It's the virus, stupid.

When the vaccines were first introduced in December 2020, the virus they were designed against was altogether different from what it is today. SARS-CoV-2 had little substantive functional evolution from late 2019 until we saw the Alpha variant in the first months of 2021. It was, in retrospect, an easy target with a fraction of the immune escape and transmissibility that we are dealing with now. Had the virus not subsequently evolved so profoundly, its containment would have been straightforward and we wouldn’t be talking about a pandemic right now in the present tense. Breakthrough and reinfections wouldn’t be commonplace. Population-level (“herd”) immunity would have been possible. The 95% efficacy of the mRNA vaccines against symptomatic infections, hospitalizations and deaths, exhibited waning in latter half of 2021, during the Delta wave, but was fully restored with a 3rd shot. Reinfections were less than 1%. We were prevailing over the virus.
Indeed,
in 2021 more than 20 million deaths were prevented by vaccines as shown below and vaccines are substantially adding to that life-saving capacity in 2022.
But let me emphasize: the culprit in all of this isn’t our vaccines, which are now providing little to no protection against infections and transmission. They are damn leaky, which only arose from the emergence of Omicron and has gotten progressively worse as we moved to BA.5 .
It’s the virus. That’s why we’ve started to see a crack in protection vs. severe disease from vaccines with boosters,
as I previously reviewed (boiling frog metaphor). It’s that we have not gotten ahead of the immune escape properties of virus with a bolstered mucosal immunity strategy—local IgA, neutralizing antibodies in the upper airway—via nasal or oral vaccines to solidify our 2nd layer of defense. Or inhaled interferons to jack up our first line of defense. Or developing a variant-proof vaccine.
As anyone who follows me on twitter knows I have been very critical of the CDC, White House, and FDA for
their management of the pandemic. But to pin the deaths on the current administration, such as below, solely on the basis of poor management, is off-base. It’s primarily that the virus had been morphing to far more challenging versions. Poor management and full reliance on the original vaccine success (“vaccine only strategy”) are certainly contributing factors.
