In early March a number of European countries suspended use of the AstraZeneca vaccine over concerns about an increased risk of thrombosisand now the UK Medicines and Healthcare Regulatory Agency (MHRA) has put out a warning about headaches being reported after the vaccine.
Jo Jerrome, chief executive of Thrombosis UK said: “Although serious side effects are very rare, if you experience any of the following from around four days to four weeks after vaccination you should seek medical advice urgently.”
These signs include:
A new, severe headache which is not helped by usual painkillers or is getting worse
A headache which seems worse when lying down or bending over
An unusual headache that may be accompanied by blurred vision, nausea or vomiting.

The MHRA said: “Vaccinated individuals should also seek immediate medical attention if four or more days after vaccination they develop new onset or worsening severe or persistent headaches with blurred vision, which do not respond to simple painkillers.
“The symptoms that should prompt concern are a new onset severe and persistent headache, blurred vision, confusion, seizures, shortness of breath, chest pain, leg swelling, persistent abdominal pain, unusual skin bruising or pinpoint round spots beyond the injection site.
“In reality, for most people that will mean they present to their GP, where they will be triaged by phone or electronic consultation, to see if they need a face-to-face appointment.”

Why side effects occur?
Vaccines work by simulating an immune response to an infectious disease.
This is like a practice run for the body on how to fight the disease, and it also means that various bodily responses are triggered, much like they would if you caught the actual disease.
Dr Jonas Nilsen, co-founder of Practio added: “It is important to bear in mind that we can’t rule out the possibility that a very small number of people might experience adverse effects to the vaccine that we don’t yet know about.”
More than 32 million people in the UK have received at least one dose of a coronavirus vaccine – part of the biggest inoculation programme the country has ever launched.
According to BBC News, the number of first doses administered each day is now averaging around 96,000 -a drop from an average of about 500,000 in mid-March as the schedule of second doses kicks in.
An average of more than 340,000 second doses are now being given a day.
If experiencing any unusual side effects after being vaccinated its crucial you consult with your healthcare professional immediately.
