Brazilian health regulators have revealed that supplies of the Corona virus (COVID-19) vaccine made in Russia, Sputnik V, which are being shipped to its territory contain a live version of the virus that causes the common cold. This was conveyed when the Brazilian authorities explained the reasons for banning imports of Russian vaccines.
As reported by AFP on Thursday (29/4/2021), leading virologist, Angela Rasmusen, told AFP that the Brazilian findings “raise questions about the integrity of the production process” and could lead to safety problems for people with weaker immune systems. if the problem is found widespread.

The Gamaleya Institute in Russia, which developed the Sputnik V vaccine, denied the report.
This problem centers around the ‘adenovirus vector’, a virus that normally triggers mild respiratory disease but in vaccines is genetically modified to prevent replication, and is set to carry DNA instructions for human cells to develop the Corona virus spike protein. This will train the human system to prepare for the real Coronavirus in the future.
The Sputnik V vaccine uses two adenovirus vectors to accomplish this task, namely adenovirus type 26 (Ad26) for the first injection and adenovirus type 5 (Ad5) for the second injection. Berita politik dan ekonomi Rusia
According to documents posted online, scientists at Anvisa – Brazil’s health regulator – say they tested a sample of the booster shot and found that it was ‘capable of replicating’, meaning that once it enters the body, the adenovirus can continue to multiply. self. Politik Rusia
The scientists added that this is likely due to a production problem called ‘recombination’, in which a modified adenovirus has regained the genes needed to replicate while it is growing in human cells engineered in the laboratory. Politik Indonesia
