Delta variant, “Pfizer vaccine efficacy only at 64%”

“Bad news coming from Israel this morning.” This was announced on Twitter by Yaniv Erlich, an Israeli-American scientist, associate professor at Columbia University, relaunching new data from the Tel Aviv Ministry of Health on the protection of the anti-Covid vaccine against the Delta variant of the covid.

“The Ministry of Health – Erlich writes – reports that Pfizer’s effectiveness in protecting against the Delta variant drops to 64% from 94% against other strains. This has important implications for herd immunity and the ability of the virus to evolve further “.

Data on the spread of the coronavirus in Israel, one of the countries with the highest number of fully vaccinated people, show that the delta variant, associated with the lifting of restrictions, causes a reduction in the effectiveness of the Pfizer / BioNTech vaccine used for the vaccination campaign Country, writes Fortune.

Between 2 May and 5 June, the vaccine had shown, in the field in Israel, to be 94.3% effective. Since June 6, five days after the government lifted covid restrictions in early July, effectiveness has plummeted to 64 percent. Last Friday, 55% of the new infections were people already vaccinated.

Instead, the protection against serious cases and hospitalization is only attenuated, it is specified. Between 2 May and 5 June, the protection against vaccine hospitalization was 98.2%, against that of 93% recorded from 6 June to 3 July. Yesterday there were 35 serious cases of covid in Israel, up from 21 on 19 July last.

The Israeli government, which has already reintroduced the use of masks in public spaces, is considering adopting other distancing measures and the possibility of recommending a third dose of the vaccine.

57% of Israelis are fully vaccinated, 88% are part of the population over 50.
