Waiting for a vaccine

Two vaccines are close to Brazilians due to the participation of local
research institutes, the Oxford vaccine, where the Brazilian Pedro M. Folegatti is on the development team (author of the article in The Lancet magazine), in which the laboratory also participates Fio Cruz with government incentive, and the Chinese vaccine in which the USP Butantã Institute participates in the testing stage, with an agreement from the São Paulo government for development.
The fact that the British laboratory AstraZeneca, which is in the development of the Oxford vaccine, closed an agreement to produce the vaccine in China through the company Shenzhen Kangtai Biological Products, announced last Thursday, August 6, can cause confusion of interpretation. .
Vaccines also have different developments, while the Chinese vaccine follows the traditional development of vaccines for flu and some common diseases such as measles, cachumba and others, which is the development of a weaker dose of the virus itself thus producing immunity in the body, after some minor annoyances, in the case of the corona virus, a question remains, is there no possibility of reinfection, there are already cases all over the world, which are being studied.
The Oxford vaccine, which has the participation of FioCruz Brazilian Laboratory and encouragement from the Brazilian government, has already been explained in a post that is producing a non-replicating viral vector, it is modified and non-infectious, a protein hidden in the vector takes a protein that produces antibodies and immunizes the vaccinee, the Oxford laboratory says that with two doses it is 100% effective.
There are many other projects under development in the world, Chinese companies participate in addition to these two, in more than 8 of the 26 projects that lead the development of the vaccine because they are already in the stage of testing the vaccines in humans around the globe.
The race for the vaccine has two aspects, the positive is that there is a race that can bring the vaccine earlier, the other fearful is that safety steps are passed, Russia says it has a vaccine soon, but there are doubts about compliance with the protocols before mass vaccination, caution is needed.
