AstraZeneca and Oxford began work on vaccine against the Omicron variant
The best scientists in the world are in the early stages of creating an “updated vaccine” that works better against the new Omicron variant highly mutant.
Receiving the third dose is relevant to avoid a Covid infection – Oxford-AstraZeneca begins to decline in three months.
Similarly, other research maintains that double-injection vaccinated do not produce enough antibodies to fight against Ómicron due to its mutations, but the total antibody increases when a third injection is given.
Oxford research group leader Sandy Douglas said “preliminary steps are being taken to produce an updated vaccine if necessary.”
He stressed that the same work was carried out for other strains, adding that “adenovirus-based vaccines, such as the one manufactured by Oxford-AstraZeneca, could, in principle, be used to respond to any new variant faster than some had realized.
“They have really important advantages, especially where the needs and logistical challenges are greatest. ”
Yesterday, a study suggested that people who previously tested positive for the variant Delta, but who did not receive the vaccines, “have very little protection against Omicron.”
Doctors measured the antibody response of volunteers who previously I had have tested positive for the Delta strain.
When the highly infectious Omicron variant was introduced into the blood, only one in seven people produced Enough antibodies to attack and neutralize it, meaning having a previous infection alone doesn’t help fight Omicron, Austrian scientists said.
The study of the Medical University of Innsbruck, which did not take into account T and B cell immunity because they are difficult to measure, said that having the Delta strain and undergoing a double vaccine makes people “superimmune.”
Their antibody responses were about four times better than those of people who received double injections, but were not infected.
People who received an injection and then became infected with Covid fared twice as well as those who received Squivated a positive test, the scientists found.
