LOS ANGELES: Researchers did not find evidence for the existence of Pfizer or Moderna Covid-19 vaccine in breast milk in a small study, indicating that prevention of safe MRNA during lactation.
This study, published in Jama Pediatrics Journal, offers the first direct data from vaccine security during breastfeeding and can eliminate concerns between those who have rejected vaccinated or stopping breastfeeding due to fears that vaccination can change breast milk.
Researchers at the University of California, San Francisco (USCF) in the US analyzed the ASI seven women after they received the Pfizer vaccine and Moderna MRNA, and did not find a trace of prevention.
Previous research has shown that the vaccine with MRNA inhibits viral transmission which causes Covid-19.
The World Health Organization (WHO) recommends that nursing people vaccinate, the researchers noted.
According to the breastfeeding treatment academy, there is a slight risk of vaccine or mrna nanoparticles entering the breast tissue or transferred to milk, which can theoretically influence the immune baby, he added.
“The results of strengthening the current recommendations that the MRNA vaccine is safe in lactation, and breastfeeding individuals who receive covid vaccines should not stop breastfeeding,” said the author’s study according to Stephanie L Gaw, assistant professor at UCSF.
“We did not detect the vaccine related to MRNA in one of the samples of milk tested,” said the main author of Yarden Golan’s writer, a postdoctoral colleague at UCSF.
This study, conducted from December 2020 to February 2021, provides experimental evidence of the safety of the use of mRNA-based vaccines during lactation.
The average age of the mother in this study was 37.8 years and their children ranged at the age of one month to three years.
Milk samples are collected before vaccination and at various times of up to 48 hours after vaccination.
The researchers found that there were no samples that showed the level of mRNA vaccines that could be detected in any milk components.
The study was limited by small sample size, the researchers noted, added that further clinical data from a larger population was needed to estimate the effect of better lactation vaccination.
