Israel announced on Sunday that it will start offering COVID-19 vaccine booster shots for at-risk adults

• Israel will start offering booster shots for adults with compromised immune systems, such as those with organ transplants.
• The country's health authorities are still weighing if the general public need booster shots.
• After a successful vaccine rollout, the country is seeing a fresh spike in COVID-19 cases.

On Sunday, Israel announced it will start offering a $4, reported Reuters, but it is still considering if the rollout should be made public.

After what was touted a quick and successful vaccination drive in the country, Israel has been seeing a wave of new infections, mainly driven by the Delta variant, over the past month. Israel registered $4, according to data from Johns Hopkins University - a far cry from the low double-digits cases recorded in May and early June.

Fifty-seven percent of Israel's population is fully vaccinated with Pfizer vaccines, raising doubts over the vaccine's efficacy against the Delta variant. A study conducted by the Israeli Health Ministry between June 6 and early July showed $4, reported Bloomberg. But the fall in efficacy may also be due to Israel lifting COVID-19 restrictions in June.

Meanwhile, the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC), have said $4 for now. Pfizer and partner BioNTech SE - the companies that produce the vaccine - said they will $4.

"As seen in real world evidence released from the Israel Ministry of Health, vaccine efficacy has declined six months post-vaccination, at the same time that the Delta variant is becoming the dominate variant in the country," the $4, reported CNBC.

In the statement, the companies said they believe "a third dose may be needed within 6 to 12 months after full vaccination."
