"In February, the World Health Organization (WHO) warned that "there are still critical unknowns regarding the efficacy of vaccination" including combating variants of SARS-CoV-2; the duration of protection following vaccination; the timing of booster doses and whether vaccination offered protection against asymptomatic infection."

Good to see the WHO acting responsibly for a change.

I have no doubt that the lock out of international air travel is what has kept us & New Zealand infection & death rates to a minimum.

It is also probable that state boarder closures is what has prevented that idiot in Victoria infecting the whole country, & actually helped keep Victoria's problems to a level they have been able to contain.

While they would have to hold me down, kicking & screaming to stick one of their rapidly contrived concoctions into my blood, an international COVID immunity passport could be a very good thing. If it does nothing other than reduce international travel by 50%, or hopefully much more, it will help reduce a whole host of ill effects that are involved in such travel.

While I realise this would be just a small step towards keeping the peasants on the manor, it may do more good than harm.
