Abstract

Coronavirus 2019 (COVID-19) has created a global pandemic. According to statistics of the World Health Organization (WHO), by August 2021, more than 200 million people have been infected with Covid - 19, of which more than 4 million have died worldwide [1]. Many effective and safe COVID-19 vaccines have been developed. However, research data in the process of developing vaccines on breastfeeding women is still limited, especially in Vietnam. Therefore, data on the safety of this vaccine for special populations is in fact extremely important. The study carried out the topic with the goal of surveying knowledge, attitudes, and adverse events after vaccination against Covid-19 in breastfeeding women. Subjects, research methods: A cross-sectional description of responses from nursing women who received the Covid-19 vaccine were randomly and conveniently collected nationwide through an online questionnaire with a link https:// forms.gle/sK9gWneMaZ75pJNJ8. Results: sample of 89 breastfeeding women who received Covid-19 vaccine, mean age 31.4 ± 3.49; The average age of the child was 9.43 ± 6.54 months, there were 4 vaccines - Covid 19 was injected: Comirnaty (22/89), Moderna (17/89), AstraZeneca (44/89), Verocell (4/89) . 76/89 injected 1 dose. Most learned about the Covid-19 vaccine (96.6%) mainly through social networks and online newspapers (80.9%). 100% are willing to get vaccinated against Covid-19 and 96.6% agree that vaccination brings benefits that outweigh the risks, but most are worried about adverse reactions affecting their children (78.7%). There were 79/89 cases of adverse events after injection on the mother, mainly myalgia, mild fever, fatigue, pain at injection site, no serious complications. There were 16/87 cases of adverse events in the baby (sleepiness, little feeding, fussiness, trouble sleeping). Breastfeeding immediately after vaccination did not increase the risk of adverse events in the infant with the CI (0.53-1.59) and there was no association between the vaccine and adverse events in the infant (P > 0.05). Conclusions: Breastfeeding women all agree that the benefits of the Covid-19 vaccine outweigh the risks, are ready to receive the Covid-19 vaccine, but are still worried about the events affecting the baby. Recorded some events that occurred in the child but were mild. There was no association between immediate breastfeeding, the Covid-19 vaccine and events occurring in the baby.
