In response to the global coronavirus infectious disease 2019 (COVID-19) pandemic, several vaccines against severe acute respiratory syndrome coronavirus 2 have been developed. Although many infrequent side effects of COVID-19 mRNA vaccine have been reported, only a few cases of pancreatitis have been reported. ⋯ Acute pancreatitis can develop shortly after COVID-19 mRNA vaccination. Therefore, of great importance to differentiate acute pancreatitis when abdominal pain occurs after COVID-19 mRNA vaccination.

Case Reports
Multiple evanescent white dot syndrome following vaccination for COVID-19: A case report.
Multiple evanescent white dot syndrome (MEWDS) is an acute, usually unilateral, retinal disorder of unknown etiology that predominantly occurs in healthy young women. We report a case of bilateral asymmetric MEWDS that developed following the first vaccination for coronavirus-19 and worsened after a second vaccination. ⋯ Clinicians should be aware of potential adverse ocular events following similar vaccinations.

To facilitate the understanding of the interaction between severe acute respiratory syndrome coronavirus 2 causing the corona virus disease 2019 (COVID-19) and other pathogens causing respiratory system affection we investigated the effect of influenza vaccination on the incidence and severity of COVID-19 among members of staff working in the Bahrain Defense Force Hospital. All staff members working in the hospital between February 2020 and March 2021 were divided into 2 main groups based on whether or not they received influenza vaccination. None of the participants had received any of the COVID-19 vaccines throughout this time period. ⋯ Influenza vaccination also reduced total length of hospital stay (6.2 days vs 12.7 days, P < .05) and need for intensive care unit admission among the patients. Influenza vaccine reduces both the incidence of affection as well as the overall burden of COVID-19. This is of particular importance for people working in the healthcare field during the serious COVID-19 pandemic.

Comparative Study Observational Study
Comparative Effectiveness of BNT162b2 and mRNA-1273 Vaccines in U.S. Veterans.
The messenger RNA (mRNA)-based vaccines BNT162b2 and mRNA-1273 are more than 90% effective against coronavirus disease 2019 (Covid-19). However, their comparative effectiveness for a range of outcomes across diverse populations is unknown. ⋯ The 24-week risk of Covid-19 outcomes was low after vaccination with mRNA-1273 or BNT162b2, although risks were lower with mRNA-1273 than with BNT162b2. This pattern was consistent across periods marked by alpha- and delta-variant predominance. (Funded by the Department of Veterans Affairs and others.).
