COVID Vaccine

A COVID-19 vaccine for children younger than 12 is not yet available, but research is well underway and the first shot for some kids in this age group is expected in the fall, doctors say.

Dr. Edward Kenyi, born in South Sudan and now in the U.S., debunks myths about vaccines in his community. Yet he can't convince his mother back home to go for it. Maybe this letter will do the trick.

"You've lost your minds," New Jersey Gov. Phil Murphy yelled at a crowd of demonstrators at a public event. "Because of what you are saying and standing for, people are losing their life."

President Biden has called on states and localities to offer $100 to people who get vaccinated. Many states have already offered cash incentives, with varying results.

On social media late Wednesday, the musician wrote: "I wish to say that I will not perform on any stage where there is a discriminated audience present."

The Serum Institute began mass-producing COVID vaccines even before approval. They've made millions of doses. But so far only about 4% of people in India are fully vaccinated. What went wrong?

The COVID vaccines haven't proved very effective for people living with organ transplants. But getting a third dose of the mRNA vaccines gave a big bump in antibody levels in a new study.

Instead of putting genetic instructions into people whose cells then make a viral protein, the vaccines from Novavax, Medicago and Sanofi carry a spike protein payload.

While natural infection does seem to provide some immunity, studies suggest that it is short term. Vaccination, on the other hand, provides more robust immunity.

From the first vaccine (for smallpox) the questions have been the same. How do we transport it? Who's next to get it? Why so much hesitancy? The answers can be similar — or dramatically different.
