, acrescentando reforços vacinais ao atual esquema utilizado, e três diferentes estratégias foram reportadas: (i) 35 por cento ou (ii) 70 por cento de cobertura vacinal na idade de 12 anos e (iii) coberturas vacinais de 35 por cento aos 12 anos e 70 por cento aos 20 anos ao mesmo tempo. RESULTADOS: A estratégia (i) produziu redução de 59 por cento nos casos de coqueluche e 53 por cento de redução entre os menores de um ano; a estratégia (ii) alcançou redução de 76 por cento nos casos e de 63 por cento entre os menores de um ano; a estratégia (iii) reduziu em 62 por cento o total de casos e 54 por cento entre os menores de um ano. DISCUSSÃO: Reforço vacinal contra a coqueluche aos 12 anos é a melhor estratégia dentre as testadas, pois gera maior redução de casos em todas as idades e alcança maior impacto entre os menores de um ano, os mais vulneráveis às complicações da coqueluche.
OBJETIVO: Desarrollar un modelo capaz de acceder resultados de diferentes posibles estrategias de refuerzo vacunal contra la tosferina, en la ciudad de Sao Paulo, Sureste de Brasil. MÉTODOS: El modelo matemático dinámico propuesto es dependiente de la edad y consideró pérdida de la inmunidad vacunal con el avance de la edad. La matriz "who acquire infection from whom" fue utilizada para insertar las diferentes dinámicas de contactos entre los grupos de edad. Diferentes estrategias vacunales fueron evaluadas, añadiendo refuerzos vacunales al actual esquema utilizado, e tres diferentes estrategias fueron reportadas: (i) 35 por ciento o (ii) 70 por ciento de cobertura vacunal en la edad de 12 años e (iii) coberturas vacunales de 35 por ciento a los 12 años y 70 por ciento a los 20 años al mismo tiempo. RESULTADOS: La estrategia (i) produjo reducción de 59 por ciento en los casos de tosferina y 53 por ciento de reducción entre los menores de un año; la estrategia (ii) alcanzó reducción de 76 por ciento en los casos y de 63 por ciento entre los menores de un año; la estrategia (iii) redujo en 62 por ciento el total de casos y 54 por ciento entre los menores de un año. DISCUSIÓN: Refuerzo vacunal contra la tosferina a los 12 años es la mejor estrategia entre las evaluadas, pues genera mayor reducción de casos en todas las edades y alcanza mayor impacto entre los menores de un año, los mas vulnerables a las complicaciones de la tosferina.

Introducción: la enfermedad meningocócica constituye un importante problema de salud mundial. Desde 1991 la vacuna VA-MENGOC-BC® se aplica en Cuba a los niños menores de 1 año. Objetivo: evaluar la efectividad de la vacuna VA-MENGOC-BC®. Métodos: para la evaluación poslicenciamiento de VA-MENGOC-BC® se estudiaron los lactantes con enfermedad meningocócica notificados entre 1997 y 2008. Resultados: ocurrieron 114 casos para una incidencia media anual de 7,1/100 000 lactantes. La estimación de la efectividad vacunal media resultó de 84,0 por ciento, oscilando entre 68 y 104 por ciento. La ocurrencia de enfermedad meningocócica en los no vacunados fue de 20,2 por ciento (23/114); 79,8 por ciento (91/114) en lactantes con edad de vacunación y en 75,8 por ciento (69/91) se precisó la fecha de inmunización. Tenían una sola dosis de vacuna aplicada 26,4 por ciento (24/91) y 73,6 por ciento (67/91) recibió el esquema completo (2 dosis). La enfermedad meningocócica predominó en los primeros 6 meses de edad, declinó a partir de este momento y comenzó de nuevo su ascenso a los 10 y 11 meses. Predominó la forma meníngea (89,5 por ciento); la letalidad general fue de 7 por ciento (8/114), con 4,4 por ciento para la meningococemia y 2,6 por ciento para la meningitis. Conclusiones: la efectividad de VA-MENGOC-BC® fue satisfactoria. Se sugiere realizar un análisis por un grupo de expertos sobre la necesidad de aplicar una tercera dosis(AU)
Introduction: meningococcal disease is an important health problem worldwide. Since 1991 the vaccine VA-MENGOC-BC has been used in Cuban under one-year old infants. Objective: to evaluate the effectiveness of the vaccine VA-MENGO-BC®. Methods: for the evaluation after licensing this vaccine, all the infants affected by meningococcal disease between 1997 and 2008 were studied. Results: a total number of 114 cases were recorded. The annual average incidence was 7.1 per 100 000 infants. The mean vaccinal effectiveness for the period was 84.0 percent, ranging from 68 percent to 104 percent. The frequency of disease in unvaccinated children was 20.2 percent (23/114); 79.8 percent (91/114) within the vaccination age, but only 75.8 percent (69/91) of them had confirmed the immunization date. Only 26.4 percent (24/91) had one single dose applied whereas 73.6 percent (67/91) had completed their vaccination schedule (2 doses). The meningococcal disease prevailed in the first six months of life, declined afterwards and then started to rise again at 10 and 11 months of age. The meningeal form of clinical presentation predominated (89.5 percent); case-fatality rate was 7.0 percent (8/114), being 4,4 percent for meningococcemia and 2,6 percent for meningitis. Conclusions: the vaccine VA-MENGOC-BC® effectiveness in infants was satisfactory. It is suggested that further analysis be made by a group of experts on the use of a booster dose.(AU)

OBJECTIVE: To describe an adapted version of the Pan American Health Organization (PAHO) methodology for rapid monitoring of vaccination coverage and its use as a supervisory tool to guide decision-making and strategies for end-stage vaccination activities ("mopup" operations) following a six-week national rubella elimination campaign in Brazil. METHODS: Vaccination coverage assessments modeled on a variation of PAHO's rapid house-to-house coverage monitoring methodology were conducted by Brazilian municipalities following mass immunization of adults and adolescents from August to December 2008. Results of monitoring assessments conducted in 3 658 (65.7 percent) of 5 564 municipalities were reported to Brazil's National Immunization Program. RESULTS: Information on vaccination against rubella was obtained from more than 1.5 million Brazilians (2.1 percent of the 70.1 million people targeted for immunization) during vaccination coverage monitoring. According to the assessment data, vaccination targets of 95 percent coverage were reached in 2 175 (59.5 percent) of the 3 658 municipalities that reported results. The percentage of municipalities that reached coverage targets was lower than administrative coverage estimates (number of vaccine doses administered divided by the immunization target population). These results informed targeted "mop-up" campaigns to reach unvaccinated populations. CONCLUSIONS: Rapid coverage monitoring implemented at the local level proved useful for deciding when to conclude vaccination activities and where to focus additional efforts to achieve desired coverage.
Describir una versión adaptada de la metodología de la Organización Panamericana de la Salud (OPS) para el monitoreo rápido de la cobertura de vacunación. Exponer su uso como herramienta de supervisión para guiar la toma de decisiones y las estrategias para las actividades de vacunación finales (campañas "de barrido") después de una campaña nacional de eliminación de la rubéola de 6 semanas de duración en el Brasil. MÉTODOS: Los municipios brasileños llevaron a cabo una evaluación de la cobertura de vacunación basada en una variante de la metodología de monitoreo rápido "casa por casa" de la OPS, después de una campaña masiva de vacunación de adultos y adolescentes efectuada entre agosto y diciembre del 2008. Los resultados de las evaluaciones de seguimiento realizadas en 3 658 (65,7 por ciento) de 5 564 municipios se comunicaron al Programa Nacional de Vacunación del Brasil. RESULTADOS: Mediante el monitoreo de la cobertura de vacunación se obtuvo información sobre la vacunación antirrubeólica de más de 1,5 millones de brasileños (2,1 por ciento de los 70,1 millones de destinatarios de la inmunización). Según estos datos, se alcanzó la meta de vacunación (cobertura del 95 por ciento) en 2 175 (59,5 por ciento) de los 3 658 municipios que presentaron resultados. El porcentaje de municipios que alcanzaron la meta de cobertura fue menor que las estimaciones de cobertura administrativa (cantidad de dosis de vacuna administradas dividida por la población destinataria de la inmunización). Estos resultados se usaron para las campañas de vacunación "de barrido" a fin de alcanzar a las poblaciones no vacunadas. CONCLUSIONES: El monitoreo rápido de la cobertura de vacunación en el nivel local resultó útil para decidir cuándo concluir las actividades de vacunación y en qué aspectos se debían concentrar los esfuerzos posteriores para lograr la cobertura deseada.

OBJETIVO: Avaliar o programa de imunização de crianças de 12 e de 24 meses de idade, com base no registro informatizado de imunização. MÉTODOS: Estudo descritivo em amostra probabilística de 2.637 crianças nascidas em 2002 e residentes em Curitiba, PR. As fontes de dados foram: registro informatizado de imunização do município, Sistema de Informação de Nascidos Vivos e inquérito domiciliar para casos com registro incompleto. As coberturas foram estimadas aos 12 e aos 24 meses de vida e analisadas segundo características socioeconômicas de cada distrito sanitário e o vínculo das crianças aos serviços de saúde. Foram analisadas a abrangência, completude e duplicidades do registro informatizado de imunização. RESULTADOS: A cobertura do esquema de imunização foi de 95,3 por cento aos 12 meses sem diferenças entre os distritos e de 90,3 por cento aos 24 meses, tendo sido mais elevada em um distrito com piores indicadores socioeconômicos (p = 0,01). A proporção de vacinas, segundo o tipo, aplicadas antes e após a idade recomendada foi de até 0,9 por cento e até 32,2 por cento, respectivamente. A cobertura do registro informatizado de imunização foi de 98 por cento na amostra estudada, o sub-registro de doses de vacinas foi de 11 por cento e a duplicidade de registro foi de 20,6 por cento. Os grupos que apresentaram maiores coberturas foram: crianças com cadastro definitivo, aquelas com três ou mais consultas pelo Sistema Único de Saúde e as atendidas em Unidades Básicas de Saúde que adotam plenamente a Estratégia de Saúde da Família. CONCLUSÕES: A cobertura vacinal em Curitiba mostrou-se elevada e homogênea entre os distritos, e o vínculo com os serviços de saúde foi fator importante para tais resultados. O registro informatizado de imunização mostrou-se útil no monitoramento da cobertura vacinal; no entanto, é importante a prévia avaliação do seu custo-efetividade para que seja amplamente utilizado pelo Programa Nacional de Imunização.
OBJECTIVE: To evaluate the immunization program for 12 and 24-month-old children based on electronic immunization registry. METHODS: A descriptive study of a random sample of 2,637 children born in 2002 living in the city of Curitiba, Southern Brazil was performed. Data was collected from local electronic immunization registers and the National Live Birth Information System, as well as from a household survey for cases with incomplete records. Coverage at 12 and 24 months was estimated and analyzed according to the socioeconomic characteristics of each administrative district and the child's enrollment status in the health care service. The coverage, completeness, and record duplication in the registry were analyzed. RESULTS: Coverage of immunization was 95.3% at 12 months, with no disparities among administrative districts, and 90.3% at 24 months, with higher coverage in a district with lower socioeconomic conditions (p < 0.01). The proportion of vaccines, according to type, given before and after the recommended age reached 0.9% and 32.2%, respectively. In the surveyed sample, electronic immunization registry coverage was 98%, underreporting of vaccine doses was 11%, and record duplication was 20.6%. Groups with highest coverage included children with permanent records, children with three or more appointments through the National Unified Health Care System, and children seen within Primary Health Care Facilities fully adopting the Family Health Strategy. CONCLUSIONS: Vaccination coverage in Curitiba was high and homogeneous among districts, and health service enrollment status was an important factor in these results. The electronic immunization registry was a useful tool for monitoring vaccine coverage; however, it will be important to determine cost-effectiveness prior to wide-scale adoption by the National Immunization Program.

O objetivo deste estudo foi avaliar a cobertura vacinal de crianças de 12 a 23 meses de idade residentes no município se Sarandi, PR. Para tanto foi realizado inquérito domiciliar, de dezembro de 2003 a março de 2004, para verificar as carteiras de vacinação das crianças residentes. A cobertura vacinal foi analisada segundo sexo, idade, tipo de vacina e município de realização da vacina. Das 740 carteiras de vacina avaliadas 77,6% constava esquema vacinal completo, sem diferença quanto ao sexo. As coberturas mais altas ocorreram para a BCG de 99,6%, para a vacina DTP/Tetra de 98%, para a Pólio de 97,2% e para a Hepatite B de 96,2%. Somente 31,1% das crianças com 12 meses de idade apresentavam esquema vacinal completo. As vacinas BCG e DTP/Tetra tiveram maior taxa de evasão, 13,9% e 11%, respectivamente. Entre as estratégias para melhorar as taxas de cobertura vacinal e realização das vacinas nos intervalos preconizados pelo Ministério da Saúde, destacam-se a capacitação da equipe de enfermagem, do aprimoramento do acesso e da qualidade do atendimento nos serviços de saúde e nas salas de vacina.
The objective of this study was to evaluate the immunization coverage in children from12 to 23 months of age resident in the municipality of Sarandi/PR-Brazil. For that a household interview survey was carried out to verify the vaccine cards of the resident children. Home visits were accomplished from December of 2003 to March of 2004. The vaccine coverage was analyzed according to gender, age, vaccine type and city of vaccination. Of the 740 vaccine cards assessed, 77.6% had the complete vaccine doses, with no difference regarding gender. The highest coverage was 99.6% for BCG, 98% for DTP/Tetra, 97.2% for Polio, 96.2% for Hepatitis B. Only 31.1% of children aged 12 months old had the complete vaccine coverage. The BCG and DTP/Tetra vaccines had the greatest rate of evasion, 13.9% and 11%, respectively. Among the strategies to improve the vaccine coverage rates and the taking of vaccines in the standardized dates established by the Health department, it is worth mentioning the improvement of the access and the quality of the attendance in the vaccine rooms.

Objetivo Evaluar el estado vacunal en la población de 0 a 23 meses por conglomerado (localidad) de Bogotá e identificar los motivos de no vacunación. Materiales y métodos Se realizó un estudio descriptivo retrospectivo, calculando el tamaño muestral de la población objeto (niños de 0-23 meses), para conocer la situación de vacunación del recién nacido, evaluar la vacunación regular oportuna de polio y pentavalente, hacer seguimiento a la vacunación regular de polio y pentavalente con terceras dosis y la vacunación oportuna con triple viral. Resultados Se encuestaron 5 845 niños, 96,7 por ciento presentaron carné de vacunación; 75,3 por ciento estaban vinculados al Sistema General de Seguridad Social en Salud y 12,6 por ciento (713/5 845) no vacunados. Por biológico, las coberturas de vacunación fueron: BCG: 99,1 por ciento; pentavalente: 93,0 por ciento; polio: 93,2 por ciento; triple viral: 85 por ciento; por oportunidad de aplicación: BCG 5 328 (94,3 por ciento); polio: 1.256 (88,6 por ciento); pentavalente en promedio 1 112 (88,5 por ciento); y, triple viral: 1 702 (69,6 por ciento) con el mayor número de errores en la vacunación: 33 (1,3 por ciento). Causas de no vacunación identificadas: 59,2 por ciento logística y organización de los servicios de salud; 27,9 por ciento falsas creencias de los padres; y, 12,8 por ciento niño no afiliado. Conclusiones Se evidenciaron coberturas útiles y oportunas de vacunación con BCG y dificultades en el registro de pentavalente. Se requieren estrategias de educación y comunicación masiva, tendientes a contrarrestar los motivos de no vacunación y reforzar la aplicación oportuna de los biológicos.
Objective Evaluating vaccination coverage in the infant population aged 0-23 months by cluster (locality) in Bogotá and identifying reasons for the lack of vaccination coverage. Materials and Methods This was a descriptive, retrospective study. Sample size was calculated on target population (children aged 0-23 months), further divided into 0-1, 2-6, 7-11 and 12-23 month sub-groups by tri-stage sampling to ascertain newborn vaccination status, evaluate opportune oral polio vaccine (OPV) and pentavalent vaccine third dose vaccination and opportune measles, mumps and rubella (MMR) vaccination. Results 5 845 children were surveyed; 96.7 percent had immunisation cards, 75.3 percent were registered in the Social Protection System and 12.6 percent (713 out of 5 845) had not been vaccinated. Vaccination coverage by biological products was as follows: 99.1 percent BCG, 93.0 percent pentavalent vaccine, 93.2 percent OPV, 85 percent MMR. Vaccination opportunity was 5 328 for BCG (94.3 percent), 1 256 for OPV (88.6 percent), 1 112 for pentavalent (88.5 percent) and 1,702 for MMR (69.5 percent) with 33 vaccination errors (1.3 percent). Among the identified reasons for non-vaccination were confused health service logistics and coordination (59.2 percent), misguided parental beliefs (27.9 percent) and unregistered children (12.8 percent). Conclusions Useful and timely vaccine coverage was evident with BCG; there were difficulties regarding recording pentavalent vaccination. Information, education and mass communication strategies must be developed to counteract reasons given for non-vaccination and to educate parents and tutors in its opportune application to increase triple-viral vaccine coverage.

En Uruguay se recomienda la vacuna antigripal en forma gratuita desde el año 2004. El objetivo del estudio fue conocer el porcentaje de niños vacunados entre los 6 y 23 meses y las causas de la vacunación o no vacunación. Metodología: estudio descriptivo. Se entrevistó a padres de niños de 6 a 23 meses en el período de vacunación. Se calcularon porcentajes y se utilizó el test de Fisher y c2. Resultados: de 414 niños, 126 (30,4%) recibieron la vacuna. Se vacunaron más niños del sector privado que del público. El motivo más importante para la vacunación fue la indicación del pediatra en 106 (84,1%) de ellos; para no vacunar la falta de recomendación: 147 (51,0%). Conclusiones: el porcentaje de vacunación es bajo. Se debe trabajar para mejorar la adhesión del pediatra a la vacuna y lograr mejor cobertura.
In Uruguay, free-of-charge vaccination against influenza has been recommended since 2004. The objective of this study was to determine the percentage of vaccinated children aged from 6 to 23 months Methodology: it was a descriptive study surveying the parents of children aged from 6 to 23 months in the vaccination period. Results: 126 (30,4%) of 414 children received the vaccine. The most important reason was the pediatrician's prescription in 106 (84,1%); the lack of such recommendation was the most important reason for failing to do so: 147 (51,0%). Conclusions: the vaccination percentage is very low. Awareness should be raised in order to improve vaccination compliance and to achieve a better coverage.
