If eradicated, why are you still rolling out COVID-19 vaccines?
This is idiotic.
Let me explain what happened in NZ maybe this will help.
NZ by the way, is part of planet Earth, and we have travellers that leave NZ and travellers that come into NZ.
When the pandemic first started, Covid had spread pretty much everywhere.
As with most countries, we sent messages to NZer's abroad that NZ will soon go into lockdown and gave them some time to come home.
Once they came home, we did go into lockdown, Both our major right wing and left wing parties were in agreement that this is what should happen, there was no political polarisation.
The government formed a plan, the goal was irradication. We went into lockdown, only essential services continued running. Our infected numbers kept going up for 2 weeks, then they started going down. After a couple of months there were no more infected people. We cautiously came out of lockdown, we still required masks, and social gatherings were restricted to small numbers.
Eventually we realised we were safe. We opened internally everything back up, we no longer needed masks, we could even go to concerts and attend sports at stadiums. We still had a covid count, but that was at the border and not in general population. People could fly into NZ but were required to stay isolated at hotels for 2 weeks. So some covid cases ticked along at a steady (not exponential rate) and there was very little risk in society. At times we had some people sneak out of quarantine and go into general population, this caused much panic and lot of effort to see if the disease had gone into the populus. There was once that the disease got out and Auckland went into lockdown again. The disease was stamped out again and Auckland opened back up.
Eventually the Vaccine was developed and NZ got their hands on it, around a similar time the Omicron variant came, and got into Auckland. Auckland were again on lockdown, but didn't seem to be able to stamp it out. Meanwhile the country was quickly getting vaccinated.
Eventually once a very large percentage of the country got vaccinated, we open up even our international borders, so of course then the disease came in and spread to everyone. But because by then we were vaccinated, our hospitalisation and death rates were much lower than they would have been had we been infected prevaccination.
NZ continued reporting on Covid infections way longer than USA did.
But you will find that what NZ differ on in comparrison to countries that either just let the disease run rampant or those that struggled to contain it in the prevaccine era, is that NZ had a very low Covid deathrate per population.
It is not useful at all to compare our overall infection rates, because as with most countries, pretty much everyone caught Covid sooner or later. Many people caught it multiple times over.
