AstraZeneca vaccine latest: Five worrying side effects to spot – urgent warning issued


The most common side effects of the are pain or tenderness at the injection site. Roughly one in four people have had wider effects like fever, headache, nausea and fatigue. However, if you experience any of the following symptoms after the AstraZeneca vaccine, it could indicate a medical emergency and should not be ignored.

Anyone who experiences a headache for more than four days after having the Oxford-AstraZeneca jab should seek medical attention, the UK’s medicines regulator has said.

People should also get help if they have bruising somewhere other than the injection site after a few days, it added.

AstraZeneca vaccine was the second vaccine that was approved by Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK, developed by researchers at the University of Oxford and made with the drug company AstraZeneca.

Headaches were reported in phase one and two when first tested in healthy volunteers back in April 2020.

It stated mild and temporary side effects were evident including headaches and muscle aches which it added were relieved by over-the-counter painkillers.

Further studies failed to mention any other type of headaches reported by the volunteers.

“Safety remains our number one priority. We have continued to assess the benefit-risk balance of COVID-19 vaccines in light of UK infection rates and the latest information from the MHRA on the extremely rare event of blood clots and low platelet counts following vaccination,” said Professor Wei Shen Lim, COVID-19 Chair for JCVI.

He added: “As COVID-19 rates continue to come under control, we are advising that adults aged 18 – 39 years with no underlying health conditions are offered an alternative to the Oxford/AstraZeneca vaccine, if available and if it does not cause delays in having the vaccine.

“The advice is specific to circumstances in the UK at this time and maximises use of the wide portfolio of vaccines available.

“The COVID-19 vaccines have already saved thousands of lives and the benefit for the majority of the population is clear – if you are offered the vaccine, you should take it.”

Women, people under 55 and those who had a Covid infection in the past were all more likely to experience side effects.

Among all vaccinated users of the ZOE symptom app, one in four (25 percent) had one of these whole-body reactions and two-thirds (66 percent) had a local reaction.

For AstraZeneca, roughly half as many people had a whole-body reaction like fever or fatigue as was recorded in clinical trials.
