Fourteen Israelis have been diagnosed with COVID-19 despite having been inoculated with a third COVID-19 vaccine dose, according to Health Ministry data reported by Channel 12 news on Sunday.

According to the network, two of those infected after receiving the booster shot have been hospitalized.

It was not immediately clear whether the 14 contracted the virus before or after receiving the booster. Such sporadic instances would not be enough for medical officials to draw conclusions as to the third dose’s general effectiveness in fighting off the Delta variant of the disease.

Eleven of the 14 cases were over the age of 60, and the remaining three were immunocompromised individuals under 60, the network said. The two that were hospitalized were over 60.

Some 420,000 Israelis have been administered a third booster shot so far, in a drive that began last week.
