Pfizer jab 85pc effective after single dose, Israeli data reveals...
The Pfizer vaccine is 85 per cent effective after a single dose, an Isreali study has found as the country's top scientists endorsed the UK approach of giving out the jabs up to 12 weeks apart.
Researchers at Sheba Medical Centre gave one dose to 7,000 healthcare workers in January and found there was an 85 per cent reduction rate in Covid symptoms after 15-28 days, while overall infections - including asymptomatic cases - fell by 75 per cent.
Prof Arnon Afek, the deputy director general at Sheba, said the studies vindicated the UK's approach where there is a significant time delay between the first and second dose, as it shows that the first dose offers strong protection.
"This ground-breaking research supports the British government’s decision to begin inoculating its citizens with a single dose of the vaccine," he said.
Prof Eyal Leshem, Director of Sheba's Institute for Travel & Tropical Medicine added: "This is the first study assessing effectiveness of a single vaccine dose in real life conditions and shows early effectiveness, even before the second dose was administered."
I knew a single jab of the Astra Zeneca one was even more effective after 12 weeks than just 21 days and it now looks as though the Pfizer one is still effective with a longer interval too.
I know some leading scientists such as Professor Macron and the French foreign minister have been highly critical of our approach preferring the go slow or stop alternative, no doubt this will be kept under wraps in France
