Israel says 500K have received 4th vaccine dose
Israel has administered a 4th vaccine dose to more than 500,000 people.
Israel was among the first countries to roll out vaccines a year ago and began widely offering third doses last summer in a bid to contain the delta variant. Nearly half the population has received at least one booster shot.
The country of nearly 9.5 million has reported 8,298 deaths from COVID-19 since the pandemic began.
