Israel is pressing ahead with its aggressive campaign of offering coronavirus boosters to almost anyone over 12 and says its approach was further vindicated by a US decision to give the shots to older patients or those at higher risk.
Israeli officials credit the booster shot, which has already been delivered to about a third of the population, with helping suppress the country’s latest wave of COVID-19 infections. They say the differing approaches are based on the same realization that the booster is the right way to go, and expect the US and other countries to expand their campaigns in the coming months.
“The decision reinforced our results that the third dose is safe,” said Dr. Nadav Davidovitch, head of the school of public health at Israel’s Ben-Gurion University and chairman of the country’s association of public health physicians. “The main question now is of prioritization.”
The World Health Organization has called for a moratorium on boosters until at least the end of the year so that more people in poor countries can get their first two doses, but Israeli officials say the booster shot is just as important in preventing infections.
“We know for sure that the current system of vaccine nationalism is hurting all of us, and it’s creating variants," The Associated Press quoted Davidovitch as saying. But he added that the problem is “much broader than Israel.”
Israel raced out of the gate early this year to vaccinate most of its adult population after striking a deal with Pfizer to trade medical data in exchange for a steady supply of doses. It has also purchased large quantities of the Moderna and AstraZeneca vaccines.
Most adults had received two doses of the Pfizer vaccine by March, causing infection levels to plummet and allowing the government to lift nearly all coronavirus restrictions.
But in June, the highly infectious delta variant began to spread. After studying the matter, experts concluded that the vaccine remained effective against the virus, but that its efficacy waned roughly five months after the second shot.
In late July, Israel began distributing booster shoots to at-risk citizens, including those over 60. Within weeks, it expanded the campaign to the general population.
More than 3 million of Israel’s 9 million citizens have gotten a third dose of the Pfizer vaccine, according to the Health Ministry.
In a study published last week in the New England Journal of Medicine, Israeli experts said that in people who had been vaccinated five months earlier, the booster increased vaccine efficacy tenfold compared with vaccinated patients who didn't receive it.
That study tracked about 1 million people 60 and older and found that the booster was “very effective at reducing the rate of both confirmed infection and severe illness,” the Health Ministry said.
