The science says everyone needs a COVID-19 booster shot — and soon
Should we be prepared to book our third jab? Available vaccines are working well, but waining efficacy and small percentages of nations refusing vaccinations have opened to door for dangerous variants to cause trouble. Pulitzer Prize-winning journalist Laurie Garrett argues that the biology of the Delta variant has made mass mRNA revaccination an urgent necessity. "The World Health Organization (WHO) has voiced opposition to third dosing in richer nations before making primary doses available to billions of people in middle-income and poorer countries. It’s a completely reasonable point, both morally and strategically, in the war against COVID-19. But evidence now points in an alarming new direction, suggesting that fully vaccinated individuals can carry the delta variant in their noses and mouths, shedding in some cases just as much virus to infect others as do unvaccinated infected individuals."
