Lead researcher Prof Gili Regev-Yochay said the third dose resulted in “much higher antibodies, neutralization and the antibodies were not just higher in quantity but also in quality” than the second dose – but the fourth vaccine did not show  significant antibody increase.

”Maybe there are a few more antibodies but not much more compared to the third dose,” said Regev-Yochay.
