Dramatic Negative Effectiveness for Omicron & Delta sub-variants by the Pfizer & Moderna mRNA technology based gene injections at 90 days & beyond (Hansen et al.); decline much more rapid for Omicron
by Paul Alexander
This Danish study  showed that both Pfizer and Moderna COVID-19 vaccines showed negative efficacy against the Omicron variant within only 90 days of administration and that that decline in efficacy was even faster for Omicron than for the earlier Delta variant. This sharp decline is illustrated in the following graph.
The above graph shows that both of the mRNA COVID-19 vaccines predispose toward increased risk for Omicron infection, as the timeline passes the 90-day point, due to negative efficacy.
