Australia further limits use of AstraZeneca vaccine after second death
Australia raised the permissible age to take AstraZeneca's COVID-19 vaccine from 50 to 60 years on Thursday. The restriction follows the death of a 52-year-old man last week from brain blood clots. Health Minister Greg Hunt said the decision was based on new evidence showing a higher risk of the "very rare" condition among people aged 50-59. Australians in this group are encouraged to choose Pfizer, the only other vaccine approved in the country.
