Omicron produces a 40-fold reduction at the level of neutralization antibodies produced by people who have received two doses of pfizer-bionech SE shot, compared to detected tensions in China almost two years ago.
Researchers in South Africa have found in the initial study that the Pfizer vaccine against Coronavirus (Covid-19) is actually giving less immunity to omicron variants than the other main virus versions. In the laboratory experiments conducted at the African Health Research Institute in Durban, observed that Omicron resulted in a 40-fold reduction at the level of the neutralizing antibodies produced by people who had received two doses of Pfizer-Bontech Se shots, compared to detected strains in China almost two last year.
Alex Sigal, Head of Research in the Laboratory, said that the loss of immune protection is “strong, but incomplete” and that further efficacy studies are needed to take over the exact level of the impact of the vaccine caused by this disease by this new tension.
Speaking at the first reported experimental presentation that measures the efficacy of the Pfizer Covid-19 vaccine against Omicron, Sigal said there would be “more breakthroughs” immune enveloned vaccines when he encouraged the idea to protect themselves against our own new variants.
“Good booster might reduce the possibility of your infection, especially severe infections that lead to a more severe disease,” Bloomberg news agency said as researchers said. “People who don’t have a booster have to get it, and people who have previously been infected must be vaccinated.”
Although this is the initial study of the efficacy of the vaccine that existed against Omicron, the preliminary result has raised concerns that the immune protection of vaccination or the previous battle of Covid-19 may not be enough to stop reinfection or distinguish fresh waves of cases and inpatients.
However, an official who officially said on Tuesday that there was no reason to assume that Omicron was more severe than the variant that came before, or that the existing vaccine would fail against it. Michael Ryan, director of the emergency state of the World Health Organization, told AFP in an interview that currently there is no indication of suggesting the existing vaccine will fail to protrote Omicron to the worst results of the disease.
A similar guarantee was used on Tuesday by US infectious disease experts Anthony Fauci, who said that Omicron was certainly no worse than the previous strain, including Delta.
However, the two experts agreed that more epidemiological data from around the world was needed to affirm the scientific consensus about this. Since South Africa announced the discovery of Omicron on November 25, around 450 researchers globally have worked to isolate the variants of patient specimens, fostering them in the lab, verifying the sequence of its genome, and establishing methods to test them in a blood plasma sample, according to WHO.
Sigal laboratories are the first to isolate the beta variant, the coronavirus tensions identified in South Africa at the end of last year. The latest research in his laboratory involves testing 14 blood plasma samples collected from a dozen people who have been given a second Pfizer-Bionomtech shot about a month before to measure the concentration of antibodies needed to neutralize or block viruses.
