Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

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.

The goal of this pilot clinical trial is to determine feasibility and explore whether financial incentives paid to primary care patients for completing colorectal cancer screening increase completion of colorectal cancer screening. The main questions it aims to answer are: - Do patient financial incentives for completing colorectal cancer screening increase screening completion? - Does a patient financial incentive for colorectal cancer screening offered alongside patient financial incentives for COVID-19 and flu shots increase completion of those shots? Participants who are due for colorectal cancer screening will receive telephone outreach from primary care staff who will offer a stool-based colorectal cancer screening. Participants will be randomly assigned to either Group 1 or Group 2. Group 1 participants will be offered financial incentives for completing COVID-19 and flu shots within 2 months of enrollment. Group 2 participants will be offered financial incentives for completing a COVID-19 shot, a flu shot, and colorectal cancer screening within 2 months of enrollment. Researchers will compare to see if completion of a COVID-19 shot, a flu shot, and colorectal cancer screening is different between the two groups.
