People with three doses have seen their protection against infection drop considerably following the emergence of the Omicron variant of SARS-CoV-2, also known as the CCP (Chinese Communist Party) virus.

Pfizer and its partner, BioNTech, on March 15 asked U.S. regulators to authorize second boosters …
