JERUSALEM: Israel’s plan to parlay its COVID-19 vaccination drive into an exit from the pandemic next month hangs in the balance as new variants of the virus have spurred an increase in infections, a senior official said on Wednesday.

Highly infectious foreign variants are currently flooding Israeli hospitals with serious cases and the newly developed vaccines have yet to be proven fully effective against them, Deputy Health Minister Yoav Kisch said.

Israel currently leads the world on per capita vaccinations, having inoculated about 30 percent of its population of 9 million with at least one dose.

“We are in a war with very low intelligence (about the enemy),” Kisch, a former fighter pilot, said. “That means that things are changing as we go. The enemy is using different tactics and different methods that we are not fully aware of.”

Israel began vaccinating high-risk groups on Dec. 19 in what Prime Minister Benjamin Netanyahu predicted would provide them with full protection by the end of this month and enable the economy to begin reopening in February.

But despite expanded eligibility criteria for the Pfizer Inc. vaccines and the imposition of a third national lockdown, infections and deaths are surging.

“We’re in an arms race — except it’s not an arms race, it’s a race between vaccination and mutation,” Netanyahu said on Wednesday at a virtual meeting of the World Economic Forum.

Governments worldwide “should probably expect the companies that are producing the vaccines at this point to modify their vaccines to accommodate the mutations that they don’t cover now,” said Netanyahu, who is up for reelection on March 23.

Israel’s projections of a vaccine-fueled turnaround last week proved false, Kisch said. Now it is hoping to see in the coming two weeks a reduction in morbidity as well as solid research data showing that the vaccines defeat the variants.

“We are optimistic because, as of now, the knowledge regarding this vaccine is (that it is) effective against them,” said Kisch, a lawmaker in Netanyahu’s Likud party.

If that is correct, that means a delay of only two to four weeks in Israel’s planned exit from the pandemic, he said. If not, Israel could be facing a further delay of six to eight months.

“We’ll have to wait for a new development of a vaccine that will give the answer against this mutation,” Kisch said.

Israel’s Interior Ministry announced on Wednesday that the country’s land crossings with Jordan and Egypt would be closed to travelers, in a bid to curb the spread of coronavirus.

The decision follows the shutdown of the country’s international airport, which took effect on Tuesday. 

“To complete the joint efforts to prevent the increase in morbidity, Interior Minister Arye Deri announced that the land crossings will be closed to Israelis and foreigners,” the ministry said in a statement.
