Study On The Spanish Population’s Opinion On The COVID-19 Vaccine

This cross-sectional study aims to determine the attitude of the Spanish population towards vaccination against COVID-19

Keywords: vaccination hesitancy; COVID-19; perception; socio-cultural factors


164 participants stated that they would not be vaccinated (22.43%), of which:

– 20-24% were not health workers or were unemployed,
– 17.5% were doctors,
– 31.5% were other health workers,
– almost 35% were nurses.

Description of the Study:

  • Title: Spain’s Hesitation at the Gates of a COVID-19 Vaccine.
  • Principal Investigators: Francesc Saigí-Rubió, Hans Eguia, Franco Vinciarelli,Marina Bosque-Prous and Troels Kristensen.
  • Study Population: 731 Spanish individuals.
  • Study Type: Cross-sectional study.
  • Methods: Participants were recruited using Twitter® as a dissemination tool to reach as many respondents as possible in different parts of Spain. Data were collected between 10 September and 23 November 2020 using an online questionnaire. Respondents answered questions about whether they intended to be vaccinated and provided the main reason for their answers. To estimate associations between vaccination hesitancy and the independent variables, Poisson regression models with robust variance were fitted.

Objectives of the Study:

Principal Objective:  To delineate a pattern on vaccine hesitancy in a sample of the Spanish population, considering age groups and status as healthcare workers.

More about this Study:

Scientific Context: Many research studies on COVID-19 vaccine hesitancy have been conducted in Europe, the United States and Asia, but not in Spain. It is crucial to determine the attitude of the population towards COVID-19 vaccination, as to manage the COVID-19 pandemic it is necessary to identify the factors of vaccine hesitancy in the population. We need more than 70% of vaccinated people in a community to achieve herd immunity, which means that vaccination alone is not enough.

To design appropriate policies for COVID-19 vaccination, negative public perceptions must first be identified and counteracted. The wrong policy could generate more rejection than affinity.

To identify potential factors related to hesitancy to vaccinate against COVID-19, Thomson’s “5As” have been considered to describe vaccine uptake: access, affordability, awareness, acceptance and activation. Consideration of these factors will allow the likelihood of vaccine refusal to be established even before the vaccine is available; it will also allow models to be established that can be used to combat vaccine hesitancy.
