Preliminary findings suggest that a fourth dose of COVID-19 vaccine does little to stave off infection from the omicron variant, researchers at an Israeli hospital said.
Sheba Hospital said it gave a fourth dose of either the Pfizer-BioNtech or Moderna vaccine to 274 of its medical workers and found that while the booster increased antibodies, it did not prevent the spread of omicron.
"These are very preliminary results. This is before any publication, but we're giving it out since we understand the urgency of the public to get any information possible about the fourth dose," Dr. Gili Regev-Yochay, director of the hospital's infection prevention and control unit, told reporters at a virtual news conference Monday.
Israel has offered a fourth vaccine dose to people older than 60. The country has been one of the first to vaccinate its population and offer booster shots.
Dr. Nachman Ash, director of Israel's Health Ministry, said the latest information would be considered in deciding whether to widen the booster program to the general population by adding another shot.

In other developments Monday, New Zealand began inoculating children ages 5-11 with Pfizer's pediatric COVID-19 vaccine. More than 120,000 vaccines have been delivered to 500 vaccination centers around the country, the Health Ministry said.
"Getting vaccinated now is a great way to help protect tamariki (children) before they go back to school," Dr. Anthony Jordan, Auckland's COVID-19 vaccination program clinical director, said in a statement.
"The evidence shows that while children may have milder symptoms, some will still get very sick and end up in hospital if they do get COVID-19. Getting vaccinated also helps to prevent them from passing it on to vulnerable family members," he added.
The omicron surge is threatening hospitals in South America.
