It has been six months since the Johnson & Johnson vaccine received emergency use authorization. What does six months of data show about its efficacy, side effects and protection from variants?
The government has ordered 7,700 doses of sotrovimab. But until further evidence shows it’s effective, the guidelines say it should only be given to patients as part of a human clinical trial.

The virus is evolving and new strains are more transmissible. Will the vaccines work against these new variants? How can researchers stay ahead of the virus’s evolution?
The results indicate that the vaccine efficacy in the UK was 89% for individuals who received at least two doses of vaccine. In South Africa, the vaccine efficacy was 60% in people without HIV.
A biologist explains what proteins do in viruses, how they interact with human cells, how the vaccine delivers mRNA into the cell and how antibodies protect us.
