Medical ethics questions of COVID-19 vaccination in pregnant and lactating women in East Asia and Oceania

: We aimed to investigate some of the medical ethics issues that characterize the COVID-19 vaccination phase in pregnancy and breast-feeding. A literature search was conducted using PubMed, Scopus, Web of Science, focusing mainly on the countries of East Asia and Oceania. Vaccination during pregnancy and breastfeeding appears to help protect babies from COVID-19 by enabling antibodies to pass from mother to baby. However, individual countries of the same continent may adopt conflicting policy positions. Not only that, indications on the type of vaccine sometimes vary, depending on whether a woman is pregnant or breastfeeding. In this review we have taken into considerationp the policy positions on pregnancy and lactation by country and type of Covid-19 vaccine in East Asia and Oceania. Ten out of the 18 countries considered (representing more than two thirds of the population of East Asia and Oceania) provide different vaccine indications for pregnant and breastfeeding women. Can this diversity of recommendations be seen as a form of optimal protection for women in these categories, or does it suggest that some countries have taken a defensive position to avoid compensation claims in the event of complications? Is it ethically correct to leave questions concerning informed consent open? Misin-formation during a health crisis leaves people without protection and with increased vaccine hesitancy, especially for vulnerable populations in hard-to-reach areas of East Asia and Oceania.
