How necessary is a fourth vaccination to protect against the coronavirus?
An Israeli study raises new questions.
Tel Aviv - The head of an Israeli study on the effectiveness of a fourth corona vaccination sees an observed five-fold increase in antibodies as "good, but not sufficient".
"We see a certain increase in antibodies, but the increase is not very impressive," said Professor Gili Regev of the Israeli news website "ynet" on Wednesday about the preliminary results of the study.
Shortly after the fourth vaccination, you were back to the same antibody level as shortly after the third, Regev said.
She had hoped for more from a second booster vaccination.
It could not be the goal to get vaccinated against the coronavirus about every four months.
She was glad that endangered population groups such as the immunocompromised and over 60-year-olds in Israel were already being given the fourth dose, said Regev.
“But I'm really not sure if they should be given to everyone now.
We need more information. "
No doubt about the importance of the first booster vaccination
Regev also emphasized the enormous importance of the first booster vaccination: "Those who have received the first and second dose must urgently also receive the third." Those who have not yet received a booster should "run" to the vaccination station, she advised.
Another attempt with a fourth dose of vaccine against the coronavirus began in the Schiba Hospital on Wednesday.
150 participants are to receive a fourth vaccination with Moderna after three doses of the preparation from Biontech / Pfizer.
"A combination of vaccines may be better," Regev said.
It is the first attempt worldwide with a fourth vaccination with combined vaccines.

Only around 61 percent of the 9.4 million Israelis are still considered fully vaccinated.
These are twice vaccinated up to six months after the second vaccination and people with booster vaccination.
30 percent of the population are not vaccinated at all, with nine percent the vaccination has expired.
According to the Ministry of Health, more than four million Israelis have already received the third dose, and more than 70,000 have received the fourth.
