There's mounting research to suggest that protecting people who are immuno-compromised from getting COVID is important not just for their sake – it could be critical in the effort to end the pandemic for everyone.

The evidence comes from two separate strands of studies.

Dr. Laura McCoy has been doing the first type. She's an infectious disease researcher at University College London.

"The group of people that I'm particularly interested in are those living with HIV," she says.

She's been studying how well their immune systems respond to vaccines against COVID-19 — specifically the Pfizer vaccine.

So far, it's worked quite well for HIV-positive people.

But there's a catch. In her studies, "all of our participants had really quite well-controlled HIV."

Public health in America is in crisis, a sad fact that the Covid-19 pandemic has made impossible to ignore.

...

As the country’s vaccination campaign slows and doses go unused, it has suddenly become clear that one of the biggest barriers to mass immunity will be persuading skeptical young adults of all backgrounds to get shots. Federal officials expressed alarm in recent days about low vaccination rates among Americans in their late teens and 20s, and have blamed them for the country’s all-but-certain failure to reach President Biden’s goal of giving 70 percent of adults at least an initial dose by July 4.
