Dr. Yeadon, former Pfizer Chief Science Officer, Allergy and Respiratory Disease Division, reported that those who have had Covid or similar coronaviruses have immunity to all Covid variants.
Researchers located those who had SARS1 in 2003 and tested them once again with SARS1. Those people were immune, indicating they maintained their immunity from SARS1 for 17 years.
Then they tested those same SARS1 people with SARS2 (Covid). They were immune.
SARS1 and SARS2(Covid) differ in 22% of their genomes, and that was not enough to end immunity.
The variants are only 1% to 2% different from Covid so if you have had Covid, or SARS1 or any number of similar coronaviruses, you are already immune.
The ‘threats’ of variants are to cover vaccination deaths and keep people locked down and obedient.
