COVID19 Clinical Trials in Pasadena, CA

The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 9000 participants will be assigned into 1 of 4 vaccination groups (Group A, B, C or D) by chance. Cohort 1: Around 4500 participants will be assigned by chance to one of the following: Group A:Influenza and COVID-19 combination A vaccine, given at the same time in the right arm and placebo (an injection consisting of just salt water and no medicines in it) in the left arm. Group B: COVID-19 vaccine, given at the same time to the right arm and licensed influenza vaccine in the left arm. Cohort 2: Around 4500 participants will be assigned by chance to one of the following: Group C: Influenza and COVID-19 combination B vaccine, given at the same time in the right arm and placebo in the left arm. Group D: COVID-19 vaccine, given at the same time in the right arm and licenced influenza vaccine in the left arm. All participants will receive 2 injections as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, the study will compare participant experiences when they receive a combined vaccination to when they receive separate vaccinations. This will help understand if the study medicine is safe. Read Less

The primary objective of this study is to determine the vaccine effectiveness of 2 doses of Pfizer-BioNTech BNT162b2 vaccine against COVID-19-associated hospitalization. There will be a large retrospective database study using two parallel study designs: a test-negative case-control design and a retrospective cohort design.

To compare the results obtained by analysis of a self-collected anterior nasal (AN) swab as part of the Labcorp COVID-19+Flu+RSV Test Home Collection Kit to a healthcare provider (HCP)-collected AN swab in patients with symptoms of viral respiratory infection consistent with influenza A (Flu A), influenza B (Flu B), respiratory syncytial virus (RSV) and/or SARS-CoV-2 (C-19).

This is an observational cohort study to evaluate real-world vaccine effectiveness and durability of Moderna COVID-19 vaccine among a diverse population at Kaiser Permanente Southern California (KPSC). The primary objective of this study is to evaluate the vaccine effectiveness (VE) of receipt of Moderna COVID-19 vaccine in preventing SARS-CoV-2 infection and severe COVID-19 disease. SARS-CoV-2 infection will be defined as a positive antigen test result as well as a positive molecular diagnostic test among symptomatic or asymptomatic participants or a COVID-19 diagnosis code. Severe COVID-19 disease will be defined as COVID-19 hospitalization or mortality. Read Less
