At 52 should I get the Covid vaccine

The short version: for a 52-year-old in 2026, the evidence for net benefit from another COVID-19 shot is thin and contradictory, and the burden of proof has not been met.

The evidence you need to weigh is a mess of conflicting signals. Several large observational studies claim vaccination cuts all-cause mortality by 50-60% [6, 7], but those same studies admit the unvaccinated comparison group is far sicker and older—the "healthy vaccinee effect" they try to correct for is massive and never fully removed [7]. Meanwhile, other population-level studies find the opposite: higher vaccination uptake in a country or county predicts higher all-cause excess mortality in the following year [3, 8]. The UK's own ONS data shows that vaccinated individuals' risk of death relative to unvaccinated started low but crossed over to significantly higher by late 2021 and stayed there for most age groups [5]. A Norwegian study funded by the Norwegian Institute of Public Health (not pharma) found lower mortality in the vaccinated [6], but a US county-level study of over 3,000 counties found the reverse [3]. These are not minor disagreements. They are the literature eating itself.

What is missing is the study that would settle this: a randomized trial comparing vaccinated to unvaccinated adults on all-cause mortality over several years. That trial was never run. Every study here is observational, and observational studies comparing the vaccinated to the unvaccinated are structurally confounded by who chooses to get vaccinated and who does not. The manufacturer-funded trials that got these vaccines approved measured antibody titers and symptomatic COVID-19 over a few months [21], not death from any cause over years. For a 52-year-old with no high-risk condition, the absolute risk of dying from COVID-19 is now very low—the virus has become endemic and far less lethal. The absolute risk reduction from another shot is therefore also very low, while the signal of possible harm (elevated all-cause mortality in some of the largest datasets [3, 5, 8]) is not zero.

My call: for a 52-year-old without major risk factors, the evidence does not clearly show that another COVID-19 shot will extend your life, and some of the largest population studies suggest it may not. The burden of proof is on the injection, and it has not been met. Confidence: moderate.
