LONDON, April 8: British authorities recommended Wednesday that the AstraZeneca COVID-19 vaccine not be given to adults under 30 where possible because of strengthening evidence that the shot may be linked to rare blood clots.

USA, March 25: AstraZeneca insisted Wednesday that its COVID-19 vaccine is strongly effective even after counting additional illnesses in its disputed U.S. study, the latest in an extraordinary public rift with American officials.

JAKARTA, March 21: AstraZeneca said on Sunday its COVID-19 vaccine contains no pork-derived ingredients, countering an assertion in Indonesia, the world’s most populous Muslim nation, that the drug violates Islamic law.

LONDON, March 16: At least a dozen countries including Germany, France, Italy and Spain have now temporarily suspended their use of AstraZeneca’s coronavirus vaccine after reports last week that some people in Denmark and Norway who got a dose developed blood clots, even though there’s no evidence that the shot was responsible.
