"We need a better vaccine, one that provides years of robust protection with fewer booster shots against a variety of SARS-CoV-2 strains."

"...many of the nanobodies we have identified with this method target variants-of-concern, so they have real therapeutic potential."

Convalescent plasma can prevent hospitalizations and save lives, both for COVID-19 and for the next viral pandemic to arrive, researchers say.

A vaccine delivered through the nose is the key to ultimately controlling the COVID-19 pandemic, an expert argues.

"This is significant progress toward a viable HIV vaccine. While we know this will be a many-step process, each step is an advancement toward our goal."

A new ultra-sensitive DNA test that identifies Lyme disease in horses could have applications for dogs and humans, too, researchers report.

Researchers have shown that they can produce antibodies specific for the COVID-19 virus spike protein from eggs by immunizing hens.

In a new clinical trial, monoclonal antibodies didn't shorten recovery time for COVID-19 patients in the hospital, but they did reduce deaths.

Carefully designed cocktails of antibodies could help treat HIV while reducing the chance that it evolves to "escape" treatment, researchers say.

"...the virus has continued to get smarter and smarter. Even with vaccines, it continues to find new ways to mutate and evade existing antibodies."
