Moderna researching combination vaccine for COVID booster, flu shot, RSV vaccine
Moderna said it's in the early stages of research for a combination vaccine that would combine three vaccines into one: a COVID-19 booster, a flu vaccine and an RSV vaccine.
There is no current vaccine against respiratory syncytial virus, known as RSV, a virus that causes mild symptoms in most adults but can be deadly for older adults and young children. This new study will only test the vaccine in adults over 60.
The CDC estimates RSV kills 14,000 Americans over 65 each year.
