A recent CDC report revealed that maternal completion of a 2-dose primary mRNA COVID-19 vaccine course during pregnancy reduced the risk of COVID-19 hospitalisation amongst infants <6 months. Data revealed that of 176 COVID-19 related paediatric hospitalisations, 148 (84%) of infants were born to mothers who were not vaccinated during pregnancy.
Transplacental transfer of SARS-CoV2-specific antibodies that may provide protection to infants is evident in women vaccinated during the later stages of pregnancy. Detectable COVID-19 antibodies were also present in breast milk, indicating a transfer of maternal antibodies to the baby.
This study demonstrates that mRNA COVID-19 vaccination in pregnant and breast-feeding women is safe and effective and provides increased protection to the baby.
