- The Centers for Disease Control and Prevention released a report Wednesday that admitted that most Americans who get their bivalent booster vaccine are not protected against falling sick with Covid.
- The report found the updated shots were only 48 percent effective at stopping symptomatic infection caused by the XBB.1.5 subvariant for up to three months.
- Those findings mean the bivalent shots – for which the US Government paid $5 billion last autumn – fall short of the World Health Organization’s 50 percent efficacy threshold for an effective vaccine.
