on the actual subject of the tweet, it does seem remarkable.
Touch wood, my dad is through his bad spell. He's already tested negative on an LF, and apart from a bad spell on Thursday afternoon and yesterday morning, seems to be back to normal bar not being able to taste anything.
He's 65, had COPD in the past. Not unhealthy particularly now but still, smoked for 30 years etc. He's had both doses and really seems to have come out of the other side just fine. Not counting my chickens but hopefully it's an example of it working exactly as it should.
Not even 2 hours ago they were fine. Now, nothing!
