Study: Vaccinated >2x Higher Risk of Retinal Vascular Occlusion

Quite a few websites have already covered this but it is worth repeating. An article by Jing-Xing Li et al titled “Risk assessment of retinal vascular occlusion after COVID-19 vaccination” published on 2 May 2023 has found that individuals who have received COVID-19 vaccines have a higher risk (2.19x) of retinal vascular occlusion 2 years after vaccination compared to the unvaccinated.


The study examined data for only three so-called vaccines: BNT162b2 (Pfizer), mRNA-1273 (Moderna) and Ad26.COV2.S (Johnson & Johnson).


The authors used data from the TriNetX network. After excluding individuals with confirmed COVID-19, or retinal vascular occlusion diagnosis 6 months prior, and those on anti-platelets and anti-coagulants, amongst other drugs, 745,041 vaccinated and 3,874,458 unvaccinated individuals were included in the analysis. This is a large sample size by any standard.


The study examined two periods 12 weeks and 2 years after vaccination. As one can see from Table 3 reproduced below, the risk is significantly increased 12 weeks after vaccination. This, disturbingly, does not improve after 2 years.

A glance at the stratified analysis as shown in Table 2 reproduced below, one can see the risk is increased across the board. It seems worse for those aged 65 years and older compared to those who are younger. Male and female seem comparable. African-Americans seem to be at less risk compared to White and Asians.
