A policeman was reportedly being treated for blood clots on Wednesday after receiving the Pfizer COVID-19 vaccine on Sunday.
The man, aged 40, had been patrolling the state’s COVID-19 quarantine hotels in the Australian state of Queensland and was rushed to a hospital in the state capital of Brisbane after developing the clots.
 Health authorities were reportedly on high alert and an investigation has been launched. At this stage no formal statement has been made. Deputy Premier, Steven Miles said it was too early to say if the incident was linked to the Pfizer vaccine.
 “What people should be very confident in, though, is that our medical authorities are determined to investigate any of such incidents and provide that information and data, nationally and indeed internationally’’.
 At least 14 people in Australia were known to have had allergic reactions to the Pfizer vaccine, but none had developed blood clots. According to the World Health Organisation, typical side effects of COVID-19 vaccines can include pain at the jab site, fever, fatigue, headache, muscle pain, chills and diarrhoea.
China has administered more than 200 million COVID-19 vaccine doses nationwide; a health official told a news conference on Wednesday.
Meanwhile, the pandemic kept spreading across the world, with the number of new confirmed COVID-19 cases rising for eight weeks in a row, said Mi Feng, spokesperson for the National Health Commission.
There were 5.26 million new cases reported globally earlier, the highest weekly rise since the outbreak of the coronavirus.
As new variants of the virus continue to emerge, China still faces challenges in preventing imported cases and domestic resurgence.
