La dosis de refuerzo está indicada una vez transcurridos los 4 meses (120 días) de la última dosis del esquema inicial y será con vacuna de plataforma ARNm: Pfizer-BioNTech pediátrica a partir de los 5 años o Moderna para uso pediátrico a partir de los 6 años.
La evidencia disponible a nivel internacional sobre el uso de un segundo refuerzo muestra una mayor duración de la respuesta inmune y una disminución de la internación y la mortalidad por COVID 19 en la población de adultos mayores y huéspedes inmunocomprometidos. Por otra parte, el personal de... salud se beneficiaría considerando el mayor riesgo de exposición y la caída de la respuesta inmune con el tiempo. En base a lo señalado previamente se recomienda incorporar y
priorizar un segundo refuerzo al esquema de vacunación contra la COVID-19 del:
- Personal de salud independientemente de la edad
- Personas de 50 años o mayores
- Personas de 12 años o más con inmunocompromiso
A la vez, se progresará de manera escalonada y simultánea con la vacunación de segundo refuerzo del:
- Personal estratégico
- Personas de 18 a 49 años con factores de riesgo
Continuando en la estrategia de segundo refuerzo todas las personas a partir de los 18 años. Las personas gestantes con indicación de segundo refuerzo, se recomienda vacunas de plataforma de ARNm (Pfizer-BioNTech o Moderna)

A very large number of people from Ukraine are fleeing the country and entering the European Union (EU) countries bordering Ukraine (Hungary, Poland, Romania, Slovakia) and the EU-neighbourhood country of the Republic of Moldova. Those fleeing Ukraine - mainly women and children - are ...currently dispersing into communities, but as more people congregate at border crossings it is likely that they will also need to be housed in reception centres.

A rapid evidence briefing. Vaccinated people are less likely to develop long COVID, even if they get infected, a rapid review of 15 studies by the UK Health Security Agency shows.
21 January 2022
The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).

interim guidance, 19 July 2021 (arabic version)
This training module is designed to equip HWs with knowledge and communication skills to build their confidence and support them in their ability to promote acceptance of COVID-19 vaccination among other HWs.
Many critical questions remain about the effectiveness of COVID-19 vaccines in real-world settings. These questions can only be answered in post-introduction vaccine effectiveness studies.This guidance document outlines an approach to leverage existing surveillance systems for Severe Acute Respirato...ry Infection (SARI) to estimate COVID-19 vaccine effectiveness (VE) in preventing SARI associated with laboratory-confirmed SARS-CoV-2 using existing SARI surveillance systems. The approach uses the test-negative design to evaluate VE; cases are SARI patients who tested positive for SARS-CoV-2, and controls are SARI patients who tested negative for SARS-CoV-2.
