Omicron: Two Pfizer Doses Give 70% Protection Against Hospitalisation
According to the first real-world analysis of protection against serious sickness with the novel strain in South Africa, two doses of the BioNTech/Pfizer vaccine provide 70% protection against being admitted to hospital with the Omicron coronavirus variant.
However, the defence provided against Omicron is less than the 93% protection provided against the Delta version, according to a report from Discovery Health, South Africa’s largest private healthcare provider.
The study also found that rates of severe disease were lower in the early stages of the country’s Omicron wave than in earlier surges. The study has not yet been peer-reviewed.
