The US laboratory Pfizer’s vaccine is generally less effective against Omigran, but protects against 70% of serious illnesses, according to a study released Tuesday in South Africa and found a new variant in November. There are many uncertainties as to the nature of this new form of Govt-19. According to the first observations of scientists, it is highly contagious, but an unusually high number of mutations raise many fears about its ability to resist the vaccine.
Discovery, the country’s leading private medical insurer, has teamed up with scientists from the South African Medical Research Council (SAMRC) to conduct 78,000 PCR trials based on the results from November 15 to December 7.
“The double dose of the Fischer vaccine shows a 70% effectiveness in reducing hospital admissions,” Discovery chairman Ryan Noch told a news conference online. This vaccine was previously 93% effective against acute illness.
In general, “the effectiveness of the vaccine is significantly reduced with a higher number of brief contaminants in vaccinated individuals,” he continued. The study shows a previous dominant variant with an efficiency of 80% against the delta, with a higher number of re-infections, and a 33% efficacy against the risk of contamination.
But Dr. Cheryl Cohen of the National Institute of Infectious Diseases (NICD), who took part in the study last year, said “the severity of the cases is 25% lower than the first wave of the epidemic.”
Glenda Gray, head of the SAMRC General Medical Research Organization, described the results as “very encouraging”, recalling that “the vaccine is designed to protect against hospitalization and death.”
“Despite the less severe cases, the level of pollution in health systems may be high, considering the rapid spread of Omicron,” he said. Noch warned.
South Africa has seen a rapid increase in pollution since the appearance of Omigron, which is responsible for 90% of cases. It is officially the most infected African country with more than 3.1 million cases and more than 90,000 deaths.
A quarter of the 59 million population is fully vaccinated, which is much higher than elsewhere in Africa but far behind the rest of the world.
The country administers the Johnson & Johnson & Pfizer vaccines, of which more than 20 million doses have been vaccinated to date. The government recently announced a third drug that will start in January.
