Breastfeeding and the COVID vaccine?
In the US, breastfeeding people have the option to receive the Pfizer-BioNTech and Moderna COVID vaccines. Initially, this was debated due to the lack of robust data to support safety and efficacy in this special people group. Now, leading experts agree the benefit of the vaccine greatly outweighs the risk of COVID disease.
In my practice, I am recommending my front-line health care individuals get vaccinated against COVID-19 as recommended by the ACIP, including those who are breastfeeding. I have no preference between these two vaccines, either one has similar makeup and safety profiles. Plus, I cannot think of a biological reason to “pump and dump” or avoid breastfeeding for any duration of time after receiving the vaccine.
The mRNA vaccines do not contain any live viral particles that could infect the breastmilk. Plus, just like we see after other vaccinations, it is likely that vaccinating a breastfeeding person will transmit protective antibodies to the feeding infant.
Here are some resources that may help the discussion with your personal physician:
From ACOG: “Theoretical concerns regarding the safety of vaccinating lactating individuals do not outweigh the potential benefits of receiving the vaccine. There is no need to avoid initiation or discontinue breastfeeding in patients who receive a COVID-19 vaccine.”
From the CDC: “mRNA vaccines are not thought to be a risk to the breastfeeding infant. A lactating person who is part of a group recommended to receive a COVID-19 vaccine (e.g., healthcare personnel) may choose to be vaccinated.”
From the ABM: “There is little biological plausibility that the vaccine will cause harm, and antibodies to SARS-CoV-2 in milk may protect the breastfeeding child.”
As more data becomes available, all these leading experts will offer revisions to their recommendation if needed. As always, I’ll keep you posted!
