There has not been a long enough period since it has been used in people to determine long term effects.

Given that this study started in 2015… yes, there has. You should make sure to review articles before commenting on them, otherwise you risk inadvertently encouraging the spread of misinformation.

Even Paul Offit said things similar to what other people have been saying in this thread related to serious side effect onset time, but what people didn't realize (or did but ignored for expediency) is that you can't detect rare side effects without giving the vaccine to millions of people in each demographic, not just in total. In the COVID-19 vaccine rollout for example not enough people in the myocarditis high risk zone (males from the onset of puberty to 30, approximately, as well as others at lower but still significant risk) for months got vaccinated for months after the EUA was granted, so they only picked up on the issue for real four months later in April 2021, and did not start putting out warnings in full force until May 2021. This probably could have been picked up by taking troponin readings multiple times in the days after each dose in the trials, but after age and sex stratification, the signal may have been weak. The FDA and CDC have hardly corrected to the extent I think is needed, and the good changes they made were pretty hushed and weak, such as the language around increased dose spacing in myocarditis high risk zone patents. VRBPAC never was able to do a age and sex stratified risk analysis for the first booster either, let alone the second and third. Paul Offit does not recommend you get any boosters unless you are high risk, including just being old (ask: am I eligible for Paxlovid? If not, don't get any boosters.).
