What about the link to blood clots?
There have been reports in some countries of a small number of people having blood clots after the Oxford/AstraZeneca COVID-19 vaccine.
The MHRA (the UK’s drug regulator) says the current evidence does not suggest the clots were caused by the vaccine and you should still get vaccinated when invited.
A recent US study conducted provided further reassurance.
The study, involving more than 30,000 participants, found no evidence that the vaccine causes blood clots.
You must wait to be contacted.
The NHS will let you know when it’s your turn to have the vaccine.
It’s important not to contact the NHS for a vaccination before then.
