Article Synopsis
- - A study analyzed COVID-19 vaccine effectiveness among 521,206 emergency department visits and 139,548 hospitalizations between June 2021 and September 2022, focusing on adults with disabilities.
- - Of the encounters, only 2% had documented disabilities, but those individuals represent a significant portion of hospitalizations (12%).
- - The results showed that COVID-19 vaccines worked similarly for both disabled and non-disabled adults, highlighting the need for disabled individuals to keep their vaccinations current to protect against severe disease.
Article Synopsis
- Immunocompromised (IC) individuals face a higher risk of severe COVID-19 and have reduced vaccine effectiveness compared to non-immunocompromised (non-IC) individuals.
- A study analyzed emergency department visits and hospitalizations among IC and non-IC adults, finding that vaccine effectiveness was significantly lower in IC patients, particularly for those who received 3 doses of mRNA vaccines or 1-2 doses of viral-vector vaccines.
- Despite some protection from vaccines, the results indicate a pressing need for additional safeguards for IC adults, especially transplant recipients who showed the lowest vaccine effectiveness.

Article Synopsis
- - During mid-2022, the Omicron BA.5 variant was the dominant strain of SARS-CoV-2 in the U.S., and bivalent mRNA vaccines were introduced containing both the original virus strain and components targeting Omicron BA.4/BA.5.
- - A single bivalent booster was recommended for adults who had completed their primary vaccination and had not received a dose in the past two months, with effectiveness being evaluated from September to November 2022.
- - Results showed that the bivalent booster significantly reduced the risk of COVID-19-related emergency visits (56% effectiveness) and hospitalizations (59% effectiveness) compared to those unvaccinated or with only monovalent vaccines, highlighting the importance

Article Synopsis
- - During June-October 2022, the Omicron BA.5 sublineage dominated COVID-19 cases in the U.S., leading to the introduction of bivalent mRNA vaccines that target both the original virus and the Omicron BA.4/BA.5 variants.
- - A single bivalent booster dose was recommended for adults who had their last vaccination at least two months prior, and its effectiveness was evaluated from September to November 2022 compared to no vaccination or previous monovalent vaccinations.
- - Results showed that the bivalent booster significantly reduced emergency department visits and hospitalizations for COVID-19, with effectiveness increasing depending on how long it had been since the last monovalent dose was received.
Article Synopsis
- The Advisory Committee on Immunization Practices (ACIP) recommended a 3-dose primary series and subsequent booster doses of mRNA COVID-19 vaccines specifically for immunocompromised adults, acknowledging the rise of the Omicron variant.
- Data from a study indicate that the effectiveness of the vaccines varies, with a 36% effectiveness against hospitalization after 2 doses, increasing to 69% after 3 doses, but dropping to 44% after more than 90 days post-3rd dose during the Omicron variant period.
Everyone who serves in the military (and survives the experience) will eventually become a Veteran, and most will face the challenge of finding a civilian job. This paper investigates how contemporary Veterans experience the transition period between military exit and entrance into civilian life and how their own actions before separation shape their post-transition outcomes. We follow 35 servicemembers through the transition process, interviewing them before and several months after they left the military.

Methods: An analysis of 2012-2017 claims data from the IBM MarketScan Multi-State Medicaid Database for adult beneficiaries ages 18-64 years with mental and substance use disorder diagnoses (N= 1,603,066) identified telemedicine services by using procedure modifier codes and and diagnosis codes. Unadjusted trends in telemedicine use were examined, and multivariate regression models compared the prevalence and amount of telemedicine and in-person outpatient treatment received by rural (N=428,697) and nonrural (N= 1,174,369) beneficiaries and by diagnosis.
