Study of the Safety of a 21-valent Pneumococcal Conjugate Vaccine in Healthy Infants From Approximately 2 Months of Age
Recruiting
This study is a Phase 3, randomized, modified double-blind study which aims to document the safety profile of the PCV21 vaccine (investigational pneumococcal vaccine) compared to a licensed 20-valent pneumococcal conjugate vaccine in infants aged from approximately 2 months (42 to 89 days). The study duration per participant will be up to approximately 19 months. The study vaccines (either PCV21 or 20vPCV) will be administered at approximately 2, 4, 6 and 12 to 15 months of age. Routine pediatr... Read More

B Cell and Antibody Response to Seasonal Influenza Vaccines in Younger and Older Adults
Recruiting
This study will examine how various FDA-approved seasonal influenza vaccine types, used in a manner consistent with their approved use, impact the characteristics of influenza specific antibodies in humans, and how these responses differ based on age and prior immunization history.

A Study to Evaluate VXA-CoV2-3.3 COVID-19 Vaccine Against Currently Approved/Authorized mRNA COVID-19 Injectable Booster Vaccine in Adults Previously Immunized Against COVID-19 Infection
Recruiting
The primary objective of the study is to determine the relative efficacy of the investigational oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine tablet VXA-CoV2-3.3 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19). In order to represent a more recently circulating SARS-CoV-2 variant, the main study endpoints will now evaluate the VXA-CoV2-3.3 (KP.2 strain) vaccine, and not the VXA-CoV2-3.1 (XBB.1.5 strain)...

Developing and Evaluating a Novel Approach to Improve HPV Vaccination Coverage Among High-risk, Under-immunized Adults Via the Emergency Department
Recruiting
To determine if the emergency department (ED) setting offers a viable space for improving HPV vaccination coverage among 18 to 45-year-old adults who have not yet received human papilloma virus (HPV) vaccination or who did not complete the vaccine series. This study will develop, pilot and evaluate an ED-based HPV vaccination protocol and program for ED patients aged 18-26 (for whom catch-up HPV vaccination is routinely recommended by the CDC) and separately for patients aged 27-45 (for whom it...

Live Attenuated Influenza Vaccine As a Nasal Model for Influenza Infection
Recruiting
The purpose of this study is to develop a nasal model for influenza infection using the live attenuated influenza vaccine (LAIV). The investigators will administer LAIV to healthy adult volunteers in order to simulate influenza infection, and obtain nasal specimens to measure influenza virus and inflammatory/immune responses. In a subset of participants, cystic fibrosis transmembrane conductance regulator (CFTR) function will also be evaluated via measurement of nasal potential difference (NPD)
