More evidence that constructing SMART goals are the necessary next step after dreaming about what we want. And if a dream doesn’t fit into SMART format, then it’s a “wish” and something out of our control. Fun episode!

Overall mortality in unvaccinated individuals was roughly 50% HIGHER. The advantage held even after removing coronavirus-related deaths from the mix.

The study has been published in JAMA. YES, it is PEER-REVIEWED.

🧪🧵⬇️
Key Takeaways • In a French cohort, the incidence of all-cause mortality among those who received a first dose of an mRNA COVID vaccine was 0.4% after a median follow-up of 45 months, compared with 0.6% of those who were unvaccinated. • After standardizing characteristics between the two groups, all-cause mortality incidence was 25% lower in those who had received a COVID shot. • Vaccinated people were 74% less likely to die in a hospital because of COVID-19 compared with those who weren't vaccinated. Key Points Question Are COVID-19 mRNA vaccines associated with the long-term risk of all-cause mortality? Findings In this cohort study including 22.7 million vaccinated individuals and 5.9 million unvaccinated individuals, vaccinated individuals had a 74% lower risk of death from severe COVID-19 and no increased risk of all-cause mortality over a median follow-up of 45 months. Meaning These national-level results found no increased risk of 4-year all-cause mortality in individuals aged 18 to 59 years vaccinated against COVID-19, further supporting the safety of the mRNA vaccines that are being widely used worldwide. Abstract Importance While several studies have assessed the impact of COVID-19 vaccination on short-term mortality, none have compared long-term mortality by vaccination status, particularly in young individuals who are less likely to experience severe disease following SARS- CoV-2 infection. Objective To compare 4-year all-cause mortality in individuals aged 18 to 59 years vaccinated with the mRNA COVID-19 vaccine vs unvaccinated individuals. Design, Setting, and Participants This cohort study used data from the French National Health Data System for all individuals in the French population aged 18 to 59 years who were alive on November 1, 2021. Data analysis was conducted from June 2024 to September 2025. Exposure Exposure was defined as receiving a first mRNA dose between May 1 and October 31, 2021. Individuals who were unvaccinated by November 1, 2021, were assigned a random index date based on vaccinated individuals' vaccination dates. Main Outcomes and Measures Cox models weighted for sociodemographic characteristics and 41 comorbidities were used to estimate 4-year all-cause mortality. Time to event was censored at all-cause death, COVID-19 vaccination for unexposed individuals, or study termination on March 31, 2025. Complementary analyses were performed, including a comparison of the main causes of death available up to December 31, 2023. Follow-up began 6 months after the index date in both groups to address immortal time bias. Short-term mortality within 6 months after vaccination was assessed in a separate, independent study using adapted self-controlled case series models. Results A total of 22767 546 vaccinated and 5932 443 unvaccinated individuals were followed up for a median (IQR) of 45 (44-46) months. Vaccinated individuals were older than unvaccinated individuals (mean [SD] age, 38.0 [11.8] years vs 37.1 [11.4] years), more frequently women (11688 603 [51.3%] vs 2 876039 [48.5%]) and had more cardiometabolic comorbidities (2126 250 [9.3%] vs 464596 [7.8%]). During follow-up, 98 429 (0.4%) and 32 662 (0.6%) all-cause deaths occurred in the vaccinated and unvaccinated groups, respectively. Vaccinated individuals had a 74% lower risk of death from severe COVID-19 (weighted hazard ratio [wHR], 0.26 [95% CI, 0.22-0.30]) and a 25% lower risk of all-cause mortality (wHR, 0.75 [95% CI, 0.75-0.761), with a similar association observed when excluding severe COVID-19 death. Sensitivity analysis revealed that vaccinated individuals consistently had a lower risk of death, regardless of the cause. Mortality was 29% lower within 6 months following COVID-19 vaccination (relative incidence, 0.71 [95% CI, 0.69-0.731). Conclusions and Relevance In this national cohort study of 28 million individuals, the results found no increased risk of 4-year all-cause mortality in individuals aged 18 to 59 years vaccinated against COVID-19, further supporting the safety of the mRNA vaccines that are widely used worldwide.
