During covid several scientists said the vaccinations will protect better than having been infected.

Considering the vaccines that have been around for years, was that true? Diseases like Measles, Mumps, Chicken Pox, and polio, plus many others, if you get infected you are usually immune for life. I realize there are a small percentage of exceptions. The vaccines for those viruses seem to also protect from catching the illness for life or well into old age.

Regarding Covid, people can get reinfected if they have already been sick, and also they can get sick if they were vaccinated.

I’m just wondering if there is pattern with this sort of thing.

Pertussis immunity from vaccination supposedly wanes in a lot of adults. If you catch pertussis does that immunity wane similarly over time also?

To be clear, I am in favor of vaccination. Risking some of the diseases out there is crazy to me. However, I was one of the jellies who felt if someone had had covid, they should be counted the same as someone vaccinated regarding work or travel unless we had hard data that the vaccine is much more protective.

I wonder if second cases of covid are usually less severe than the first case in an individual.
