Influenza vaccination among healthcare workers at a tertiary care hospital in Saudi Arabia: Facing challenges

Sir, The World Health Organization (WHO) estimated that influenza virus causes worldwide severe illness in three to five million people annually, with up to half-million deaths.[1] Healthcare workers (HCWs) are at a great risk of developing influenza illness because of exposure to sick patients or other HCWs. Influenza vaccination remains the most effective measure for controlling and preventing influenza outbreak in a healthcare setting.[2] Although international guidelines require annual vaccination of HCWs against influenza,[3] influenza vaccine among HCWs remains considerably low.[4,5]
