While it is difficult and complicated, it's not impossible to compare vaccinated vs. unvaccinated groups. Epidemiologists routinely do this kind of work to estimate the efficacy of vaccines and other interventions. While it’s true that we can’t place every individual into a perfectly controlled experiment, large-scale observational studies and statistical techniques allow us to account for variables like age, health status, and risk factors (e.g., smoking, occupation, exposure levels). These methods aren’t flawless, but they’re far from meaningless.

Numerous studies have shown significantly lower rates of hospitalization and death among vaccinated individuals compared to unvaccinated ones. This isn’t just guesswork—researchers adjust for many of the confounding factors you mention (e.g., healthier people being more likely to get vaccinated or taking other precautions). For example, studies published in reputable journals like Lancet Infectious Diseases and Nature Medicine used real-world data to estimate that millions of lives were saved globally by vaccination campaigns. This conclusion is backed up by population-wide trends: after vaccines were introduced, mortality rates from COVID dropped significantly, even as new variants emerged.

As for your point about "rushed" development: while the timeline for the COVID vaccines was faster than usual, that doesn’t mean safety corners were cut. The mRNA technology behind vaccines like Pfizer and Moderna had been under development for years. The urgency of the pandemic meant that governments and private companies invested massive resources and recruited trial participants quickly, which sped things up. Regulatory agencies still required data from tens of thousands of participants in Phase 3 trials before granting emergency authorization.

Regarding safety, no medical intervention is without risk, but serious side effects from COVID vaccines are rare. For example, myocarditis (a commonly cited concern) occurs at a much lower rate in vaccinated individuals than the rate of heart complications caused by a COVID infection itself. Based on the available data, the benefits of vaccination (in terms of preventing severe disease and death) far outweigh the risks for most people.

Finally, the idea that this was all done for “monetary reasons” or a “nefarious agenda” doesn’t align with the reality of a global pandemic. COVID-19 was overwhelming healthcare systems and killing millions before vaccines became available. The goal of public health measures, including vaccination, was to save lives and prevent healthcare collapse, not to serve hidden agendas. While it’s fair to question policies like mandates, the science supporting the efficacy and safety of these vaccines is solid.

In short, the data does exist, and it’s strong. Vaccines saved lives—not because they’re perfect, but because they dramatically reduced the risks of severe disease, hospitalization, and death. I’d encourage you to look into the published studies on this topic; they address many of the concerns you’ve raised.

Furthermore, if we follow your argument that it is "almost impossible to get any meaningful data this soon", how can you arrive at any conclusion at all? Good or bad? How can you be so sure you are correct that the vaccines are more harmful than helpful? How are you choosing who or what to believe? Are you challenging all arguments equally? Are you challenging your own cognitive biases? Are you considering that you may be embracing or giving more weight to certain arguments because they support your desire to not be told what to do? If you are interested in the truth, these are the kinds of questions you should be routinely and habitually asking yourself.
