A study based on Israeli data shows that a fourth COVID vaccine dose improves protection against severe disease for people over 60 by a factor of three.
The study is based on data from earlier this year from over 1 million Israelis who were eligible for the vaccine dose, the Government Press Office says.
The fourth shot gave some protection against infection, but that effect waned over time.
The results were published in the New England Journal of Medicine.
