Alex Brenson has an article stating the countries who used traditional vaccines with the full virus aren’t having this problem. >The United States and other wealthy countries relied almost exclusively on mRNA jabs. Those shots were largely unavailable in 2021 to poor and middle-income countries. They represent only about one-quarter of the nearly 13 billion doses administered worldwide. >Instead, poorer nations relied mainly on Chinese and Indian vaccines that use older “inactivated virus” technology. Essentially, those shots work by exposing people to Sars-Cov-2 itself - though the virus particles or “virions” have been chemically damaged so they cannot replicate. >Throughout 2021, American public health officials insisted inactivated virus vaccines were far less effective than the Pfizer and Moderna shots. https://alexberenson.substack.com/p/goodbye-covid-part-2-email-title&publication_id=363080&post_id=75688505&isFreemail=false
