The comment on that page:

> The method (eSupplement) states the study was conduce between February and October 2020. That surprises me because the vaccinations being studied were not available to the public for that entire period. The first dose outside a clinical trial was given in Queens, New York on December 14 that year. Before this, they were only available as part of trials which excluded lactating individuals.

One of the authors has responded to the comment:

> The Supplement section of the letter states that the study was conducted from February to October 2020. The year reported was an error; the study was conducted in 2021. The Journal is in the process of correcting this error.

Seems likely that this is a typo which should have said 2021.

Do you have access to the full text version? It would be nice to know the number of participants and the concentration of mRNA in the milk.

Some details on this Twitter thread: https://twitter.com/VikiLovesFACS/status/1574663804801388547

To me, the concerns this raises have less to do with breastfeeding infants and more to do with biodistribution of the mRNA after vaccination -- in theory it's not "supposed" to be found anywhere other than the muscle tissue around the injection site.

Takeaway from that twitter thread:

> The authors conclude that the very low levels found suggest that mRNA COVID vaccination is safe during breastfeeding, and this is in line with the findings of other safety in breastfeeding studies,

It would be nice to have a quote from the research article.

> Assuming this mRNA was active vaccine, how much milk would we need to make a dose? For a 100 mg dose of Moderna, about 50 bathtubs. For a 30 mg dose of Pfizer, only 15. Or for a pediatric dose (10mg), only 5 bathtubs.

Other user>> if it work via ingestion we would not need to inject them (i would be damn glad for it :) :) )
