Will vaccines change the course of the pandemic? Inside Story
It aims to protect 450 million people across 27 countries.
The bloc’s leaders have hailed the roll-out of the Pfizer-BioNTech vaccine as a moment of unity and hope.
A group of nurses in Rome was the first in Italy to get the jab. The country was one of the first in Europe to go into lockdown.
More than 70,000 people there have died from the virus since February.
But with a new variant spreading quickly, will the initiative be effective?

All 24 were exposed to the sun. Of those 16 were dark enough so that they didn t burn, 5 burned a little and 3 burned a lot.16 + 5 + 3 = 24. So 1/3 had results inconsistent with SPF 30. It s hard to visualize a random sample that burns after 60/30 = 2 minutes in the sun.
I m a blonde with a history of blistering and basal cell carcinoma I wouldn t participate in this study for love or money.

It wasn t entirely clear to me from the way the paper was written, specifically the sentence I cited. It may be that that sentence was actually meant to say something else that didn t sound as though only 16 out of 24 patients exposed themselves to the sun. Of course, it

Ancient DNA and Archaeology Offer New Insights Into Caribbean
Archaeological research and ancient DNA technology can work hand in hand to illuminate past history. This vessel, made between AD 1200-1500 in present-day Dominican Republic, shows a frog figure, associated with the goddess of fertility in Taino culture.

An international team led by Harvard Medical School s David Reich analyzed the genomes of 263 individuals in the largest study of ancient human DNA in the Americas to date. The genetics trace two major migratory waves in the Caribbean by two distinct groups, thousands of years apart, revealing an archipelago settled by highly mobile people, with distant relatives often living on different islands.
About 6,000 years ago, at the start of the Archaic Age, humans first settled in the islands of the Caribbean. Three thousand to four thousand years later, stone tools gave way to clay pottery and the Ceramic Age began. Another two millennia passed before Europeans sailed across the Atlantic and made first contact.
Those who study and those who live in the region have long wondered: Where did these stone tool-using and clay-crafting populations come from? Were they related to each other? How many people lived in the Caribbean when the Spanish first arrived? How much, if any, ancestry can today’s Caribbean populations trace back to these precontact Indigenous groups?
