Although the wave of infection with Omicron is in its infancy, experts are already warning that the ability of the booster (third-dose vaccine; EL) to deal with the virus may be limited.
Researchers at the UK Public Health Trust, UKHSA, have been monitoring tens of thousands of Omicron infections between late November and mid-December.

The findings, which for the time being are only an indication and not a proof, show that the protection provided by the booster against the ability of the variant to cause the appearance of symptoms in the case of infection is significantly eroded after 10 weeks.
"In Pfizer's case, the effectiveness of the vaccine in preventing symptoms after infection dropped to 45% after ten weeks," the researchers wrote in the report. 70% ", they added.
However, the researchers stressed that these findings should be treated with caution because given the limited database and possible bias resulting from those infected being the ones most exposed to the micron, including people who travel and those related to them, and therefore do not necessarily represent the general population.
We also noted that "there are not enough cases of severe micronutrient disease to analyze the effectiveness of the vaccine in terms of its ability to prevent hospitalization."
