Bivalent..

 

Americans who got their COVID-19 bivalent booster vaccine are not fully protected against getting sick, according to a new report.

The Centers for Disease Control and Prevention (CDC) released a report that said the updated boosters were just 48% effective at preventing symptomatic infection from the XBB.1.5 subvariant for up to three months.

The World Health Organization (WHO) has a 50% efficacy threshold for an effective vaccine — meaning the bivalent shots fall just below their benchmark.

However, the CDC noted that the main function of the vaccine is to prevent hospitalization and death, rather than transmission and minor illness from the virus  and the booster is still expected to provide protection against severe illness.

Since Covid-19 impacted mainly older people....   Many of these mandates were perhaps not needed for the majority.  Just a thought.
