Mate of mine, both parents in hospital recently, and only just a few days ago, both were basically at deaths door with the virus. Doctors had told him his da had the highest levels of the virus he'd seen so far. Was told his mother was basically on her own if her condition deteriorated. Both fully vaccinated. Got told today that both are now on the mend and don't need oxygen or hospital treatment anymore. Essentially, doctors said that if both weren't vaccinated, and if they'd caught the virus in the first wave when little was known treatment wise, then they'd both have died in the first 24 hours.
You hear things like this first hand from people you know, and yet there are dickheads that refuse a vaccine.
