Pfizer not as effective with S. African variant – also for not just vaccinated people but people who had got infected before – https://www.timesofisrael.com/pfizer-vaccine-less-effective-against-south-african-variant-israeli-study-finds/

““Our study validates the clinical efficacy of the Pfizer vaccine, but raises concerns regarding its efficacy against specific SARS-CoV-2 circulating variants,” the authors wrote. “Overall, these results call for a close attention of variant spread, and a [possibility] for new vaccines with improved neutralizing potency against SARS-CoV-2 variants.””

“People who recovered from the virus were also less protected against the South African strain than the British variant.

The authors said people who had been infected by the South African variant were probably unlikely to get reinfected by the same variant.”

This is very important to understand in that IF there is a situation to produce more variants we need to avoid it e.g. Brazil.

It is very bad in Brazil. Europe is talking about quarantine but their data is not even close to Brazil issues.

US falling to 4th spot – under 600 deaths! Brazil on top at 1383

MI leads confirmation – CA leads death
