A new serological study conducted at an Israeli hospital found that 98 percent of hospital workers who received the second dose of the coronavirus vaccine have developed a high level of antibodies to fight off the virus.
Sheba Medical Center in Ramat Gan, outside Tel Aviv, released the results of the study on its website on Monday.
The study of 102 samples, taken a week after Israel began administering the second dose — when the vaccine is expected to reach peak effectiveness — showed most vaccinated people had higher antibody counts than those who have recovered from COVID-19.
The hospital said that a week after receiving the final dose, antibodies jumped to a level six to 20 times higher than after the first shot.
Two employees developed only low levels of antibodies, the tests showed, one of whom was known to have a weakened immune system.
Dr. Gili Regev-Yochay, director of the Infectious Disease Epidemiology Unit at Sheba, said that the initial results indicated the vaccinated people were unlikely to be carriers or infectious — a matter that scientists have hitherto not determined — as antibody levels were high enough to suppress any virus particles.
