Bulgaria's vaccine battle: the mistrust driving COVID's surge

Fortunately, everything began with a bit of luck. I landed in Sofia, Bulgaria's capital, on a late November Sunday afternoon. The weather was mild and sunny. After checking into my hotel, I went for a walk in the city centre with my filming kit. 'I'm not a killer of grandpa and grandma.' Scarcely five hundred meters from the hotel, I stumbled on around two hundred people noisily chanting and shouting. Among them were children and elderly people; whole families banging on drums and waving big Bulgarian flags. I approached and asked them what they were protesting about.
