A preservative in AstraZeneca s Covid vaccine may trigger a rare overreaction from the immune system that causes blood clots, a scientist has claimed.
Tiny numbers of people given the jab or the one made by Johnson & Johnson have developed a clotting condition that spooked some countries into turning their backs on it.
The reasons for this have been unclear but one German expert has suggested it may begin with a chemical used to make the vaccine.
EDTA, or ethylenediaminetetraacetic acid, might trigger an immune overreaction by forming clumps using platelets in the bloodstream.
EDTA commonly used in medicines and cosmetics may make more ingredients of the intra-muscular jab leak into blood vessels.

Govt hiring 9,675 teachers, medics
THE government yesterday announced 10,675 employment opportunities for primary and secondary school teachers and health workers.
Addressing a press conference here yesterday, the Minister of State in the President’s Office (Regional Administration and Local Governments), Ummy Mwalimu said the ministry has obtained an employment permit from within the President’s Office (Public Service Management and Good Governance).
Of the total, 2,726 job openings are for health attendants in municipal, district hospitals and health centres, she said, noting that fairness in the recruitment process will be observed.
The remaining 6,949 employment slots are for primary and secondary schools’ teachers, she said, cautioning applicants over conmen seeking the paying of bribes to pursue a promise of job placement. Those who come into such situation should inform the minister personally for proper measures to be pursued
The proposed temporary waiver was first suggested by India and South Africa at a World Trade Organization (WTO) meeting in October and is “gathering support from a large number of developing countries”, Reuters reports. The plan’s backers argue that making coronavirus jabs more widely available is a “vital step” in combating the global pandemic, says the news agency.
The US had previously withheld its support, however, alongside the EU, UK, Japan, Switzerland, Brazil and Norway. But now supporters of the waiver are hoping that “US leadership on the issue could help sway other holdouts”, following the change of heart by Joe Biden’s administration, says Al Jazeera.
