Israel Vaccine Data Suggests Decrease in Covid-19 Infection Rate After First Dose

Good news! Israel is the world leader with the highest per capita vaccination (I blogged here about it)

"Early data from Israel suggests Covid-19 infection rates began to decrease among a group of vaccine recipients two weeks after they received the first shot of Pfizer Inc. and BioNTech SE ’s vaccine, offering important insights to other countries as they roll out their own campaigns. The small country—whose roughly nine million population ... has vaccinated nearly a fourth of its population in just under a month, the first country to hit that mark as it fights an upsurge in new infections.

Israel’s largest health-care provider, Clalit Health Services, compared test positivity rates among 200,000 people over 60 who received the vaccine with 200,000 that didn’t. Until day 14, there was little difference between the two groups. But after that, the data showed a 33% fall in infection rates among those who had already been vaccinated compared with those who hadn’t."
