The current portfolio is multinational, including investments in Pfizer, Sanofi, AstraZeneca and Johnson & Johnson. Ideally, there should be at least one Chinese vaccine included, but there is not.
Obviously, given the rhetoric of the current administration, using a Chinese vaccine would be politically difficult. You can’t call it “the Chinese virus” and then tell Americans they ought to take a Chinese vaccine. So the Trump administration has made no serious effort to make a vaccine-sharing deal with China.
The matter is hardly settled, but at the very least the Chinese vaccines are not dropping out of contention.
Note that a year’s worth of partial protection still could go a long way. Recommended.
