Yup. In the UK when you get vaccinated they (should) give you paperwork that explains how to report any side effects. Obviously if your side effects are severe like you're struggling to breath or something your first action should be to seek medical assistance for the difficulty, not fill out a web form - somebody can do the paperwork later, but there's no reason any person who, for example, experiences otherwise unexplained dizziness for an hour the next day shouldn't write it up themselves if they don't feel they need to trouble a doctor.

The Yellow Card scheme and similar schemes are not useful for direct analysis, they're basically an aggregator for anecdotes. I had a mysterious craving for a kebab after the flu-like side effects from the Oxford vaccine subsided. Probably nothing. I'm not going to waste a doctor's time with a video appointment to report "I suddenly really wanted a kebab". But while musing about it I might as well fill out this web form (with the other boring side effects too), then it goes in the big pile and hey, maybe over the millions of shots given in this country they find 8000 people reported a craving for a kebab which is enough to be interesting even though it's unclear how that could happen or what you should do about it.

Medics are going to write a lot more of these. Patient comes in with unexplained back pain, can't recall any triggering incident, but they did get the Pfizer vaccine 10 days ago? It goes in a Yellow Card report. Again, probably nothing, patients turn up with unexplained back pain all the time, vaccine or not. But collecting these anecdotes gives us a better chance to spot real problems early, so long as we don't mistake them for serious data.
