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.
