Israeli study suggests extra booster failed to prevent large number of infections

A fourth dose of Pfizer’s coronavirus vaccine has shown waning effectiveness against the Omicron variant, according to a trial in Israel, with one of its lead researchers saying the immunization just isn’t “good enough”.

A study involving 154 medical staff at Sheba Medical Center near Tel Aviv found that a fourth vaccine offered only marginal protection against the Omicron strain compared to previous mutations.

“We see an increase in antibodies, higher than after the third dose. However, we are seeing many infected with Omicron who received the fourth dose,” said Gili Regev-Yochay, one of the trial’s lead researchers, adding that although “the vaccine is excellent against Alpha and Delta [variants]”, for Omicron “That’s not good enough.”

Despite the new findings, Israeli health officials have already moved forward with a fourth dose for the elderly, immunocompromised and medical workers starting earlier this month, with some 500,000 people receiving a second booster in addition to an initial two-dose regimen starting Sunday.

Although the trial is still in its early stages and the hospital has not provided specific numbers, Regev-Yochay said she has made her preliminary findings public because recalls are a matter of “great public interest” according to The Times of Israel. She noted that administering a fourth dose to high-risk residents is “Probably” remains the best approach, but suggested that the recall campaign be limited to an even older age group than the current over-60s guideline.

The World Health Organization and the EU medicines regulator, the European Medicines Agency, have warned against the overuse of recalls, although for different reasons. The WHO has called for a more even distribution of vaccine doses around the world, observing that some countries are moving forward with third and fourth shots before many poor countries receive their first. The EMA, meanwhile, highlighted the potential adverse effects of booster shots last week, warning that repeated vaccinations over a short period could lead to “immune response problems.”

One of the most vaccinated countries in the world, Israel was the first to roll out the fourth doses of the vaccine as it experienced a significant increase in coronavirus infections linked to the Omicron strain. Deaths and hospitalizations have seen only a slight increase in recent months, in line with findings suggesting that the latest ‘variant of concern’ produces milder symptoms than previous mutations. Despite reluctance from global health bodies, Chile, Denmark and Hungary have since followed suit by administering the fourth vaccines, while Austrian authorities have recommended them on a regular basis. “without label” base for nursing staff.
