My opinion about the data is mostly influenced by the kind of data it is and my notion of common sense. Its self reported adverse reactions. A similar kind of data is gathered all the time for problems with services on the internet. The idea is anyone can go to the internet site and report a problem with a web site or service. For example that they had trouble with reddit or whatever. Of course to determine exactly how many people really had a problem this kind of data is unlikely to be accurate. Obviously not everyone who has a problem will go to the particular site and report one. Also sometimes more people may be trying to use the service more than other times. However, even with these limitations this kind of data seems great at indicating when there are no major problems and where there are major problems with the service. When problems hit and need fixing there is a huge spike. When problems are fixed the spike goes back down. We saw a huge spike in VAERs that follows this exact pattern. Now one can take into account that there are more jabs and boosters in 2021 and the partial 2022 than there are vaccines taken in a typical year. However not more than an order of magnitude more since a very sizable proportion of the adult population usually get flu shots. So one might expect if the covid-19 shots were as safe as taking a flu shot that there would be an increase in reports over normal levels, but would not expect more than a ten fold increase. However the spike is way over a ten fold increase and indicates the covid-19 injections are obviously not as safe as the typical vaccination (which by number is mostly the flu shot).
Now whether the number of deaths reported as being due to the covid-19 injections is going down on VAERs seems an important question to me. If they are going down maybe it indicates that for some reason the injections are getting safer. Maybe because those taking boosters tend to be those who did not get an adverse reaction from earlier injections and that they by nature tend not to be adversely affected.
When I first glanced at the graph I thought for a second: "Hey look at that! Maybe the danger has spiked and is in decline!". But alas, a moment later I realized my eyes had been deceived by not taking into account that most of the 2022 data is not in yet.
