It seems like it may be the opposite of what you're saying, though. Vaccinated are just as likely to be infected, but are infected for a shorter time and do tend to get less sick. Natural immunity from a previous infection still reigns supreme, though.

Does it mean that a vaccinated person who caught the virus and developed minor symptoms has a better chance to develop longer lasting immunity than those only being vaccinated and without the dangers of no vaccine?

This study doesn't say anything about that, and I haven't seen any studies that look at that question specifically. I have seen studies that look at people who get vaccinated after having recovered from COVID, and they do tend to have the strongest antibodies. But nothing about antibodies from an infection after being vaccinated. I think that would be interesting to see.

This seems wrong, if there's two models that could be consistent with immunization it's:

- Immunization reduces infection risk and severity of breakthrough

- Immunization reduces infection risk but, once infected, severity risk is the same as an unvaccinated person

Both mean you should get vaccinated but the latter means you should be more risk-on if you are vaccinated. The people downvoting me and arguing with me in this thread don't realize that the latter theory, if true, is actually one which leads to more conservative risk taking.

> Natural immunity from a previous infection still reigns supreme

Except for the part where you had to get sick for the first time, risking death and long-covid.

I also remember talks that the previous infection needs to be a serious one - asymptomatic case will not give strong enough immunity. But I'm not sure if that got confirmed.

Well, a very large number of people got infected before they were even eligible to be vaccinated. So it is what it is.

I have also heard that the severity of infection could determine the strength of immunity, but the studies done since then haven't found that to be the case. It may become more clear on a longer timeframe, but as of now who knows.

> Vaccinated are just as likely to be infected

This is definitely false.
