"As a rule of thumb, a total fertility rate of 2.1 births per woman approximates the replacement threshold in affluent countries with high life expectancy—but the replacement level is somewhat higher in countries with lower life expectancy or marked imbalances in the ratio of baby boys to baby girls."
Consider where we are right now in the fight against Covid-19. A few months ago it seemed likely that the development of effective vaccines would soon bring the pandemic to an end. Instead, it goes on, with hospitalizations closing in on their peak from last winter. This is partly due to the emergence of the highly contagious Delta variant, but it also crucially reflects the refusal of many Americans to take the vaccines.
And much of this refusal is political. True, many people who are refusing to get vaccinated aren’t Trumpists, but there’s a strong negative correlation between Donald Trump’s share of a county’s vote and vaccinations. As of July, 86 percent of self-identified Democrats said they had had a vaccine shot, but only 54 percent of Republicans did.
But vaccine refusers aren’t just rejecting lifesaving vaccines, they’re also turning to life-threatening alternatives. We’re seeing a surge in sales of — and poisoning by — ivermectin, which is usually used to deworm livestock but has recently been touted on social media and Fox News as a Covid cure.
The 3 Simple Rules That Underscore the Danger of Delta:
1. The vaccines are still beating the variants.
2. The variants are pummeling unvaccinated people.
3. The longer Principle No. 2 continues, the less likely No. 1 will hold.
