Has Israel found that the COVID-19 vaccine continues to work against the delta variant in preventing serious illness and hospitalizations?

Stevie Rosignol-Cortez, Gigafact

yes

Israel’s health ministry has noted that as the delta variant has become widespread, COVID-19 vaccines have shown a "marked decline in effectiveness" in preventing infections and symptomatic illness, down to 64%. But in a July 5 statement the ministry said the vaccines remain 93% effective at protecting against serious illness and hospitalization.

That view is consistent with the view of authorities at the World Health Organization, in the U.K. and in the U.S. In the U.S. the Centers for Disease Control says research looks reassuring, but it will continue to monitor the vaccines' efficacy.

All experts continue to urge eligible individuals to get vaccinated as the best protection against serious consequences or even death from contracting COVID-19.

About fact briefs

Fact briefs are bite-sized, well-sourced explanations that offer clear "yes" or "no" answers to questions, confusions, and unsupported claims circulating online. They rely on publicly available data and documents, often from the original source. Fact briefs are written and published by Gigafact contributor publications.

See all fact briefs

Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
