Preliminary studies have shown that three doses of Pfizer's covid-19 vaccine neutralize the Ômicron variant. The announcement was made by the companies Pfizer and BioNTech, responsible for the immunizing agent.

The research, carried out with antibody tests, showed that two doses may not be enough to protect people against infection by the new variant. Still, Pfizer and BioNTech believe these two doses can protect against severe cases of covid-19.

The drugmakers said they continue to make progress in developing a vaccine that is specific for Ômicron. The forecast is that the immunizing agent will be available in March of next year, if necessary.
