An Israeli health expert has said that although officials are satisfied with the results reported about the effects of the fourth coronavirus shot, they expected more from the second booster.
“The preliminary results showed a five-fold increase in antibody levels, it’s good news, but it’s not enough, we were hoping for better results,” Director of the Infectious Diseases Unit at Sheba Medical Center Prof. Gili Regev-Yochay told Ynet.
** You cannot fight this Hydra with a single weapon. It requires defence in depth. It requires a multi-layered approach where vaccines represent one single element of a much larger firewall. **
* According to Hesiod, the Hydra was the offspring of Typhon and Echidna. It had poisonous breath and blood so virulent that even its scent was deadly.

Heracles required the assistance of his nephew Iolaus to cut off all of the monster’s heads and burn the neck using a sword and fire (Wikipedia)
