Latest Update: September 8, 2021
COVID-19 Infection & Breastfeeding
All healthcare organizations recommend breastfeeding as it results in significant benefits for lactating parents and their infants. Lactating parents with COVID-19 symptoms or a diagnosis should continue to breastfeed while taking precautions such as hand washing and wearing a mask. Stable lactating parents should not be separated from their well infants at birth if they have COVID-19 symptoms or a diagnosis. Please visit the CDC for full guidelines.
Are COVID-19 Vaccinations Safe During Breastfeeding or Lactating?
Based upon the information that we have, we believe the vaccines are safe for use during breastfeeding. This is because no live viruses are contained in the vaccines. (The only two vaccines that are contraindicated for use during breastfeeding have live virus: Smallpox and Yellow Fever.) Indeed, multiple studies have found that COVID-19 specific antibodies pass in human milk, which are likely to protect children who receive their parents’ milk.
The vaccines use the mRNA-1273 of the SARS-CoV-2 virus, which are a minuscule part of the virus and cause the body to generate antibodies to protect against infection. One study has shown that no mRNA passed in the expressed milk of 7 mothers who pumped 4 to 48h after vaccination (Evaluation of Messenger RNA From COVID-19 BTN162b2 and mRNA-1273 Vaccines in Human Milk). If any mRNA were to pass in breastmilk, it would likely be degraded in the baby’s stomach. Vaccinated parents pass antibodies in their milk and last at least 3 months. These likely protect breastfed/chestfed children from infection. Local studies at the University of Rochester have found that these antibodies are both specific to COVID-19 and actively destroy the SARS-CoV-2 virus in milk from infected as well as vaccinated patients. No published studies to date have looked at the children’s immune response after ingesting this milk.
Our guidance is in line with all major healthcare organizations. Please check the CDC and FDA websites for updates. Specifically, see Vaccination of pregnant or lactating people for CDC guidance. You can also see Academy of Breastfeeding Medicine statement on considerations for COVID-19 vaccination in lactation.
COVID Vaccines While Pregnant or Breastfeeding: What You Need to Know
When Kate Ocon found out she was pregnant in November 2020, she thought about the COVID-19 vaccines on the horizon — and she thought she wouldn’t get one. A lot has changed in the few months since then.

In-person visits are being held with appropriate precautions. However, we are encouraging telephone visits when possible.
When you call for an in-person appointment, you will be asked some questions about how you are feeling and your travel history. If you come to the office, you will again be screened at the door, and at check in.
All Other Visits
All other visits will be done by video chat. If you are unable to video chat with Zoom, we will offer a telephone visit.
If you have or will schedule a non-essential telephone visit with our office, download ZOOM Cloud Meetings on your mobile device through the App Store, Google Play Store, or get the desktop version. You will receive a meeting ID to join the video call at your designated appointment time through MyChart.
Until further notice, our drop-in support group will be held online via Zoom. We want to ensure that you are still able to get the help you need during this time. However, we want to be cautious and continue to keep the health of the families we serve safe.
Zoom is an open forum video service that will allow you to discuss your concerns with the lactation consultant and other families from the safety of your home. Please register in advance for this meeting. After registering, you will receive a confirmation email containing information about joining the meeting.

Two recently released studies showed that few breastfed children had vaccine effects as a result of maternal vaccination. In one study of 180 women, Bertrand et al reported that more women had a temporary decrease in milk supply following the 2nd dose of Moderna vaccine as compared with mothers who received the Pfizer vaccine. In all cases, milk supply normalized within 72 hours. The most common effects in breastfed children were irritability, poor sleep and drowsiness.
In another study of 4,455 breastfeeding mothers, 1.7% of women reported a negative impact on breastfeeding and 7.1% reported any symptoms in their breastfed child following maternal vaccination. Mothers reporting symptoms in their children were more likely to have symptoms themselves.
