The most common side effects of COVID-19 vaccines are pain or tenderness at the injection site. About one in four people have had wider effects such as fever, headache, nausea and fatigue. However, if you experience any of the following symptoms after receiving AstraZeneca vaccine, it may indicate a medical emergency and should not be ignored.
People should also get help if they bruise anywhere other than the injection site after a few days, he added.
The AstraZeneca vaccine was the second vaccine approved by the Medicines and Health Products Regulatory Agency (MHRA) for use in the UK, developed by researchers at the University of Oxford and manufactured with the pharmaceutical company AstraZeneca .
Headaches were reported in phases one and two during the first test in healthy volunteers in April 2020.
He said mild and temporary side effects were evident, including headaches and muscle aches which he said were relieved by over-the-counter pain relievers.
Other studies did not mention other types of headaches reported by volunteers.
He added: “As COVID-19 rates continue to be under control, we are advising adults between the ages of 18 and 39 without underlying health conditions to be offered an alternative to the Oxford / AstraZeneca vaccine, s ‘it is available and if it does not cause delays. to have the vaccine.
“The advice is specific to the circumstances in the UK at the moment and maximizes the use of the large portfolio of vaccines available.
“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.”
Of all users vaccinated with 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, about half of people have had a whole body reaction such as fever or fatigue, as has been recorded in clinical trials.
