This may indicate – without being a categorical assertion – that this variant can “evade”The immune system of a person.
“To date, there is limited evidence available and not peer-reviewed on the efficacy or effectiveness of the omicron vaccine.”, Indicated the organization in an update of the information gathered on this issue, which is at the center of concerns throughout the world.
The WHO pointed out, on the other hand, that the evidence is more solid regarding the advantage that omicron has of spreading compared to the delta variant, since in countries where local transmission of the former has been detected, it is being observed that cases they double in 1.5 to 3 days.
Ómicron is spreading rapidly in countries with high levels of immunized populations and it is still unclear whether this is due to it evades immunity, because it spreads more easily or a combination of both factors, based on these data.
“Given current data, omicron is likely to outperform delta in community transmission scenarios”, Indicated the WHO.
Omicron has so far been detected in 89 countries, and the threat it will pose will become clear when scientists can confidently answer a number of key questions, such as what is its level of transmissibility and how well current vaccines or an infection work. previous covid protection against infection, transmission, serious illness or death
