Covid-19 vaccine ofSLOTXOPfizer-Biotech There has been a decline in efficiency in South Africa. In terms of preventing infected people from falling ill to hospitalization. Ever since the Omikron mutant appeared last month, In a real-world study published Tuesday (Dec. 14),
Between November 15 and December 7, individuals who received two doses of Pfizer's vaccine were 70 percent less likely to avoid hospitalization from the novel coronavirus, down from 93% during the outbreak. past of the delta mutant
In terms of avoiding infection altogether A study by Discovery Health, South Africa's largest private health insurance company, found that Pfizer's vaccine was effective in preventing contracting COVID-19. It has plummeted from 80% previously to just 33%.
The study is the first real-world analysis of data. On the efficacy of the vaccine against the omikron mutant outside of laboratory studies. While the results of the laboratory studies So far it has been revealed that vaccines have a reduced ability to negate the activity of the virus.
The results of this study are based on an analysis of the Discovery Health's Clinical Research and Insurance Statistics Working Group in collaboration with the South African Medical Research Council (SAMRC).
South Africa was the first nation to alert the world to the Omikron mutant in November. It has raised concerns that it may cause another wave of cases of infection worldwide. and bring about the issuance of travel restrictions to various countries in the southern area of ??Africa
Since then, Africa's daily coronavirus cases jumped to more than 20,000 on Tuesday, with a 35 percent positive test rate. There are still 600 more people who have been hospitalized and 24 have died.
The South African study was based on more than 211,000 COVID-19 tests, of which 78,000 were likely Omikron. Mutants that the World Health Organization lists It is known as a "species of concern" and has been reported in more than 60 countries around the world.
78,000 cases of infected people who are likely to become Omikron mutants. This was based on a domestic comparison of the prevalence of this mutant in previous studies, but also because it was not confirmed as a new mutant. The study therefore cannot provide conclusive evidence of any of the findings.
