dpa/GNA – The British-Swedish pharmaceuticals company AstraZeneca has provided new data which it says proves that its Covid-19 vaccine is highly effective.

The vaccine has a 76-per-cent efficacy rating against symptomatic Covid-19, AstraZeneca said in a statement on Thursday morning, citing further data from its phase III study with around 32,500 test subjects.

For people over 65, the efficacy rating is 85 per cent, the company added. This means that among the older subjects in a vaccinated group, 85 per cent fewer cases of illness occurred than among those in a control group.

AstraZeneca spoke of 100-per-cent 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 per cent 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had promised to provide more data after questions were raised by a US health agency earlier in the week over possibly “outdated” vaccine trial results.

On Tuesday, the National Institute of Allergy and Infectious Diseases (NIAID) had said concerns were raised by the Data and Safety Monitoring Board (DSMB) over initial results published by AstraZeneca from its vaccine trials.

AstraZeneca said the new data confirmed vaccine efficacy consistent with the figures announced on Monday, March 22.

The drugmaker also noted that, according to the latest data, the vaccine was well-tolerated, and no safety concerns related to the vaccine were identified.

The British-Swedish company developed the vaccine called AZD1222 together with Oxford University. It has been used extensively in Britain since January.

Germany and several other countries had suspended vaccinations with the AstraZeneca substance for the time being because several cases of cerebral blood clots were reported in relation to vaccination with the substance. The vaccine is being used again.

The Ghana news Agency (GNA) was established on March 5, 1957, i.e. on the eve of Ghana's independence and charged with the "dissemination of truthful unbiased news". It was the first news agency to be established in Sub-Saharan Africa. GNA was part of a comprehensive communication policy that sought to harness the information arm of the state to build a viable, united and cohesive nation-state. GNA has therefore been operating in the unique role of mobilizing the citizens for nation building, economic and social development, national unity and integration.
