This is not accurate, in fact a lot of the vaccines coming out have been through far more rigorous testing than vaccines in the past due to the massive funding and available test participants.
The Pfizer vaccine has been tested through randomized, double blind, placebo controlled trials of 100,000+ participants. Typically what takes most vaccines take so long to get approved is the difficulty in getting funding and a large amount of test participants. Not to see what effects the vaccine might have over time, in say two years or anything like that.
There is virtually no risk long term for this type of vaccine as biologically the vaccine will take effect within around four weeks of the second dose. It's an impossibility to start getting "adverse" effects from a vaccine two years after receiving it. It's not a seed they inject into your cells or a parasite... The basic biology of how this particular vaccine works is you receive it, you receive the second dose and its effects will typically happen within four weeks, if you were to get adverse effects from it then they will happen in these four weeks.

There are still several areas where they are still awaiting more data. Testing on a wider and more varied populace and the results from that are one part of the data they are waiting on.
Vaccines CAN have different effects based on current health, age, ethnicity, gender etc. If you were to be sceptical this is the point you should be most sceptical about, but again these vaccines have been tested on far more participants than other vaccines in the past as a result of massive funding. So it's not something I would worry about unless you have a rare illness or are extremely extremely unlucky. This is why the EMA & FDA has granted an Emergency Use Authorization rather than outright approval, pending several more months of data.
The Pfizer vaccine has been shown to be extremely effective for prevention of symptomatic disease, which is different than infection. So even after receiving it, while you will be safe from personal harm from the virus they are still not sure in all scenarios whether you can still get the virus after receiving the vaccine or spread the virus it after you take it. So this is another key thing that they are working on finding out through further testing and data. But again, this has nothing to do with possible side effects or anything like that.

I can also understand many people’s questions and hesitation around this vaccine, especially if the scientific and biomedical jargon are difficult to sort through. As someone familiar with this industry, and after reviewing the evidence so far, I am comfortable receiving it.
"Are you concerned that it has been rushed? This should have taken 15 years!" - If one lab had been working on this, scraping by with minimal funding or resources, then yeah - it could have taken 15 years. But when the entire world's brain power and nearly unlimited resources are poured into a problem we can answer questions much more quickly.
The viral genome had already been sequenced, and mRNA produced for initial testing as of last February/March 2020. Clinical trials of well over 100,000 people for something like this is unheard of, and this size gives us greater statistical power and confidence in the findings so far.

I'm not here to force it on anyone, but I would encourage you to look at what the experts who have dedicated their entire careers to this subject are saying about it. I view this as easily one of the most remarkable achievements in human history and it is a shame there are so many misconceptions, and (somewhat frustrating) misinformation flying around about it.
Take care all.
