An interesting
article from the New York Times on Covid just now exploding in New Zealand. They mostly avoided it up until now, so basically no immunity through having caught it, but people over age 12 are 95% vaccinated. That's reasonably comparable to the 95 percent of people ages 16 and older in the US who had antibodies mentioned in this article.
I'm particularly struck by the difference in the number of cases in New Zealand compared with the max we saw in my state, Michigan, in the most recent wave. New Zealand's largest day reported, three days ago, was over 32,000 cases. We've got just about twice the population of New Zealand, and our maximum case day had just over 20,000 cases. That's about a three-fold per capita difference. Not sure what's causing such a large difference. I thought maybe kids, but a
breakdown by age group doesn't really support that. I'm not sure what vaccines they took there, or when, or if they're boosting.
