The Pfizer and Moderna mRNA vaccines have now been in use for 1 year. Scientists now have 1 year of data about any potential adverse long term effects. Most serious adverse effects of previous vaccines occurred in the first 8 weeks. We now have 6 times that length of data.
What's your point? Sanofi Pasteur had 10 years of data investing billions of dollars testing a Dengue vaccine only to mostly try and claw it back later. A year is like a blink of an eye in knowing if a vaccine is safe or not. 10 years is apparently not enough. I'm not an anti-vaxxer. I got my flu shot this year knowing it's mostly ineffective. But has been proven to be safe by decades of use.
The point is pretty straightforward: there is now one full year of data on the safety of the mRNA vaccines and most adverse vaccine events happen in the first 8 weeks.

These vaccines work completely differently from previous vaccines. There is no reason to think there won't be long term adverse effects.
And besides, they have not been widely available for a whole year. Much less than that.

Your link tells only part of the reality - here is the other side - Dengvaxia is approved for use in many countries, including in the EU and the US - the Philippines is the only place it is banned from use. Dengue is a disease that is prevalent in the U.S. territories of American Samoa, Guam, Puerto Rico and the U.S. Virgin Islands. Also this is a live virus vaccine, very different from the mRNA COVID vaccines.
Taking stuff from an unrelated vaccine out of context to imply that COVID vaccines are not safe is very disingenuous. Please use real data from the actual vaccine instead of fearmongering based on unrelated issue. Why is it so important to you to try and discourage the COVID vaccine use?

By what mechanism? There is no reason to think they will.
Antibody dependent enhancement, as seen in Dengue vaccine, is theoretically possible but not likely.
That’s when a previous infection (or vaccine) causes a worse infection when contracting the virus, rather than providing protection. This is an uncommon phenomenon with viruses. Even with the Dengue vaccine it wasn’t common, just common enough to eventually be deemed not safe enough for everyone. (For people who had never been exposed to Dengue the vaccine raised chances of being hospitalized from 1.1% to 1.6%, small but unacceptable).
Here’s an article discussing this potential issue with coronavirus vaccines.
Vaccines: Real-world studies showed high vaccine effectiveness in people up to 60 years old, but not in people over 80. In some cases, serious adverse events or sudden deaths have been reported after covid vaccinations. Their long-term safety and effectiveness remains unknown.
Wrong. There is no reason to believe there WILL be. If there was reason to believe so, they wouldn't have been approved.
And, BTW, they have never really been approved. Pfeizer, for example, is released on an emergency trial basis, for trial to be completed in 2023 and Pfeizer to receive license to produce it. Don't believe me? Will you believe FDA? Then, please, read their emergency vaccine release statement. It's black on white there. Easy find from Pfeizer website. Now, seriously. just READ it, before knee jerk responding. I did.
They currently don't work against the South African variant which has spread across the US and Europe. They're working on a formulation in test. It's not clear whether you need another booster shot.
They've had limited vaccinations in Europe but they've had 37 blood clots before the AstraZeneca vaccine distribution was paused.
