Breastfeeding inhibits response to rotavirus vaccination.

Not surprising, as breastfeeding is protective against rotavirus infection as well. Since this is an oral vaccine, this does make sense, and now I'm wondering why this is "new" news and why this hadn't been previously documented. Or is it because the whole thing is a giant experiment, and we learn as we go. I wonder how many breastfeeding moms agree to the rotavirus vaccine or even have a clue about this.

Interpretation: The lower immunogenicity and efficacy of rotavirus vaccines in poor developing countries could be explained, in part, by higher titers of IgA and neutralizing activity in breast milk consumed by their infants at the time of immunization that could effectively reduce the potency of the vaccine. Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated.

makes sense... I'm concerned though that health organizations will start telling those moms to formula feed and inhibit breastfeeding.

Considering the dangers of bottlefeeding in countries with poor water quality, that would be crazy advice.

Does anybody have a full copy of this article? I'm curious what they mean in the abstract about "delaying breast-feeding at the time of immunization." For how long, exactly? And is there any science behind whatever chunk of time is prescribed? Or is that what the authors believe "should be evaluated?"
