After decimating towns like Dannevirke in 1918-19, back it came in 1921.
This time though, in the Pacific Islands.
The Hawke's Bay Herald Tribune reported:
"Beware influenza! None of us will forget the dreaded influenza epidemic of 1918 and the recent cables telling that influenza in its most severe has broken out in Tonga.
''Prevention is better than cure, the utmost care must be taken. At the first sign of the flu go to bed immediately and do not get out for any reason.
One hundred years since we were urged to drink a cough syrup to ward off a deadly flu, we have moved on.
We now have a vaccine.
A year ago, we didn't. Our 2020 outbreak goals and lockdown experiences were different.
In 2021, we know that lockdown levels and the vaccine combine to slow Covid-19.
And experts believe that if 90 per cent (ideally more) of us are fully vaccinated, the new normal of life unimpinged by Covid is more easily achievable.
That's why NZME - the parent company of the Hawke's Bay Today and NZ Herald - started The 90 % Campaign.
It's a collective goal for our team of 5 million and we have the ability to share that message across our multiple media platforms.
The Ministry of Health is aware of 90 % and supportive of encouraging people to get vaccinated.
Those who are anti-vaccination are entitled to their opinion. As we are ours.
Covid-19 evolves, and we need to keep evolving too.
Anti-vaxxers are entitled to their views, and protests. And should they become hoarse with all that shouting, there is always Bonnington's Irish Moss, $8.55 at Pak'nSave.
