How to keep two vectors of points in One vector

I have a two vectors of CvPoint say 

vector< CvPoint> pa, pb;

pa has 20 points and pb has 30 points;

I want to put both points in one vector, where first colum will have points of pa and second column will have points of pb.

So far, I declared a vector of both points like this: 

vector <vector <CvPoint> , vector < CvPoint> >

I know it is not right. I am not getting how can I keep two vectors in one vector. Looking for guide.

You could use an std::pair to have essentially a 2 column table of vectors; 

std::vector<CvPoint> pa, pb;

...

std::pair<std::vector<CvPoint>, std::vector<CvPoint>> myPair(std::make_pair(pa, pb));

myPair.first == pa /* true */
myPair.second == pb /* true */
