Covid, first data from Israel on the fourth dose: it increases antibodies by 5 times

JERUSALEM – One week after the fourth Covid vaccine, the level of antibodies appears fivefold compared to that detected four months after the third dose and this should indicate some efficacy at least against severe symptoms.

These are the very first results of the clinical study conducted at the Sheba Hospital in Tel Hashomer (suburb of Tel Aviv) to test the new injection.
