“…The objective of our study was to describe the antibodies to sars cov 2 in infants of mothers vaccinated against covid-19, thus finding that if samples from mothers vaccinated against covid-19 are studied, whether serum, breast milk or even umbilical cord , there are positive data about the transmission of antibodies, which suggests the possibility of the presence of antibodies in newborns and possible immunological protection against Covid-19, comparing these results with information obtained in other studies that look for the immune response in newborns faced with different diseases, such as the flu or influenza, we have the study carried out by Shabir and collaborators where they carried out a study characterized by double-blind randomized controlled trials, where 2116 HIV-uninfected women included 194 HIV-infected women using placebo and inactivated trivalent influenza vaccine (IIV3) evaluating immunoglobulin enicity, safety and efficacy of the vaccine in pregnant women and their babies up to 24 weeks after birth, measuring immune responses using hemagglutination assays and PCR testing, finding that the influenza vaccine was immunogenic in both infected and non-infected pregnant women infected by HIV, presenting a partial proportion of protection against confirmed influenza in both groups and in babies, thus evidencing the transmission of antibodies from the mother to the fetus and providing immunity in the first weeks of life, when comparing these results with our research , we can investigate that there is a particular mechanism of transmission of maternal-fetal antibodies for various vaccines [12,14,15].…”
