Mexico City /
According to the publication in the New England Journal of Medicine, The vaccine Janssen, paid by Johnson & Johnson, demonstrates greater efficacy in the use of a single dose. In one study, neutralizing antibodies were detected virus wild-type in 90 percent of the participants on day 29 after the first dose vaccine.
Thus, the effectiveness results with a single dose surpass those that require two. In addition, they point out that the antigen can be stored for three months at temperatures from minus 2 to 8 degrees Celsius and does not require thinning to apply.
It should be noted that the company is working on the development of the vaccine in Mexico and is now preparing to apply for emergency applications in our country.
However, these must be analyzed by organisms such as Federal Commission for the Protection against Sanitary Risks (Cofepris) or the Food and Drug Administration (FDA for the abbreviation in English) in U.S.
