The US Food and Drug Administration has delayed granting full approval of Novavax’s Covid-19 vaccine despite it being on track to be cleared until Tuesday afternoon, a person familiar with the situation told CNN.

The U.S. Food and Drug Administration has missed its deadline for making a decision on traditional approval for Novavax's COVID-19 vaccine, a source familiar with the matter told Reuters on Wednesday.

Several previous studies have suggested that shingles vaccinations might reduce dementia risk, but most could not exclude the possibility that people who get vaccinated might have other dementia-protective characteristics, like healthier lifestyles, better diets or more years of education.

TUESDAY, April 2, 2025 (HealthDay News) -- The shingles vaccine can do more than protect seniors from painful, blistering rashes. It also appears to protect older folks from dementia, researchers say.

A new study suggests that getting vaccinated against shingles not only lowers the risk of infection but may also offer some protection against dementia. The new research found that people who got the original shingles vaccine were 20% less likely to develop dementia of any type than those who were not vaccinated.
