Breastfeeding Women's Attitudes About the SARS-COV-2 Vaccine in Spain

Severe Acute Respiratory Syndrome Coronavirus 2 has spread globally, causing the coronavirus disease 2019 (COVID-19) pandemic. To control the pandemic and to achieve herd immunity, four vaccines have obtained market authorization in Europe. Researchers have reported that the sequence of administration of the vaccines depends on the risk of exposure to COVID-19 and age, recommending the vaccine to pregnant and breastfeeding women.

To examine the knowledge, willingness and attitudes of breastfeeding women in Spain regarding the possibility of receiving the COVID-19 vaccine.

An observational descriptive cross-sectional study in two tertiary-level hospitals from Valencia was conducted. Breastfeeding women (N = 301) were recruited by non-probability sampling of consecutive cases. Questionnaires were collected in June 2021.

More than one in every two participants would accept a COVID-19 vaccine, and the percentage rose in participants who were older, more educated, or worked in high-risk jobs. Their main source of information was the Internet, and midwives were the professionals who most recommended vaccination. Participants who would not accept vaccination during lactation reported reasons linked to lack of information regarding vaccination in their condition and how it might affect newborns.

It is of primary concern for healthcare professionals to foster a greater understanding by providing updated information regarding the need, safety, and efficacy of the vaccine for both lactating mothers and their newborns.
