In this paper, a SEIRHD model with travel and vaccination is provided to simulate the transmission of Covid-19 between two places and the vac- cination and hospital cost. In the simulation, different policies on travel, contacts, and vaccination have been tested. The results show that for a high vaccinated society, travel restriction is necessary for keeping low contact. When number of contacts has been limited, the impact is immediate and significant. Both reduction in hospitalization and delay in time reaching the peak of hospitalization can be seen. The cost of vaccinating more people is minimal compared with the cost of hospital bill it reduces, which indicates that increasing vaccination rate is desired.
