The general panic caused by the coronavirus disease 2019 (COVID-19) pandemic spurred the demand for a safe and effective vaccine. Just a year after the initial report of a novel coronavirus emerging in Wuhan, China, later named the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), two vaccines were rolled out, both built on a messenger ribonucleic acid (mRNA) platform.
The question remains, are such vaccines safe during pregnancy and lactation, or will they unfavorably affect the fetus or neonate? A recent study attempts to answer this question in lactating women who received the vaccines within six months postpartum.
