AstraZeneca boss says vaccine effective against variants - (The Sydney Morning Herald via NewsPoints Desk)

  • AstraZeneca's COVID-19 vaccine will offer strong protection against both the Brazilian and South African coronavirus variants, The Sydney Morning Herald reported.

  • CEO Pascal Soriot said new data weakened the result of a South African study which found the vaccine had only 10% efficacy against the local variant.

  • "We have several vaccines that protect well against severe disease for all viruses," Soriot said, adding  "but out of an abundance of caution, we are developing a South African variant vaccine, and people might get a booster in the northern hemisphere autumn if necessary."

  • New unpublished data showed the vaccine was also effective against the Brazilian variant, he said.

  • Soriot noted that all vaccines, including from AstraZeneca and Pfizer, had lower efficacy in young people, because the vaccines were less effective in preventing milder disease.

  • "And so what you see in these studies is 100% protection against severe disease, but there was also no severe disease in the control arm, because they were all young," he said, adding that "in the South African study, I think it's more a reflection of the type of patients than on the vaccine itself."
