Important new study on #covid19 vaccines and *non-Covid* mortality, published over the holidays — looking at SAFETY of these vaccines.

(We already know they work to reduce #covid19 death)

sciencedirect.com/science/articl…

They matched people in a HUGE database - > 6 million recipients of the 3 most common vaccines (Pfizer, Moderna, J&J) and > 6 million people with similar age/race/gender/co-morbidities/neighborhood characteristics who had not been vaccinated.

They matched well (tables 1-3).

They then examined, using standard statistical techniques, the likelihood (“hazard ratio”) of:
1. any death other than Covid (the primary outcome of interest)
2. hospitalization for trauma (vaccines shouldn’t affect incidence of trauma!)

They found that being vaccinated was associated with:
1. LOWER risk of non-Covid death
2. SAME risk of trauma

(Tables 4-8: adjusted and unadjusted)

They were really careful in their interpretation. They do not conclude that covid vaccines reduce all-cause mortality. But it is clear that the vaccines do not INCREASE risk of death.

QED: safe

Please share when someone questions #vaccine safety based on small, poorly-designed, biased studies.

And then share @celinegounder’s excellent, empathetic piece
