Israeli officials warn that the Pfizer vaccine is “significantly less” effective against the Delta variant of the coronavirus, the strain first seen in India, which now accounts for 31 percent of cases in the United States.
“We do not know exactly to what extent the vaccine helps, but it is significantly less,” said Israeli Prime Minister Naftali Bennett.
The shot still prevents people from becoming seriously ill in Israel, where over 60 percent of the population has received a shock. Only 1.6 percent have become critically ill compared to 4 percent in pre-adult cases.
Concerns are also growing about the effectiveness of vaccines against the Beta variant, which was first identified in South Africa.
The United Kingdom will require all travelers from France – including those fully vaccinated – to isolate themselves for 10 days when they return because the Beta variant spreads there, however, mostly in the Indian Ocean territory of Reunion and Mayotte.
