Russian officials have mentioned that they are offering "unprecedented cooperation" with Operation Warp Speed (OWS), the US multi-agency body set up to accelerate access to effective Covid-19 vaccines and treatments but the "US is not currently open" to the Russian medical advances.

A Senior Russian official while speaking with newsmen stated that the U.S. isn’t open to their offer due to mistrust as he said:

"There is a general sense of mistrust of Russia on the American side and we believe that technologies -- including vaccine, testing, and treatments -- are not being adopted in the US because of that mistrust

Meanwhile, White House Press Secretary, Kayleigh McEnany said yesterday said that President Donald Trump has been briefed on the new Russian vaccine adding that that American vaccines go through "rigorous" Phase 3 testing and high standards.

However, other US officials have told newsmen that the Russian vaccine is considered half-baked in the United States and is yet to attract US interest in a serious way before the rollout.

Recall that Russia announced on Tuesday that it had developed a vaccine against the coronavirus and President Vladimir Putin said his own daughter had received it but tests are yet to be completed which makes some experts be skeptical about the claims.

Russian officials have further revealed Russia is open to sharing information about the vaccine and it would allow US pharmaceutical companies to produce the Russian vaccine on American soil.
