Evaluating real-world COVID-19 vaccine effectiveness using a test-negative case-control design.

It is important to assess if clinical trial efficacy translates into real-world effectiveness for COVID-19 vaccines. We conducted a modified test-negative design (TND) to evaluate the real-world effectiveness of three COVID-19 vaccines. We defined cases in two ways: self-reported COVID-19-positive tests, and self-reported positive tests with ≥1 moderate/severe COVID-19 symptom.

COVID-19 Vaccinations in Pregnancy: Comparative Evaluation of Acute Side Effects and Self-Reported Impact on Quality of Life between Pregnant and Nonpregnant Women in the United States.

Objective: The objective of this study was to describe the acute side effects experienced by pregnant women who received a coronavirus disease 2019 (COVID-19) vaccine in the United States and to compare their experience to nonpregnant women of similar age.

Study Design: Adults who received a COVID-19 vaccine in the United States were invited via social media to enroll in an online, longitudinal, community-based registry ( www.helpstopCOVID19.

How frequent are acute reactions to COVID-19 vaccination and who is at risk?

Introduction: Our objective was to describe and compare self-reported side effects ofCOVID-19 vaccinesin theUSA.

Methods: Aweb-basedregistry enrolled volunteers who received a COVID-19 vaccine between March 19-July 15, 2021. We collected self-reported short-term side effects, medical consultation, hospitalization, and quality of life impact following completed vaccination regimens (Pfizer, Moderna, J&J).

Identification of a Vulnerable Group for Post-Acute Sequelae of SARS-CoV-2 (PASC): People with Autoimmune Diseases Recover More Slowly from COVID-19.

Purpose: Evidence is emerging that a significant percentage of COVID-19 cases experience symptom persistence beyond 30 days and go on to develop post-acute sequelae. Our objective was to compare the risk for COVID-19 symptom persistence by self-reported use of medications for autoimmune disease among participants of an on-line COVID-19 registry.

Patients And Methods: A community-based online survey collected weekly data on COVID-19 symptom presentation.

Associations of Father and Adult Male Presence with First Pregnancy and HIV Infection: Longitudinal Evidence from Adolescent Girls and Young Women in Rural South Africa (HPTN 068).

This study, a secondary analysis of the HPTN 068 randomized control trial, aimed to quantify the association of father and male presence with HIV incidence and first pregnancy among 2533 school-going adolescent girls and young women (AGYW) in rural South Africa participating in the trial between March 2011 and April 2017. Participants' ages ranged from 13-20 years at study enrollment and 17-25 at the post-intervention visit. HIV and pregnancy incidence rates were calculated for each level of the exposure variables using Poisson regression, adjusted for age using restricted quadratic spline variables, and, in the case of pregnancy, also adjusted for whether the household received a social grant.

Factors associated with unmet need for modern contraception in post-conflict Liberia.

We examined the association between intimate partner violence and unmet need for modern contraception in post-conflict Liberia. This is a secondary analysis of data collected using the Priorities for Local AIDS Control Efforts (PLACE) method. Data from 499 sexually experienced young women (aged 14-25) in Montserrado County, Liberia were examined.

Acceptability of male circumcision for prevention of HIV infection among men and women in Uganda.

In the last decade, three randomized controlled trials in Kenya, South Africa, and Uganda have shown that medical male circumcision (MMC) reduces the sexual transmission of HIV from women to men. Objectives of this assessment were to measure acceptability of adult MMC and circumcision of children to inform policies regarding whether and how to promote MMC as an HIV prevention strategy. This mixed-method study, conducted across four Ugandan districts, included a two-stage household survey of 833 adult males and 842 adult females, focus group discussions, and a health provider survey.
