I live in Spain, a couple of hours east of Gibraltar. I haven’t heard anything about this and when I did a search the latest article I could find was from August 2nd, and that was an article saying that cases were dropping.
You’re correct. Average new cases peaked at a whopping 31 per day on July 21st and have been dropping steadily since then. Current average is 24 cases per day. Only 1 COVID-19 death since March. Current active cases in the country is 295.
Prior to vaccinations, Gibraltar racked up one of the highest deaths per 1 million population in the entire world at 2,821. Since the vaccination campaign, only 1 COVID-19 death has happened. If this is the anti-vaxxer example of how bad the vaccines are, their narrative is truly bankrupt.
