It won't have given you adequate coverage. Covid changes constantly. Even having the current Covid variant doesn't cover you 100 percent against getting the same variant again. And if you become immune, immunity against the current variant only lasts up to 9 months. Meanwhile, you will likely have ended up with some brain damage, perhaps a touch of myocarditis, microvascular problems, blood clots... and you'll probably catch the next variant too.
Get vaccinated.
