On Saturday, British drugmaker AstraZeneca said its University of Oxford vaccine tended to provide only modest safety against mild diseases caused by the South African version of COVID-19. This is in accordance with early trial results and data.
According to an article published previously in the day, the research from South Africa’s University of the Witwatersrand and Oxford University showed that the vaccine had substantially decreased efficacy against the South African version.
The so-called British, South African, and Brazilian strains, which tend to spread more rapidly than others, are one of the coronavirus variants currently most important and concerning for scientists and public health experts.
“In this small phase I/II trial, early data has shown limited efficacy against mild disease primarily due to the B.1.351 South African variant,” an AstraZeneca spokesman said in response to the report.
The article we talked about said that not more than 2,000 participants who participated in the trial had been hospitalized or died.

Oxford said on Friday that their vaccine has equal effectiveness against the British strain of coronavirus. It is because of what it does against the strains previously existing.
“However, we have not been able to properly ascertain its effect against severe disease and hospitalization gave that subjects were predominantly young healthy adults,” the AstraZeneca spokesman said.
The company claimed that it assumed that its vaccine could protect against severe diseases, provided that the efficacy of the neutralizing antibody was similar to that of other COVID-19 vaccines that have been shown to protect against serious diseases.
The article said that the research and trial, involving 2,026 individuals among whom half shaped the placebo group, was not peer-reviewed.
Although thousands of individual changes have occurred as the infection spreads through its recent new forms, according to the British Medical Journal, only a tiny minority are expected to be significant or modify the virus in a meaningful fashion.
“Oxford University and AstraZeneca have started adapting the vaccine against this variant and will advance rapidly through clinical development so that it is ready for Autumn delivery should it be needed,” the AstraZeneca spokesman said.
