“…This has resulted in vaccine hesitancy for COVID-19 vaccines among lactating women (Saus-Ortega, 2021) and difficulty for clinicians counseling lactating women on the risks–benefits of COVID-19 vaccination. Vaccination of a lactating woman is important to protect her from COVID-19, and continued breastfeeding after vaccination can provide her infant with passive immunity through the transfer of protective milk antibodies (Low et al, 2021).…”

Background: Pre-approval clinical trials of the Pfizer/BioNTech messenger RNA COVID-19 vaccine, BNT162b2 did not include participants who were breastfeeding. Therefore, there is limited evidence about outcomes of breastfeeding mother–child dyads and effects on breastfeeding after vaccination. Research Aims: To determine: (1) solicited adverse effects (e.g., axillary lymphadenopathy, mastitis, and breast engorgement), which are unique to lactating individuals; and (2) systemic and local adverse effects of COVID-19 mRNA vaccine on mothers and potential effects on their breastfed infants. Method: This was a prospective cohort study of lactating healthcare workers ( N = 88) in Singapore who received two doses of BNT162b2 vaccination (Pfizer/BioNTech). The outcomes of mother–child dyads within 28 days after the second vaccine dose were determined through a participant-completed questionnaire. Results: Minimal effects related to breastfeeding were reported by this cohort; three of 88 (3.4%) participants had mastitis, one (1.1%) participant experienced breast engorgement, five of 88 (5.7%) participants reported cervical or axillary lymphadenopathy. There was no change in human milk supply after vaccination. The most common side effect was pain/redness/swelling at the injection site, which was experienced by 57 (64.8%) participants. There were no serious adverse events of anaphylaxis or hospital admissions. There were no short-term adverse effects reported in the infants of 67 lactating participants who breastfed within 72 hr after BNT162b2 vaccination. Conclusions: BNT162b2 vaccination was well tolerated in lactating participants and was not associated with short-term adverse effects in their breastfed infants. Study Protocol Registration: The study protocol was registered at clinicaltrials.gov (NCT04802278).

“…In similar cases, some were advised to stop lactation, and other women were not vaccinated because they were nursing mothers. Therefore, it is not just about “saying that the leading professional organizations and associations recommend it does not seem to be enough to convince mothers” (Saus-Ortega, 2021). First, clinicians responsible for vaccination should give updated and verified information so the patients can make their own decision.…”
