Attitudes of Spanish hospital staff towards COVID-19 vaccination and vaccination rates.

COVID-19 vaccination uptake was higher than previously estimated according to the stated intentions of HCW. Doubts and fears must be addressed, particularly in persons less inclined to be vaccinated: females, younger people and those not vaccinated against influenza in recent seasons. The study of barriers and strategies aimed at promoting COVID-19 vaccination must be adapted in relation to occupational groups' attitudes, understanding their idiosyncrasies with respect to this and other vaccines.
