Lessons from Israel: How long can the two doses protect us from coronavirus?

Israel, which has started administering the third dose of Covid-19 vaccine, is now witnessing a surge in Covid-19 cases.

Israel, an early leader in the global Covid-19 vaccination race, is planning a fourth shot to control the shrinking antibody count among its population. Israel started administering the third booster dose in August. Many countries are about to start booster doses, but scientists said they need more evidence to justify the same.

Israel's coronavirus cases have soared in recent weeks. And this is at a time when about three in five Israelis are fully vaccinated. As of September 12, 2021, the proportion of the fully vaccinated population in Israel is higher than in many countries, including China.
