Situation of the Pfizer vaccine in Brazil
The National Sanitary Surveillance Agency (Anvisa) and Pfizer held a meeting on Wednesday (30) to discuss the request for emergency use of the Covid-19 vaccine.
Previously, the US pharmaceutical company had published a note in which it said that it would not enter, at least for now, the request for emergency use in Brazil. The reason would be additional demands by the country: “specific analyzes” that should be included in the documentation. This, according to Pfizer, would slow down the process.
The Pfizer-BioNTech vaccine has been used for several weeks in the United Kingdom, as well as in the European Union, the United States and Switzerland, among other countries.
Several million people have already been vaccinated with the immunizer, with an estimated effectiveness of 95%, but which requires very low storage temperatures, -70 ° C, which makes its distribution difficult.
The following video shows how the Pfizer-BioNTech vaccine works, which uses a technology called messenger RNA, different from the others. The vaccine brings a copy of part of the genetic code of the virus to our body, a kind of recipe for our body to produce a protein from the virus. The presence of this protein triggers the production of antibodies.
