The Claim
In lactating individuals, COVID-19 vaccination is associated with minimal changes in human milk composition, including no detectable alterations in lipid or metabolite profiles and fewer than 13 proteins significantly changed, suggesting a limited biochemical impact compared to the effects of natural SARS-CoV-2 infection.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Getting a COVID-19 vaccine while breastfeeding doesn’t really change the makeup of your milk — no big shifts in fats, nutrients, or proteins — so it probably doesn’t affect your milk much at all.

What the research says
1 studyThe study shows that getting a COVID-19 vaccine causes very few changes in breast milk, while getting infected with the virus causes many more. This supports the idea that the vaccine is safe for breastfeeding moms and babies.
