This important and highly graphic summary gives the evidence from both the US and Israel, which are tracking COVID-19 vaccine failure cases, unlike the US, which is only concerned with reporting COVID-19 in the unvaccinated. What has been shown in the US and Israel, where >80% of strains are the Delta or Delta Plus variants, is that indeed the mutant virus has now eluded the immunity of the vaccines.
To make matters worse, seniors and high-risk patients vaccinated in January 2021 appear to have no protection whatsoever.
Important findings from Israel: The latest data from Israel, which has used the Pfizer mRNA vaccine primarily, indicates that vaccine effectiveness against Delta coronavirus infection and symptomatic (“mild”) disease has dropped from about 95% to about 40%, whereas effectiveness against hospitalization and severe disease (i.e., low blood oxygen levels) remains at 80% to 90% (see chart below).
Importantly, in people who got vaccinated already in January 2021 (primarily the elderly), protection against infection and mild disease may already have dropped to near 0% (see chart above). Moreover, since the Delta covid outbreak is still accelerating in Israel, the effectiveness against hospitalization and severe disease may further decrease (due to lags in hospitalizations).
Meanwhile, from the UK: “In the UK, which has primarily used the AstraZeneca DNA adenovector vaccine, the latest estimate by researchers at the University College London indicates an effectiveness against infection of close to zero percent and an effectiveness against severe disease of about 60%. In very senior citizens, the effectiveness against severe disease may be even lower (due to a weaker immune response).”
Report on long-term analysis: Long-term forecasting of the COVID-19 epidemic
We can expect the same patterns to emerge in the US quickly as of July 17, 2021; the CDC reports the US has 83% of cases with the Delta variant and has not yet sequenced for Delta Plus, which may be even more resistant to the vaccines. The only silver lining in the vaccine implosion is that the Delta strains are far milder and easily treated at home in high-risk seniors. Additionally, those who volunteered for the investigational vaccine program may have milder symptoms.
