Risk of long Covid declined over course of pandemic
The risk of long COVID has decreased due to vaccination and virus changes. Vaccination accounts for 70% of risk reduction. Long COVID affects 10% post-COVID individuals. Dr. Ziyad Al-Aly's study stresses vaccination's role.

The risk of long COVID has decreased over the course of the pandemic, with vaccination playing a significant role in this decline, according to researchers from Washington University School of Medicine in St. Louis. Their analysis, published in The New England Journal of Medicine, attributes 70% of the risk reduction to COVID-19 vaccination and 30% to changes over time in the virus's characteristics and improved detection and management of COVID-19. Despite the decrease in risk, long COVID remains a persistent threat, affecting about 10% of individuals who have had COVID-19. The study, led by Dr. Ziyad Al-Aly, emphasizes the importance of vaccination in reducing the risk of long COVID and highlights the evolving nature of the virus and its impact on different organ systems. While the overall risk has declined, the study underscores the continued importance of vaccination and ongoing efforts to understand and address the long-term effects of COVID-19.

New Covid Shots Recommended for Americans 6 Months and Older This Fall
The CDC urges all Americans 6 months and older to get new Covid-19 vaccines this fall. Data shows unvaccinated individuals faced severe outcomes. Vaccination is crucial to curb virus spread and protect vulnerable populations.
We know why some people got Covid while others didn't
Researchers conducted a study exposing volunteers to SARS-CoV-2, revealing distinct infection groups and unique immune responses. Specific immune cell responses and a protective gene were identified, offering insights for future treatments and vaccine development.
Highest Covid vaccination show steepest decline in pediatric asthma prevalence
High COVID-19 vaccination rates in states correlate with reduced pediatric asthma prevalence. A 10% increase in vaccination coverage led to a 0.36% decrease in asthma symptoms, indicating potential benefits beyond COVID-19. Further research is needed.
Study: Covid-19 reinfections likely have similar severity to original infection
A NIH-funded study on COVID-19 reinfections in 213,000 Americans found severe initial infections correlated with similar reinfection severity. Long COVID was more common after first infections. Lower albumin levels may indicate reinfection risk.
Covid-19 Infections and Cognitive Function
A study by Bas Weerman et al. explored COVID-19 infections' link to cognitive function using UAS data. Pre-pandemic cognitive tests predicted infection status, but subjective cognition did not. No negative association found post-baseline cognition, hinting at reverse causation influence.
