A newer kind of flu vaccine only worked a little bit better in seniors this past winter than traditional shots, the government reported Wednesday.
Overall, flu vaccines barely worked at all in keeping people 65 and older out of the hospital, with roughly 24 percent effectiveness.
The best performance was by a new shot called Flucelvax; it was about 26.5 percent effective in that age group. The difference wasn't as large as some had hoped.
"The big problem is still the same — we need better vaccines. But these incremental improvements are very important," said Brendan Flannery, a flu expert at the Centers for Disease Control and Prevention.
