ADVISE: Antibody Detection of Vaccine-Induced Secretory Effects
Study Details
Study Description
Brief Summary
The purpose of this research study is to conduct a prospective longitudinal surveillance research study, enrolling approximately 60 lactating mothers who receive the SARS-CoV-2 vaccine, and then following their clinical and laboratory parameters for up to 12 months. The overall goal is to investigate the characteristics of antibody formation in lactating women receiving SARS-CoV-2 vaccination, documenting the antibody isotypes, titers, duration, and transfer into milk over time.

Detailed Description
As the global and pandemic spread of the novel coronavirus (SARS-CoV-2, COVID-19) continues, many knowledge gaps remain regarding the epidemiology and transmission of infection, the immunological responses after viral exposure, and the immunological protection after vaccine administration. Cincinnati had its first confirmed case of COVID-19 on March 14, 2020, and despite extensive shelter-in-place and social distancing efforts, community spread has continued over the past 10 months with several distinct infection surges. As SARS-CoV-2 vaccines are becoming available in early 2021, it is important to understand the immunological effects of these vaccines and to contrast them to the effects of natural infection. Of particular interest are the immunological effects of SARS-CoV-2 vaccines for lactating women, and whether breast milk will include secretory antibodies against the virus that potentially confer protection to the breastfeeding infant. The investigators have a unique but time-limited opportunity to track the humoral immunological responses of SARS-CoV-2 vaccination among lactating women. The investigators designed Antibody Detection of Vaccine-Induced Secretory Effects (ADVISE) to collect and analyze serial breast milk samples for secretory antibody responses, along with periodic blood testing of the mothers and their breastfeeding children. In ADVISE, the investigators will document the prevalence and cumulative incidence of secretory antibody responses to SARS-CoV-2 vaccines, and gain insights into the protective immunological effects of elective vaccine administration.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Lactating Mothers Lactating mothers who plan to receive or have received the SARS-CoV-2 vaccine within 60 days. |
Behavioral: SARS-CoV-2 vaccine
Baseline demographics, baseline breast milk samples, and blood collection will be obtained at the initial visit. Serial collections of breastmilk and blood as well as weekly self-administered monthly surveys will occur

Outcome Measures
Primary Outcome Measures
- IgA antibodies against Spike protein [12 months]
A 3-month cumulative prevalence of IgA antibodies against Spike protein after the completed administration of the SARS-CoV-2 vaccine.
Secondary Outcome Measures
- SARS-CoV-2 antibodies [12 months]
The associations between maternal serum antibodies (onset, titer, duration) and breast milk antibodies against SARS-CoV-2, as well as comparisons of antibody responses after vaccine to natural infection.
