1/6) I am happy to share our preprint where we provide new data regarding the efficiency of Pfizer-BioNTech mRNA Pfizer-BioNTech COVID-19 vaccine in eliciting an antibody response in breastmilk >>>

2/6) This is a product of a fruitful collaboration between Lis Maternity and Women's Hospital, Tel Aviv @SouraskyMedCtr, and the research group of Systems Immunology and Immunotechnology, The @ShmunisR @TelAvivUni >>>

3/6) We describe a cohort of #breastfeeding women who received two doses of the @BNT162b2 @PfizerBioNTech vaccine. For all participants, we collected blood and #breastmilk samples at four time points post-#VaccinationCovid (days 7, 14, 28 35) and monitored >>>

4/6) the temporal dynamics of the vaccine-specific antibody response. We observed a rapid vaccine-specific antibody response in the blood and breastmilk, and the dynamics of the response in both compartments were synchronized>>>

5/6) In the blood, #spike -specific #Antibodies were dominated by #IGG , and in #breastmilk both #IGG and #IgA were elicited. The #breastmilk #antibodies showed #neutralization potential.
The generation of #vaccine -specific antibodies in #breastmilk can contribute>>>

6/6) to the protection of #breastfed #infants and may encourage breastfeeding women to receive the #mRNA -#vaccine . The preprint can be found here: disq.us/t/3veda2o
