AstraZeneca vaccine highly effective – Manufacturers

Published

AstraZeneca COVID-19 vaccines distributed to Lagos expires in three months - Commissioner



The British-Swedish pharmaceuticals company AstraZeneca says it has proof that its Covid-19 vaccine is highly effective.

AstraZeneca made the disclosure in a statement on Thursday morning, citing further data from its phase III study with around 32,500 test subjects.

According to AstraZeneca, the vaccine has a 76% efficacy rating against symptomatic Covid-19.

The company added that for people over 65, the efficacy rating is 85%, meaning that among the older subjects in a vaccinated group, 85% fewer cases of illness occurred than among those in a control group.

DPA reports that AstraZeneca spoke of 100% efficacy against severe or critical illness and hospitalization.

One of the figures issued on Thursday is lower than the one issued on Monday, however: On Monday, the company had said that its vaccine was 79% effective against Covid-19.

The drugmaker had promised to provide more data after questions were raised by a US health agency earlier in the week over possibly “outdated” vaccine trial results.

Nigeria is among other African countries that have widely accepted and started inoculation of the vaccine and according to the World Health Organisation, Africa accepted the vaccine 100%.

Mariangela Simao, WHO assistant director-general for drug access, vaccines and pharmaceuticals, told a news conference: “It has all returned to normal, we don’t have any countries refusing the AstraZeneca (vaccine) on the African continent.”
