A virologist at Oxford University says that although Coronavirus changes very quickly, its variants have a limit, but it is not yet known when this point could be reached. Dr. Emilia Skirmuntt also says it would take a few weeks to better understand if the new Omicron variant causes more severe, or milder forms of the disease, compared to other variants. Dr Skirmuntt spoke to British television station Sky News.
The world is facing the possibility of a second holiday season with a large number of COVID-19 infections, while family and friends are gathering together to celebrate.
Scientists have not yet concluded whether Omicroni causes severe cases of the disease, but know that vaccination can provide strong protection, against severe symptoms and death.
“There is some unscientific evidence that it is associated with milder symptoms compared to other variants, but we really do not have enough data. Some data suggest the opposite, that he is the same as Delta for example. So we can not say anything at the momentSays Dr. Emilia Skirmuntt, a virologist at the University of Oxford.
There is also evidence that some types of vaccines, especially Moderna, have shown greater efficacy against the virus. Which Dr. Emilia Skirmuntt supports, but she adds that many of the vaccines in use offer protection.
“Pfizer is also effective against Omicron, and most of the vaccines we currently have appear to work very well against these variants after booster dosing.“, She adds.
Scientists say Omicron spreads more easily than other variants. It has already become a dominant variant in the US and England.
“This is a type of virus that changes rapidly, but will change even faster, the greater the number of infections. Each infection is an opportunity to give birth to a new variant, which will be even more transmissible than the variants we currently see. But it can not change forever, because it must be similar to the current variants. However, we do not know when this restriction will occur, when the variants will endSays the virology of Oxford University.
Preliminary studies suggest that immunized people need a booster vaccine to prevent Omicron infection, but even without the extra dose, the vaccine appears to offer good protection against severe cases of illness or death./VOA
