ABSTRACT

OBJECTIVE: To compare the reactogenicity between the types of mRNA Commirnaty® (Pfizer) and Spikevax® (Moderna) vaccines against COVID-19 in a healthcare population. METHODS: Cross sectional study of short-term adverse effects and their consequences (sick leave, limitations of daily life, etc.) after the administration of the first and second doses of both vaccines in professionals and students of a health institution. A questionnaire on symptoms and their consequences was administered seven days after each vaccination dose. The prevalence and 95% confidence interval (95%CI) were calculated. Differences between vaccines were quantified using the odds ratio (OR) and its 95%CI. RESULTS: The questionnaire was completed by 1924 and 1170 healthcare providers (response rates 62.2% and 39.1%) after the first and second doses, respectively, of the Commirnaty® vaccine, and 410 (56.0%) and 107 (15.0%) of Spikevax®. After the first dose of Comirnaty®, 67.4% presented some adverse effect, and 76.1% for Spikevax® (OR 1.5 95%CI 1.2-1.9). In general, women and young people showed greater reactogenicity and differences between vaccinSpain. Consequences of adverse effects were more frequent for Spikevax®. The reactogenicity was higher after the second than the first dose, for both vaccines (Comirnaty®: 67.4% vs. 75.6%; Spikevax®: 76.1% vs. 87.9%. CONCLUSIONS: The greater reactogenicity and its consequences, for the first and second dose of the Spikevax® vaccine compared to Comirnaty®, and of the second dose compared to the first dose of both vaccines, provides useful knowledge for planning vaccination against COVID-19 campaigns in healthcare settings.


OBJETIVO: Comparar la reactogenicidad entre los tipos de vacuna RNAm Commirnaty® (Pfizer) y Spikevax® (Moderna) frente a la COVID-19 en población sanitaria. Métodos: Estudio de prevalencia de los efectos adversos a corto plazo y sus consecuencias tras la administración de la primera y segunda dosis en profesionales y estudiantes de una institución sanitaria. Se administró un cuestionario de síntomas y sus consecuencias a los 7 días de la vacunación. Se calculó la prevalencia e intervalo de confianza del 95% (IC95%). Las diferencias entre vacunas se cuantificaron mediante las odds ratio (OR) e IC95%. RESULTADOS: Completaron el cuestionario 1924 y 1170 sanitarios (tasas de respuesta 62.2% y 39.1%) tras la primera y la segunda dosis, respectivamente, de la vacuna Commirnaty®, y 410 (56.0%) y 107 (15.0%), de Spikevax®. Después de la primera dosis de Comirnaty® un 67,4% presentó algún efecto adverso, y un 76,1% para Spikevax® (OR 1,5 IC95% 1,2-1,9). En general mujeres y jóvenes mostraron mayor reactogenicidad y diferencias entre vacunas. Las consecuencias de los efectos adversos fueron más frecuentes para Spikevax®. La reactogenicidad fue superior tras la segunda dosis que tras la primera, para las dos vacunas (Comirnaty® 67,4% vs. 75,6%; Spikevax® 76,1% vs. 87,9%). CONCLUSIONES: La mayor reactogenicidad y sus consecuencias, para la primera y segunda dosis de la vacuna Spikevax® respecto a Comirnaty®, y de la segunda dosis respecto a la primera dosis de ambas vacunas, aporta conocimiento útil para la planificación de campañas de vacunación frente a la COVID-19 en el entorno sanitario.

ABSTRACT

Objetivos: La varicela es frecuente en centros sanitarios existiendo escasos datos de seroprevalencia en sus trabajadores (TS). Este estudio tiene como objetivo estimar la susceptibilidad a la varicela entre TS y la respuesta serológica postvacunación. Métodos: Se analiza la primera serología frente varicela por método ELISA en trabajadores de empresas sanitario-sociosanitarias de Catalunya, entre 2004-2013 (2958 trabajadores) según: género, edad, cohortes previas y posteriores a introducción vacuna en calendario de vacunación de Catalunya y en puestos de trabajo con o sin riesgo de exposición según la evaluación de riesgos. La respuesta serológica postvacunal se determinó mediante método ELISA, frente a virus de la varicela a los 2 meses de haber administrado la segunda dosis de vacuna VARIVAX(R) en 59 trabajadores con seroprotección negativa previa. Resultados: 2820 trabajadores (95,33%) presentaron tasas protectoras (TP) a varicela, 507 hombres (97,13%) y 2313 mujeres (94,95%). Las cohortes de nacidos en 1993 o anteriores presentaban TP del 95,41% y las posteriores a 1993 del 80,0%. En los puestos de trabajo con riesgo de exposición la TP fue de 95,18% y en los sin riesgo fue 95,98%. Por edad la TP inferior se establece en ≥60 años (93,33%). La respuesta serológica post-vacunación fue del 89,83%. Conclusiones: Las TP son similares a las esperadas según los últimos estudios de seroprevalencia de población general en Catalunya. Los hombres presentan TP significativamente más elevada que las mujeres. Los nacidos después de 1993 presentan TP significativamente más bajas que los nacidos en 1993 y anteriores


Aims: Chickenpox is a frequent and contagious disease in healthcare and social assistance settings, and there are limited data on seroprevalence among workers in this sector. We estimated susceptibility to chickenpox among workers, by demographic and occupational variables, and measured the rate of seroprotection after vaccination. Methods: A retrospective seroprevalence study of chickenpox (varicella) and serological vaccine response. The earliest recorded varicella serology, analyzed by the ELISA method, was identified for each worker from a health surveillance database of a group of medical and healthcare companies in Catalonia, recorded between 2004 and 2013. The total study population consisted of 2958 workers, analyzed by gender, age, birth cohort preceding and following the introduction of the vaccine in the vaccination schedule of Catalonia (born after 1993), and occupational category, regardless of exposure risk. Vaccine effectiveness was determined in a group of 59 initially seronegative workers by measuring ELISA-based varicella titers, obtained at least 2 months after receiving a second dose of the VARIVAX(R) vaccine. Results: 2820 workers (95.3%) had protective titers (PT) to chickenpox; 507 were men (97.1%) and 2313 were women (95%). The 1993 and earlier birth cohorts had a PT of 95.4% and those born after 1993 had a PT of 80.0%. Among at-risk categories, the PT was 95.2%, whereas among those not at risk it was was 96%. By birth decade, the lowest PT was among those age 60 years or older (93.3%). The postvaccination serological response was 89.8%. Conclusions: The prevalence of protective varicella serologies among healthcare and social assistance workers was similar to that found in recent seroprevalence studies in the general population in Catalonia. Men have significantly higher rates of protection than women. Those born after 1993 have significantly lower rates of protective titers than those born in 1993 or earlier

ABSTRACT

Objetivo: La vacuna de la hepatitis A está indicada para colectivos de riesgo, incluidos los profesionales sanitarios. El objetivo fue conocer la prevalencia de anticuerpos frente al virus de la hepatitis A (IgG) en trabajadores de este ámbito, para establecer criterios de vacunación. Métodos: Estudio transversal y analítico con 4864 trabajadores de cuatro empresas sanitarias de Cataluña. El registro incluyó datos personales, categoría profesional, lugar de trabajo y serología. Resultados: La prevalencia global de anticuerpos fue del 52,7%. Se observó un incremento significativo con la edad: la media de los seropositivos fue de 41,5 años, frente a 34,3 años la de los seronegativos. Los colectivos de limpieza y cocina presentan una mayor prevalencia de anticuerpos (limpieza 74,2% y cocina 75,3%). Discusión: Considerando la alta prevalencia de adultos seronegativos, susceptibles de contraer la infección, y teniendo en cuenta las características de su actividad profesional, se sugiere valorar la indicación de vacunar a todo el personal que trabaja en instituciones sanitarias (AU)


Objective: Vaccination against hepatitis A is recommended in risk groups, including healthcare workers. The objective of this study was to determine the prevalence of antibodies to HAV (IgG) among workers in the healthcare setting in order to establish criteria for vaccination. Methods: A cross-sectional, analytic, observational study of 4,864 employees was undertaken in four healthcare companies in Catalonia (Spain). The variables gathered included personal data, professional category, location of employment, and serology. Results: The overall prevalence of antibodies to HAV was 52.7%. The prevalence significantly increased with greater age. The mean age of seropositive workers was 41.5 years compared with 34.3 in workers with negative serology. The highest prevalence of antibodies was found in cleaning employees (74.2%) and catering staff (75.3%). Discussion: Given the high prevalence of seronegative adults susceptible to infection and the characteristics of their professional activities, vaccination of all staff working in health institutions should be considered (AU)

ABSTRACT

Objetivos. Valorar y comparar los efectos indeseados de la vacuna de la gripe estacional (VGE) y vacuna de la gripe AH1N1 (VGA) en trabajadores sanitarios. Métodos. Estudio transversal multicéntrico en trabajadores sanitarios de hospitales de agudos, centros de asistencia primaria, centros sociosanitarios, centros de salud mental y un hospital geriátrico participantes en la campaña de vacunación antigripal del 2009. Se enviaron encuestas autocumplimentadas a todos los vacunados con VGE y/o VGA. Resultados. De los 1123 vacunados con VGE se obtienen 527 encuestas válidas (46,9%) y de 461 vacunados con VGA se obtienen 242 encuestas (52,5%). De los trabajadores participantes 527 estaban vacunados sólo con VGE, 117 vacunados previamente con VGE y después VGA (VGE+VGA) y 125 sólo vacunados sólo con VGA. El 18,4% (IC 95% 15,1-21,7) del grupo VGE presentaron algún efecto adverso a la vacuna VGE; en el grupo VGE+VGA el 45,3% (IC 95% 36,3-54,3) presentó una reacción adversa al recibir la VGA, y en el grupo VGA fue el 46,4% (IC 95% 37,7-55,1). En todos los participantes el problema más frecuente fue una reacción local. Las mujeres presentan mayor reacción a VGA y VGE que los hombres. Para todas las edades la VGE es menos reactógena que VGA y que la combinación de ambas vacunas, con la excepción de los trabajadores menores de 29 años. Conclusiones. La VGA es más reactógena que la VGE, sin diferencias por orden de administración. Se observan variaciones por sexo y edad, pero siempre con mayor reactogenicidad para la VGA(AU)


Objectives. To assess and compare adverse effects of Seasonal Influenza Vaccine (SIV) and new Influenza A(H1N1)Vaccine (AIV) in health care workers. Methods. Multicenter cross-sectional study in health care workers from acute care hospitals, primary health care centers, social centers, mental health centers and a geriatric hospital participating in the 2009 vaccination campaign. Self-administered questionnaires were sent to all workers vaccinated with SIV and/or AIV. Results. 527 valid questionnaires were collected out of 1123 sent to SIV vaccinated workers (46.9%), and 241 out of 461 sent to AIV vaccinated workers (52.5%). Participant workers include 527 vaccinated only with SIV, 117 first vaccinated with SIV and later with AIV (SIV+AIV), and 125 vaccinated only with AIV. Overall, 18.4% (95% CI 15.1-21.7) of workers vaccinated only with SIV reported adverse effects, as compared to 45.3% (95% CI 36.3-54.3) reporting adverse effects to AIV in the SIV+AIV group and 46.4% (95% CI 37.7-55.1) of workers vaccinated only with AIV. In all participants the most common adverse effect was a local reaction. Women were more reactive to both SIV and AIV than men. In all age groups SIV vaccination alone caused fewer reactions than either AIV only or the combination of SIV+AIV, with the exception of workers below 29 years of age. Conclusions. AIV was associated with more reactions than SIV, with no differences observed in relation to administration sequence. There were differences by sex and age, but reactions always occurred more commonly with AIV(AU)
