Unlikely to cause problem. Giving people multiple vaccines using different vectors is common and tend to help in reaching immunity. Tests are currently under way for dual inoculation of the Oxford and Russian vaccines. A multi-vaccines protocol is unlikely to include any of the RNA based one however. They are just too expensive and too difficult to store. But a combination of the more traditional is likely.
