Covid 19 coronavirus: Mysterious disease that halted vaccine trial

A participant in the trial of a promising Covid-19 vaccine suffered from mysterious neurological symptoms including limb weakness or “sensation change,” new research shows.

Oxford University and its partner AstraZeneca halted the vaccine trial because of last week’s scare.

However, the trial has since resumed and the researchers say the symptoms, which emerged in a participant in the UK, were probably not related to the injection.

“After an independent review, these diseases were considered unlikely to be associated with the vaccine or there was insufficient evidence to say with certainty that the diseases were or were not related to the vaccine,” an information sheet for participants reads posted online by Oxford.

“In each of these cases, after considering the information, the independent reviewers recommended continuing vaccinations.”

Researchers have noticed side effects from the vaccine before, but they have been classified as mild or moderate.

A phase 1/2 study published in July reported that about 60 percent of the 1,000 participants who received the vaccine experienced side effects.

All side effects, including fever, headaches, muscle aches, and injection site reactions, were rated as mild or moderate. All reported side effects also decreased over the course of the study.

Trial delays are not uncommon, but last week’s setback is a blow to global hopes that an injection will be ready in the coming months, as many, including the World Health Organization (WHO), considered that the AstraZeneca injection was the main candidate. Worldwide.

Researchers had hoped to find out if the vaccine worked and was safe by the end of the year, but now it seems increasingly unlikely.
