USA Todayreports that findings have come from WHO team members from 10 different countries who have spent several weeks in Wuhan in search of answers, from visiting a wildlife market linked to the outbreak, plus research facilities and hospitals.

Embarek said at Tuesday’s conference that while he doesn’t believe his team “change(d) dramatically the picture we had beforehand,” they “improved(d) [their] understanding” and “add(ed) details to that picture.”

As nations around the globe continue to strive to distribute vaccines, afaster-spreading COVID strain first found in the U.K.— the B.1.1.7 strain —is now moving rapidlythrough the U.S.,a new study found, and will be the dominant strain “in a matter of weeks.”

However, both Pfizer and Moderna have said thattheir vaccines are effective against the B.1.1.7 strain, and that they can manufacture a booster shot if needed.
