Of those 9 cases, six were amongst individuals infected with the South African variant.Some previous studies have actually indicated that the Pfizer/BioNTech shot was less potent versus the B. 1.351 alternative than against other variants of the coronavirus, however still offered a robust defence.While the results of the study might trigger concern, the low occurrence of the South African pressure was encouraging, according to Stern.” Even if the South African version does break through the vaccines defense, it has actually not spread out commonly through the population,” said Stern, adding that the British variant might be “obstructing” the spread of the South African strain.Almost 53% of Israels 9.3 million population has actually received both Pfizer doses.
