JOHANNESBURG – South Africa has suspended plans to vaccinate its healthcare workers with the Oxford-AstraZeneca vaccine after a small clinical study showed that the EU-dominant variant was ineffective in preventing mild to moderate illnesses Country

South Africa received its first 1 million doses of the AstraZeneca vaccine last week and should start administering shocks to healthcare workers in mid-February.The disappointing early results suggest that vaccination with the AstraZeneca vaccine may not make sense

Preliminary data from a small study suggest that the AstraZeneca vaccine provides “minimal protection against mild to moderate illnesses” caused by the variant in South Africa. The variant appears to be more contagious and results in a fatal one Disease resurgence in the country that currently accounts for more than 90% of COVID-19 cases, Health Minister Zweli Mkhize said on Sunday evening

“The AstraZeneca vaccine appeared to be effective against the original strain but not the variant,” said Mkhize. “We have decided to temporarily stop the introduction of the vaccine. More work needs to be done”

In the study, which has not yet been peer-reviewed, 2000 people attended, most of whom were young and healthy. The average age of the volunteers was 31 years

“Protection against moderate illness, hospitalization or death could not be assessed in this study because the target group was exposed to such a low risk,” said a statement from the University of Oxford and the University of the Witwatersrand in Johannesburg

Scientists will investigate whether or not the AstraZeneca vaccine will be effective in preventing serious illness and death against the variant, Mkhize

said

Other vaccines have shown reduced effectiveness against the variant, but offer good protection against serious illness and death

Public health officials are concerned about the South African variant because it contains a mutation of the virus’ s signature spike protein that existing vaccines target, South African officials say the variant is more contagious and there is evidence that it may be more virulent could

South Africa will urgently introduce other vaccines to vaccinate as many as possible in the coming months, Mkhize said Other South African scientists said Sunday that clinical trials for the Johnson & Johnson vaccine are showing good results against the variant

Initial results for the AstraZeneca vaccine against the variant could have far-reaching implications as many other countries in Africa and beyond have planned to use the AstraZeneca shot.The international COVAX initiative dated the AstraZeneca vaccine in bulk Serum Institute of India bought

Developers of the Oxford AstraZeneca vaccine expect to have a modified sting to deal with the South African variant of coronavirus by the fall, the vaccine’s lead researcher said on Sunday

Sarah Gilbert, lead researcher on the Oxford team, told the BBC on Sunday, “We have a version in the works with the South African spike sequence”

“It is very likely that we will have a new version available in the fall,” she added

Authorities in England went door-to-door last week to conduct COVID-19 tests in eight areas where the South African variant is believed to be spreading after a handful of cases were found in people who had no contact with the country or someone who has traveled there

More than 100 cases of the South African variant have been found in the UK The test flash is an attempt to wipe out the variant before it spreads widely and undermines the UKVaccination rollout

The UK has over 112000 confirmed deaths experienced the deadliest coronavirus outbreak in Europe, but has launched a faster vaccination schedule than the neighboring European Union so far, the UK gave first coronavirus vaccine to about 115 million people
