Conjunctivitis was one of the adverse reactions for those who were vaccinated with the Covid-19 'vaccine'. The CDC's VAERS database (Vaccine Adverse Event Reporting System) has records of adverse events for all vaccines for the past 30 years, althought it only captures about 1% of all events. But, as it stands now, Covid 'vaccines' account for 25% of all cases of conjunctivitis reported to the CDC. So even though the 'vaccine' has only been around for a short time, one out of every 4 cases in VAERS was reported after a Covid 'vaccine'.

They just take adverse events from VAERS and call it a new version of Covid because the suppression of immune system function often provides 'Covid-like' symptoms anyway.
