Great interview, but I disagree on some of Jay's views like the GBD policy. Limited lockdowns 'were' our only defence against covid-19 before vaccines became available, keeping the most vulnerable in isolation (for an unspecified period of time) wasn't practical if a large part of the population (eg. 40%+) were to be infected. They would still be infected as the general public do not really understand the risks around transmission and also make mistakes (leading to transmission). <br><br>One problem, as we have seen, is the that variants of covid-19 will continue to bypass some of the vaccine's efficacy, these variants have emerged from places like Brazil, India, South Africa where the original virus grew unchecked very quickly against unvaccinated or lockdown-free populations. We need vaccines that also deal with the latest variants (eg. Omicron) so governments don't get forced to panic again (as hospital cases put healthcare systems under great stress) and implement more lockdown measures. The companies (Pfizer etc) know it can be done in weeks, I've seen some of the interviews.,(reply>), They address this.
