COVID19 SARS Vaccinations: Systemic Allergic Reactions to SARS-CoV-2 Vaccinations
Completed
Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: * To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a... Read More

A Study to Learn About How a New Pneumococcal Vaccine Works in Infants
Recruiting
The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs in infants when compared to the pneumococcal vaccines that are currently in use, 20vPnC (Prevnar 20®) or another licensed pneumococcal vaccine. To ensure that the new vaccine (PG4) stays stable, it is placed in a liquid mixture of sterile water and other substances (a solution). This study will also test if there is a difference in the safety and... Read More
