US Covid19 daily vaccinations don't reveal any significant or predictable statistical correlation with daily US Covid19 deaths/cases


Chart Data for cases, deaths, vaccinations from  "Our World in DataMathieu, E., Ritchie, H., Ortiz-Ospina, E. et al. A global database of COVID-19 vaccinations. Nat Hum Behav (2021) Code for this post here.

The long term data for US Covid-19 daily vaccinations, deaths and cases *is scaled* and plotted below in a seven day rolling average. A table of the R language correlation coefficient (using 'cor' which is scaled 1 to -1) is far below.   The table and visual inspection reveal a fairly strong correlation between daily Covid cases and daily Covid deaths. For 2021 only, US Covid daily vaccinations have a correlation coefficient with both cases and deaths close to '0'. This would indicate no correlative relationship between daily vaccinations with either daily cases or daily deaths.

In the second chart,  three overlay rectangles represent three distinct and separate temporal relationships between daily vaccinations and daily cases/deaths over the course of the pandemic:

  1. The green rectangle graphs daily vaccinations increasing while daily cases/deaths decrease.
  2. The purple rectangle graphs daily vaccinations decreasing while daily cases/deaths continue to decrease.
  3. The blue rectangle graphs daily vaccinations increasing while daily cases/deaths increase.

Recent articles and research on Vaccine Induced Immune Escape

Questions about Global Vaccination

Two charts with regression lines below  the break are from a data download from "Our World in Data".  Code is available on request. The charts are intended to show both daily and 7 day averages of:
  • scaled new vaccinations (red)
  • scaled new deaths (black)
  • new cases since the start of vaccinations per daily and  for seven day average (blue).
By visual inspection, the world is apparently climbing its third ladder of cases/deaths peak since the start of mass vaccinations in late 2020. There is little question for some of us that the onslaught of highly transmissible variants means that cases, deaths, hospitalizations will continue to both accumulate and rise as mass vaccination continues. I have these questions:
  • Are the vaccines actually helping us fight Covid-19?
  • Are the vaccines creating through 'immune escape' continuing cycles of more virulent and/or more transmissible variants?
  • Is global vaccination a strategy that will bring continued death to many?
Far below the charts are recent posts and papers that help examine these questions. Click to enlarge the charts.

03.15.2021 Update: Successful Mass Vaccinations or Mass Deaths?

 "The vast majority of V2 and V3 variants and some more recent V1 variants also have a spike E484K mutation. Whereas in the presence of 501N, 484K has a modest positive impact on ACE2 binding 9, when present with 501Y, these mutations together synergistically increase ACE2-RBD binding affinity ~12.7 fold ... Crucially, E484K and other mutations at S/484 also frequently confer protection from neutralization by both convalescent sera ... , vaccine elicited antibodies ... , and some monoclonal antibodies ... There is therefore increasing evidence that viruses carrying the E484K mutation (with or without 501Y) will be able to more frequently infect both previously infected ... and vaccinated individuals ..." 

"The most important issue here is not whether this particular 'super variant' ever arises, but rather that the convergent mutations that have already arisen in members of the different 501Y lineages implies that these viruses are presently on, and are actively scaling, a broad new peak in the fitness landscape. Whatever SARS-CoV-2 variants eventually summit that peak could be a considerably bigger problem for us than any variants that we currently know in that they might have any combinations of increased transmissibility, altered virulence and/or increased capacity to escape population immunity."

"The emergence and ongoing convergent evolution of the N501Y lineages coincides with a major global shift in the SARS-CoV-2 selective landscape"

Update on thoughts on mask tech and mask use

I don't know how much my general thoughts on mask use for the general public have really changed in the last six months. I suspect the Swedish stance ( on mask use is probably still being followed in many countries like Sweden, Norway, New Zealand. Immediately below there are some links to some earlier articles I wrote on mask use for the general public and farther below that are some new thoughts I have had on the new 'Covid-19 killing' mask tech: 

In line with the results of Danish RCT study (, I doubt whether most current mask or 'face covering' use by the general public is actually slowing the spread of Covid-19 in the United States. But I think if you are going to wear a mask in the general public, you should take advantage of the latest tech in masks. Some have suggested N95 or KN95 lines of mask because they are now more available. Without a doubt approved N95 masks, if you can buy or afford them, can provide high levels of protection if fitted correctly. 

Personally, I find 3M N95 masks are excellent to wear while cleaning your heating system, vacuuming your garage, sweeping the patio. But I think it is improbable that the general public will don the tight fitting N95s as they pull masks in and out of their pockets between storefronts. What is more intriguing to me are the advances in 'germ killing' masks whose design appears to take into consideration the contamination dangers of most 'mask for the general public' usage.  Google "masks that kill Covid-19" for more information. 

CNN has a long article on this here:  An article on designing better masks is here: . These two vendors below are selling masks they claim can kill Covid-19 on contact: 

Here is the big problem I have with my mask use:  Many of those of us with Asthma (reputedly some ~25M or 1 out of every 13 in the US - see simply can't breathe well with masks on. The snot, flem and the moisture start to pile up inside the mask which really invalidates the effectiveness of the mask and quite possibly makes a face mask a dangerous harbor of bacteria and a possible infection source; although about this danger is some debate. 

If you are going to use a face mask, you should at least follow the CDC recommendations here: Depending on your budget, I would recommend having some number of high quality, comfortable masks that work for you so you can get through the week without washing or reusing old or unclean masks.
