The Infant Vaccine Biorepository is an observational study to better understand how long the protection against infection or from a vaccine lasts when transferred through the placenta (from mother to baby). We will research infections such as influenza (the flu), pertussis (Whooping Cough), and SARS-CoV-2 (COVID-19). As part of the study, you will be asked to collect your baby’s blood sample at home. The consenting parent will also have the option to test the device. If that consenting parent is the parent that gave birth to the infant enrolled in the study, they will have the option to collect and send in their blood sample. You will be asked to collect a blood sample from your baby at home at 3-5 months-old, 6-8 months-old, and 9-12 months-old, using a device called the Tasso-SST. This is blood collection device that will take blood from the smallest blood vessels (the capillaries).

This study is collecting samples and clinical data from individuals who are vaccinated against, infected, and/or suspected to have monkeypox. This study is currently enrolling participants, including pregnant and lactating individuals

This study is assessing whether COVID-19 vaccines reduce SARS-CoV-2 transmission within households and how readily SARS-CoV2 transmits to household members in an effort to determine better quarantine measures. This study is currently enrolling participants.

This study is comparing the immunogenicity and safety of an investigational yellow fever vaccine with the previously approved YF-VAX vaccine. The main purpose of the study is to determine if the study vaccine is safe and creates comparable immune responses to that of the YF-VAX vaccine. This study is currently enrolling.
