Covid vaccines have proven to behighly protective Against the coronavirus novel, but nothing is ever 100% Infragrave - especially with regard to coronavirus, which has evolved and mutated over the past year and one half. Health officials and experts have called severalVariations of concern, including a variant native to India and is potentially more transmissible and more likely to circumvent current vaccines. Now, new research has shown that theVariant of India Can be resistant to one of the three vaccines approved by the United States in particular.

The new study, published on June 3 in the Medical ReviewThe lancetShows that people who have obtained the vaccine against Pfizer produce less antibodies against the variant of India compared to other strains of the virus. ResearchersBlood samples analyzed 250 participants who received a dose or two doses of the Pfizer vaccine. They then compared antibody responses against five different COVID strains, including three variants of concern: the variant of India B.1.617.2, Southern Africa variant B.1.351 and U.K. Variant B.1.1.7. According to their conclusions, the entirely vaccinated persons with two doses of the Pfizer vaccine had lower antibody delays against the variant of India in relation to the original Covid strain, which the current vaccines were intended to fight.

When you look at those who have received a single dose of the Pfizer vaccine, the study revealed that the antibody response was even lower. Compared to 79%, which had sufficient levels of antibody against the original strain, only 32% had an adequate response against the variant of India after a dose.

The results are similar to another recent study, posted on May 27 on the Biorxiv website, which has not yet been examined by peers. According to this study, people who received two doses of the vaccine against Pfizer have seen aThree times the reduction of antibodies Target the variant of India. In a statement, the co-author of May of the study,Olivier Schwartz, PhD, the director of France's pastor institute, said the conclusions show that the variant "acquiredPartial resistance to antibodies.

The first June clinical research companionEmma's wall, PhD, hospital consultant from College London University, said additional efforts should be made forhelp protect more Those who get the anti-pfizer vaccine against the variant of India. "The most important thing is to ensure that vaccine protection remains high enough to keep as many people in the hospital as possible," Wall said in a statement. "Our results suggest that the best way to do so is quickly delivering the second dose and providing boosters with those whose immunity may not be high enough against these new variants."

However, experts notified that these results do not necessarily mean that the Pfizer vaccine will not protect you from the variant of India. More search should be done exactlyHow antibodies are correlated with immunity Against the virus, the antibody levels that alone do not indicate how effective a vaccine can be. In addition, lower antibody levels could still provide some protection.

"These data can not tell usIf the vaccine will be less effective to the prevention of a serious illness, hospitalization and death, "Eleanor RileyProfessor of immunology and infectious diseases at the University of Edinburgh, which has not been involved in the study, told Sky News. "We have to wait for the actual data on these results."
