Columbus, Ohio - February 10, 2026 - A recent case series from the Ohio State University Wexner Medical Center is underscoring the continued, and significant, risk COVID-19 poses to unvaccinated individuals, particularly those requiring critical care. The study, published Monday on the pre-print server medRxiv, details a cohort of ten patients admitted to the hospital's critical care unit with active COVID-19 infections. Strikingly, nine of those ten patients were unvaccinated against the virus.

The findings, while not statistically significant due to the small sample size, align with a growing body of evidence demonstrating the protective effects of vaccination against severe disease, hospitalization, and death. The patients in the Ohio State study ranged in age from 26 to 89, indicating that susceptibility to severe COVID-19 isn't limited to older demographics, although age undoubtedly remains a significant risk factor.

Dr. Christopher Campbell, the lead author of the study, emphasizes the persistence of the threat, stating, "We're seeing that even though we have vaccinations, COVID-19 is still posing a risk." He points out that while vaccines aren't foolproof - breakthrough infections do occur - the vast majority of severe cases continue to occur in those who have not received the primary vaccine series, or crucially, haven't received recommended booster doses.

The initial rollout of COVID-19 vaccines in late 2020 and early 2021 was met with high demand and demonstrable success in reducing severe illness. However, vaccination rates plateaued throughout 2022 and 2023, and booster uptake has lagged considerably behind initial vaccination numbers. Public health officials have repeatedly expressed concern that waning immunity, combined with the emergence of new variants, is contributing to a resurgence of severe cases, particularly during the colder months.

Experts suggest several factors contribute to the lower booster rates. Vaccine fatigue, misinformation campaigns, and a perceived decline in risk have all played a role. Some individuals believe that because they completed the initial vaccine series, they are adequately protected, failing to recognize the importance of boosters in maintaining strong immunity. The constant evolution of the virus, necessitating updated booster formulations targeting new variants, also adds to public confusion. The current boosters, updated in late 2025 to specifically target the XBB.1.5 and its descendant strains, have proven highly effective against currently circulating variants.

This Ohio State study serves as a stark reminder of the real-world consequences of vaccine hesitancy. While mild cases of COVID-19 may be manageable at home, critical care admission places a tremendous strain on healthcare resources, diverts attention from other patients, and carries a significantly higher risk of long-term health complications, or even death. The cost of critical care is also substantial, placing an additional burden on the healthcare system and potentially impacting individual families.

Beyond the immediate health impacts, the continued presence of severe COVID-19 cases has implications for broader economic stability. Workforce disruptions due to illness and hospitalizations can hinder productivity and exacerbate existing labor shortages. Maintaining a healthy and productive workforce requires a proactive approach to disease prevention, and vaccination remains a cornerstone of that strategy.

Dr. Campbell's call for vaccination and boosting is echoed by public health agencies worldwide. "It's crucial for people to get vaccinated and boosted to protect themselves against severe illness," he stresses. Public health campaigns are being ramped up to address vaccine hesitancy and promote booster uptake, focusing on clear communication of the benefits of vaccination and debunking common myths. Incentives, such as paid time off for vaccination and booster appointments, are also being explored in some regions. The hope is that renewed awareness and accessibility will encourage more people to protect themselves and their communities from the ongoing threat of COVID-19.
