Tesla recalling 54,000 self-driving cars as they can go through red lights.Girl, two, found dead in garden in London after being reported missing.They found that 70% to 80% of T cell responses were maintained against the Omicron spike protein across the study groups.įor 19 patients who were admitted to hospital with Omicron in South Africa – where the variant was first detected – the authors found that these people had T cell responses comparable to those seen in patients who were admitted to hospital in previous waves of the pandemic, when the Beta and Delta variants were dominant. The authors examined the T cell response from 40 people who had received either one or two doses of the Johnson & Johnson vaccine, 15 who had received two doses of the Pfizer/BioNTech jab, and 15 unvaccinated people who had had previous infection.
