Scientific understanding of the coronavirus variant is changing quickly. Here’s a recap of the most important findings.

The trend confirmed warnings that the coronavirus pandemic would undermine progress against other infectious diseases around the world.

But the risk remained rare, and the condition temporary, the team found.

A booster, administered six to eight months after the initial vaccination, increased the level of antibodies against variants first identified in South Africa and Brazil.

The research adds to a growing number of findings suggesting the Pfizer and Moderna shots are protective against the variants identified so far.

Malaria kills about 500,000 people each year, about half of them children in Africa. The new vaccine isn’t perfect, but it will help turn the tide, experts said.

Myocarditis, a rare side effect, occurs mostly after the second dose. So in some countries, officials are trying out single doses for children.
