If you would of made this comment in the 70's or 80's you would have been called a commie bastard. You manage in just two sentences to conflate 3 different notions into one single "bad thing ™": science, capitalism and democracy.
Democracy does not equal/result in/require/corelate with/mean the same as/etc. capitalism. Before Marx, the very vast majority of non-democratic regimes have been capitalist.
There is no such thing as "the science" to people engaged in doing science. "The science" is only a concept for people who stay away from scientific pursuit. There is a thing called scientific consensus that means the collection of knowledge scientists widely agree best describes reality at a given moment in time.
The scientific consensus is not controlled by commercial interests for many reasons. Among those reasons here are just two: plenty of science is publicly funded and the scientific consensus is global therefore being beyond the capabilities of any single entity to direct. Individual scientists may be biased, but that bias is not coherent in the population of scientists.
In the case of Covid vaccines, even if "the science" was controlled by commercial interests, that would still not result in a conspiracy. There are 20+ vaccines and each manufacturers commercial interest would be to discredit competitors and sell more of their own.
The scientific consensus is pro-vaccine because vaccines have been prooven repeatedly in the past 100+ years to result in higher quality and longer duration of life. There is no consensus on which vaccine is better (for various definitions of better). But there is consensus that covid vaccines are the best tools humanity has for the foreseeable future to fight against the pandemic. And there is consensus that they are orders of magnitude safer than the disease.
Also, there is no blind single mindedness. The very reason you know about all of the side effects that have surfaced so far is because science was done. If "the science" was controlled, the featured article would not exist. We have known about the existence of side effects of vaccines since the start. Side effects were predicted and expected since before the vaccines existed, because all medication has side effects. They have been measured, and continue to be measured. This study is just one step on our quest to ever more precisely measure those side effects. So, yes, the impact of the side effects has been sufficiently determined to conclude that at the very least vaccination against covid is orders of magnitude safer than the risk of covid itself.
The the confusion you display by corelating such different notions in your comment, shows you have bought a narrative peddled by some grifters, hook, line and sinker. The same as all the people deceived to believe that the MMR vaccine causes autism.
Be sincere with yourself and admit that, at this point in time, the only studies you will consider unbiased are those that will confirm your own bias, namely that you consider the side effects of covid vaccines to be too risky.
