AstraZeneca denies its COVID-19 vaccine is not very effective for people over 65, after German media reports said officials feared the shot may not be approved in the European Union for use in the elderly.
German daily papers Handelsblatt and Bild said in separate reports the vaccine - co-developed by AstraZeneca and Oxford University - had an efficacy of 8 per cent or less than 10 per cent, respectively, in those over 65 years of age.
German officials were concerned the vaccine may not receive approval from the EU’s medicines authority EMA for use in the age group, Bild said in its online edition.
The reports mark another potential issue for AstraZeneca, which told the EU on Friday it could not meet agreed supply targets up to the end of March after running into vaccine production problems.
