Coronavirus cases have been on the rise in Israel recently despite vaccination of its population and new evidence suggests that Pfizer vaccine may be just 64% effective against the Delta mutation.
Israel is seeing an increase in cases, even among those who have been vaccinated. On May 30, the country reached just 5 new cases of coronavirus and today records around 300 a day, a huge increase.
Israel’s COVID-19 panel of experts said Monday that half of all infections are among vaccinated adults and that it believes the mutation – which originated in India – is responsible for the development.
Pfizer vaccine and Delta mutation: The worrying facts
The data that were published by the Ministry of Health state that vaccine effectiveness in preventing both infection and symptomatic disease drops to 64% as of June 6. The same time, the vaccine is 93% effective in preventing hospitalization and serious illness from the coronavirus, according to Reuters.
The alarming figures see the light of day when Delta mutation raises fears of a new rise in cases in the US as well. According to the Daily Mail, California, the state with the largest population, said on Monday that the mutation is now the dominant one and is responsible for 36% of cases last month.
Nevada, Arkansas and Missouri are also experiencing an increase in infections, mainly from the Delta mutation.
Health officials in the United States have insisted that the Pfizer vaccine is thought to protect against the Delta mutation, but have not commented on the allegations.
“To some extent this is expected since 85% of vaccinated adults in Israel “They are vaccinated,” said Ran Balicer, head of the committee.
“But the levels at which these cases are moving make some people think that they are extending beyond the expected point and suggest that some reduction in vaccine efficacy against mild disease – but not severe disease – is possible».
The Delta mutation – which is more contagious than other known strains of the coronavirus – has spread around the world in recent weeks. Most people have been vaccinated with the Pfizer vaccine and experts are concerned that it may not fight the mutation as effectively.
The vaccine was considered 94% effective against coronavirus before the latest increases in cases. Balicer, however, stressed that it is too early to panic and to draw quick conclusions about the effectiveness of the vaccine.
