ABSTRACT

Introduction:

Frontline health care workers (HCW) have higher risk than the general population to become infected by SARS.CoV.2, so they were a priority group for Covid-19 vaccine administration. We compared the incidence and prevalence of HCW infected pre-and post-vaccination with the BNT162b2 mRNA COVID-19 vaccine. Material and

methods:

Prospective observational study carried out between 01/12/20 and 07/03/21 in La Paz University Hospital, Madrid (Spain). SARS.CoV.2 positive cases in HCW after vaccination were collected and compared to those hospitalized COVID-19 patients at the same hospital.

Results:

Two weeks after finishing the first round of vaccinations daily new cases of HCW infections (symptomatic and asymptomatic) decreased substantially and cumulative cases of infected HCW and hospitalized COVID-19 patients started to diverge. No new positive cases of HCW infection were registered seven days after the second dose of BNT162b2 mRNA COVID-19 vaccine.

Conclusions:

BNT162b2 mRNA COVID-19 vaccine is highly effective in Spanish HCW.(AU)
RESUMEN

Introducción:

Los trabajadores sanitarios (TS) de primera línea tienen mayor riesgo de infectarse de SARS-CoV-2 que la población general, por lo que han sido un grupo prioritario para la vacunación frente a COVID-19. Comparamos la incidencia y prevalencia de TS infectados antes y después de la vacunación con BNT162b2 mRNA frente a COVID-19. Material y

métodos:

Estudio prospectivo observacional realizado entre 01 de diciembre de 2021 en el Hospital Universitario La Paz, Madrid, España. Se registraron los casos positivos para SARS-CoV-2 en TS y se compararon con los hospitalizados por COVID-19.

Resultados:

Dos semanas tras la primera ronda de vacunación las nuevas infecciones en TS (sintomáticas y asintomáticos) disminuyeron sustancialmente y los casos acumulados de TS infectados y pacientes hospitalizados por COVID-19 empezaron a divergir. No hubo nuevas infecciones en TS vacunados a los siete días de la segunda dosis de la vacuna.

Conclusión:

La vacuna BNT162b2 mRNA frente a SARS-CoV-2 es altamente eficaz en TS españoles.(AU)
