Five concerning symptoms you should look out for after having AstraZeneca jab

Advice has been given of potentially serious side effects that could be associated with the Oxford / AstraZeneca coronavirus vaccine.

Experts have said that people who have had the sting should be on the lookout for a range of symptoms, which can appear anywhere between four days and four weeks after being vaccinated.

In April 2021, a blood clot with a low platelet count was listed by the European Medicines Agency as a “very rare side effect” of the AZ vaccine and the United Kingdom’s Joint Committee on Vaccination and Immunization (JCVI) stated that it was an “extreme low risk “for people who suffer from blood clots after the AZ sting.

As of April 28, the UK Medicines and Health Products Regulator (MHRA) had received 242 reports of low platelet count blood clots, all in people who received AstraZeneca from around 28.5 million doses administered. Of 241 people who developed very rare blood clots after vaccination, 49 deaths were recorded.

Five signs have been distributed by experts and people are asked to call 111 if they experience the following four days to four weeks after vaccination:

  • severe headache that is not relieved by pain medication or that gets worse;
  • Headache that feels worse when you lie down or bend over;
  • Headache that is unusual for you and that causes blurred vision, feeling or illness, language problems, weakness, sleepiness or seizures;
  • a rash that looks like small bruises or bleeding under the skin;
  • Shortness of breath, chest pain, leg swelling, or persistent stomach pain.

Headache is a common side effect of a vaccine and up to 50% of people can experience headaches after vaccination. Experts said the difference from headache related to the very rare side effect of clotting is that symptoms started four days and up to four weeks after vaccination, were persistent and may be associated with other symptoms like the ones above.

The MHRA and JCVI have both said that the benefits of the AstraZeneca vaccine continue to “outweigh the risks for the vast majority of adults.”
