No evidence suggests that women receiving a vaccine against SARS-CoV-2, the virus that causes COVID-19, is harmful to either the nursing mother or the breastfed infant. Antibodies appear in the milk after maternal vaccination, which neutralize the SARS-CoV-2 virus and likely protect the infant against COVID-19 infection[1,2] Professional organizations and governmental health authorities have recommended that COVID-19 vaccines be offered to those who are breastfeeding because the potential benefits of maternal vaccination during lactation outweigh any theoretical risks, including mothers with diabetes mellitus.[3-14] Nursing mothers experienced minimal disruption of breastfeeding after vaccination and noticed no serious adverse effects in their infants.[15-19]
