The authorities keep saying that there is no link to the vaccine, until very recently (9th April 2021) with the European Medicines Agency (EMA) reporting links between the AstraZeneca COVID-19 vaccine and the blood clots and low platelet counts in many people who have had this vaccine (TGA, 2021). These findings fully justify the concerns that many countries (approximately 25) who have either banned, suspended or restricted the use of the AZ vaccine. Perhaps, based on the new findings and new research, the restrictions should be expanded or even having the AZ vaccine completely banned, to protect everyone from this and other side effects - which are much higher than the other COVID-19 vaccines.
The TGA also notes that while any specific links to gender are not known, but there have been many more adverse clotting events in women than men. This is a concern as there are more female health-care workers (TGA, 2021).
The Australian Technical Advisory Group on Immunisation (ATAGI) has recently (8th April 2021) changed its recommendation for the AZ vaccine to be used in adults under 50 years of age, because of the increasing risks of clotting issues in older adults.
The TGA recommends reporting any side effects from the AZ or other vaccines to your country's adverse events database, so these issues can be monitored and investigated. If you know of anyone who has any side effects from any of the COVID-19 vaccines, make sure they report the issues to their country's adverse events register.
