Israel offers COVID booster vaccine for ages 12 and above

Israel has begun offering a COVID-19 booster to children as young as 12, and its prime minister says a campaign that began a month ago among seniors has slowed a rise in severe illness caused by the Delta variant. Announcing the decision on Sunday, top Israeli health officials said the effectiveness of the second dose of the Pfizer-BioNTech vaccine waned six months after administration, making a booster necessary.
