• Africa surpasses 100,000 confirmed deaths from COVID-19, although the real death toll is likely to be much higher. Although cases are currently going down, many people are still dying because they do not have access to oxygen and basic care.

Lancet publishes a planned analysis of pooled data among 17,178 participants (8597 of whom received the coronavirus vaccine) across four trials of the AstraZeneca/Oxford vaccine, determining the impact of an extended dosing interval on immunogenicity and efficacy. After a single dose of vaccine, from post-vaccination 22 to day 90, efficacy against symptomatic COVID-19 was 76 percent (protection against both asymptomatic and symptomatic infections was 63.9 percent, based on a subset of UK-only data. A longer interval between doses increased efficacy from 55.1 percent (<six weeks) to 81.3 percent (at 12 weeks or more) among people ages 18-55 years. A second dose is recommended for extend the duration of protection. Source
