Israeli Researchers Claim Second Booster ‘Not Good Enough’ For Omicron

Israeli researchers say that a fourth dose of a COVID-19 vaccine shot is “not good enough” to combat the Omicron strain of the virus.

Prof. Gili Regev-Yochay is one of the lead researchers of a first-in-the-world study on the efficacy of a second booster shot, or fourth vaccine shot, to boost immunity amid the Omicron wave of COVID-19. A month after the study, which took place at Israel’s Sheba Medical Center, Regev-Yochay says that the fourth shot falls short.

“The vaccine, which was very effective against the previous strains, is less effective against the Omicron strain,” she said, according to The Times Of Israel.

“We see an increase in antibodies, higher than after the third dose,” she continued. “However, we see many infected with Omicron who received the fourth dose. Granted, a bit less than in the control group, but still a lot of infections.”
