Study: The South African strain reduces the amount of antibodies in vaccines 40 times by two doses of Pfizer

According to a study in South Africa, the vaccine giant's vaccine only partially protects against the Omicron variant.

In recovering patients the level of antibodies was higher.

The Omicron variant can partially evade the protection of Pfizer's vaccine, but an impulse dose can increase the protection - said this evening (Wednesday) in a laboratory at the Health Research Institute in South Africa.

The results of a study conducted by the institute show that exposure to the new strain 40 times reduces the amount of corona antibodies in the blood of a person who has been vaccinated with only two doses of Pfizer vaccine.

In a study conducted in a laboratory in South Africa, blood samples were collected from 12 people who were vaccinated with Pfizer's second vaccine.

The aim of the study was to estimate the concentration of antibodies needed in the blood so as not to infect the variant.

It was found that the highest levels of antibodies against variant Omicron were in the group of Corona recoverers, and not in those vaccinated with Pfizer vaccines.

These results are preliminary and further studies need to be conducted on the subject in order to reach a more unequivocal conclusion.

At the same time, the results obtained from the laboratory study, along with the results of studies from various laboratories around the world, will help determine whether existing corona vaccines should be modified in order to obtain optimal protection against the Omicron variant.

The rapid spread of the Omicron variant in South Africa has raised concerns that the protection of vaccines is partial against the virus and that there is a chance of re-infection among recoverers as well as a new wave of morbidity. The World Health Organization has also warned that Omicron could have serious consequences because it spreads more quickly and is contagious than previous strains of the virus. Despite this, so far hospitals are treating patients with the Omicron variant, which leads to optimism that the strain usually causes a mild illness.

Since the Omicron variant was discovered in South Africa on November 25, some 450 researchers from around the world have begun studying the virus. This is done by isolating samples of the contagious strain, growing it in a laboratory and establishing methods for testing it in plasma samples from the blood.

The World Health Organization has defined the omicron variant as a "worrying variant" but nevertheless, added that there is currently no need for new vaccines designed to deal with the omicron variant and the many mutations of this variant.

The head of the lab's research department, Alex Siegel, said the loss of immune protection that the omicron carries is "significant, I will not go full."

She said there would be "another breakthrough" of immunity caused by vaccination, and the booster dose "would probably reduce the chance of getting sick, especially in a way that leads to a serious illness."

She further said that people who have not received a booster should receive the third dose, and people who have been infected in the past should receive a vaccine dose.

USA: Next week we will publish the test results on the Omicron

The countries of the world continue to examine the effects of the new strain and ways of dealing with it.

For example, in the United States, tests are being carried out to determine the degree of protection of vaccines against the South African strain.

Infectious disease specialist in the United States, Anthony Pauchi, said that "variant omicron is probably more contagious" and added that the results of those tests will probably come next week.
