Influenza A virus subtype H3N2

Novel antibody study could lead to near-universal flu protection

A team of scientists took a novel approach to the problem of protecting people against both A and B types of flu viruses. They used llama antibodies to create a nasal spray that would block the viruses before they can take hold in the body, according to a preclinical mouse study published in Science Thursday.

Why it matters: This approach could bring us closer to developing a universal flu vaccine before the next influenza pandemic hits — which, if we're not prepared, would likely kill tens of millions globally. While this study is not on a vaccine per se, it aims to provide similar "near universal" protection against multiple influenza viruses.

The U.S. won't be ready to face a flu pandemic until it improves its vaccines, health care infrastructure, and coordination with other countries — all of which are top priorities for the White House, a National Security Council official said Monday.

Quote"Influenza is a priority to the White House, and represents both a health security and a national security threat... Today, however, we cannot respond with the speed that we need to.""
