Pfizer COVID jab 'linked to major eye damage and sight loss'

A Turkish study indicates potential eye damage linked to the Pfizer COVID-19 vaccine.

Study reveals Pfizer vaccine may cause serious eye damage

Researchers in Turkey have found that the Pfizer COVID-19 vaccine could be linked to serious changes in the cornea, the eye's outermost layer. The study involved 64 participants whose corneal structure was analyzed before and after receiving the vaccine. Key findings show an increase in corneal thickness and variations in the number of endothelial cells, which may heighten the risk of conditions like corneal swelling and vision loss. While the study does not advise against vaccination, it emphasizes the need for ongoing monitoring of eye health, particularly in individuals with prior eye issues.

Key Takeaways

✔️

Study identifies eye damage risk associated with Pfizer vaccine.

✔️

Corneal changes noted include increased thickness and lower cell density.

✔️

Potential long-term effects may include serious vision issues.

✔️

Pre-existing conditions could exacerbate the risk of eye damage.

✔️

Pfizer maintains a positive benefit-risk profile for the vaccine.

✔️

Continued research on vaccine safety is vital for public health.

"The endothelium should be closely monitored in those with a low endothelial count."

This statement highlights the need for vigilance regarding eye health post-vaccine.

"Patient safety is paramount and we take any reports of adverse events very seriously."

Pfizer emphasizes the importance of addressing safety concerns related to their vaccine.

"The benefit-risk profile of the vaccine remains positive for all authorized indications."

Pfizer asserts the overall safety of their vaccine while acknowledging concerns.

"Changes in corneal health may lead to serious vision issues in the future."

Researchers warn about the potential long-term consequences of observed corneal changes.

This study shines a light on potential side effects of the Pfizer vaccine that had not been widely discussed. As vaccination campaigns continue globally, understanding possible adverse effects is crucial for public safety. The warning about corneal health raises concerns among individuals, especially those with previous eye conditions. Scientists note that while immediate harm to vision is unlikely, the long-term implications could be significant. The call for continual monitoring reflects a necessary caution in the ongoing evaluation of vaccine safety.
