So, the dilemma among the chattering classes this week is whether or not to pre-book a Summer holiday now, in order to get somewhere decent, or not. Since we're supposed to be releasing all lock-down restrictions on June 21st then is it reasonable to think that booking a holiday for July should be OK? Of course doing that is making the bet that everything will go according to plan, something that hasn't happened so far for pretty much anything apart from the vaccination program, which seems to be just about on track. There are a number of risks that need to be assessed, these include,
- Virus variant emerges and escapes the vaccine (putting us back to square one)
- Vaccine supply is interrupted or reduced somehow
- Vaccine efficacy isn't as high as we thought, or transmission continues at a high rate
- Antivaxxers are sufficiently numerous to prevent herd immunity
- Immunity window for vaccines is much shorter than we thought
