Another Analysis By Clipping Path Service

Japan's National Institute of Infectious Diseases put the figure at 1.4 times. In addition, another study by Kyoto University also found that the third dose of Pfizer vaccine was only 48.5% effective in preventing infection with BA.5 two weeks after clipping path service inoculation. Experts believe this ratio shows the "limited effect" of supplements. BA.5 has the function of evading immunity, and the vaccine prevention effect of BA.5 is 4 times lower than that of BA.2. 2. South African study: People who have been infected with COVID-19 have an increased rate of secondary diagnoses. 11.5% of the BA.1

cases had a history of previous infection, and 18.9% of the BA.4 and BA.5 cases, which was much higher than the proportion of the previous mutant cases below 3%. 3. Research by Dr. He Dayi from Columbia University: BA.4 and BA.5 immune evasion is 4.2 times that of BA.2 and 19.2 times that of the original strain. 4. A study by Beth Israel Deaconess Medical Center at Harvard University: The study found that after 3 injections of Pfizer mRNA vaccine for 2 weeks, the neutralizing antibody titers of the subjects were BA.4 and BA.5, compared with the original strain of COVID-19. dropped 21 times. 5. Australian study: more and more

patients infected with BA.2 are reinfected 4 weeks after recovery, with an average reinfection interval of 6 to 8 weeks, and almost all reinfected patients are infected by OmicronBA.4 or BA.5 infection. To sum up, many people in the world's population have already been vaccinated or naturally infected, and some have established a certain degree of immune barrier. Therefore, in order to become a mainstream strain, it is necessary to break through the existing immune barrier. Obviously BA.5 has this ability! So let's face the reality that the immunity you get from vaccines and previous
