Passive immunity from immunised mother: A nano-structural consideration on transplacental and breast milk passage to neonate

Abstract

Immunization against COVID-19 by vaccination is a good way of controlling the pandemic. However, COVID-19 vaccine is not currently recommended for the newborn. How to promote immunity in the newborn is very interesting. At present, COVID-19 vaccination has proven safe and it is planned to be used in pregnant mothers1,2. The passage of passive immunity to the neonate is an interesting phenomenon. In brief, there are two main passages of passive immunity from mother to neonate either via breastmilk or transplacental.
