According to a medical study by the University of Oregon Health and Science in the United States, experts have reported that two highly active coronavirus strains have been tested on blood samples from people who have been vaccinated or who have lost the code.
Research has shown that the use of Pfizer vaccine against corona type alpha and beta or in the blood samples of about 100 people infected with the disease in the past reduced the rate of antiviral antibodies and beta type. This led to a 9-fold decrease in the level of antibodies compared to the original virus.
The results show that the protection rate against the virus against new strains decreases, especially in people aged 50 and over, which leads to lower levels of antibodies, which is a concern, so vaccination is essential. Efforts to prevent the virus should continue.
The researchers said that the vaccine developed by the American company Pfizer proves to be effective in protecting against new strains of the virus. Still, booster doses of the vaccine will be required in the future, and precautionary measures will have to be taken permanently.
