Can we learn more about what happens when lactating persons receive an mRNA-based COVID-19 vaccine?
Measuring Protein in Breast/Chest Milk
The objective of this research is to determine whether vaccine-derived protein from mRNA-based COVID-19 vaccination leads to detectable protein in breast/chest milk. We will use a method called SIMOA digital ELISA to detect these proteins in samples from days one through fourteen following vaccination.
You will be asked to collect milk samples at multiple timepoints:
- Before you receive your next COVID vaccination
- Immediately after you receive your COVID vaccination
- For the next 2 weeks after your vaccination
You are eligible if you are:
- Currently lactating (breastfeeding/chest feeding/pumping)
- Age ≥ 16 years
- Planning to receive an mRNA-based COVID-19 vaccination while lactating
- Willing to collect milk samples over a 3-week period
What are the short and long-term effects of COVID-19 vaccination in pregnancy?
Information related to COVID-19 vaccines is rapidly evolving. A lack of data on COVID-19 vaccines in pregnant women/individuals makes it challenging for Canadian families to make informed decisions about COVID-19 vaccination.
We are conducting a research study at participating hospitals located across Ontario to measure the short and long-term effects of COVID-19 vaccination in pregnancy.
You are eligible if:
- You are currently pregnant AND
- You plan to receive a COVID-19 vaccine dose in your current pregnancy AND
- You plan to deliver at Kingston General Hospital.
