At the start of the cocovated pandemic, it was greatly believed that if yousurvived an infection From the coronavirus, you were out of the way to get it again. Since then, we have learned that youcan reinfect- Sometimes several times, and in particular with different variants. It has also become clearer than ever than protection against vaccination alone is not a foolproof way to prevent you from becoming cocovid again (and again). While researchers are still working to better understand the reinfection covids, a virus expert has a new warning as to who could be more at risk than expected. Read the rest to find out if you can be vulnerable to the virus now.

While the subvariant Omicron Ba. 2.12.1 has just become the dominant cocovin variant in the United States a few weeks ago, two new versions of the virus are already placed to take over. According to U.S.News & World Report, Subvariants Omicron Ba.4 and Ba.5 aredistribution across the country Now at a quick pace. In early May, CDC data indicated that these two variants were responsible forAbout 1% of infections. But since June 4, the cover of BA.4 and BA.5 has increased by more than 13%.AE0FCC31AE342FD3A1346EBB1F342FCB

"Until this weekend, there was uncertainty as to whether BA.4 and BA.5 would compete with the current dominant variant", "Alexandre Bolze, PHD, a main scientist at Helix, a company that follows the variants of the coronavirus, told the magazine. But now he expects them soon to become the dominant versions of the virus.

Some experts already fear that the rise of these two Omicron subvariants can propel another peak in infections. "It is possible that [BA.4 and BA.5] can lead to a certain level of overvoltage beyond what we see now or at least slow down the return to a lower" "base of" "Tom Inglesby, MD, director of Johns Hopkins Center for Health Security at the Bloomberg School of Public Health, said in a June call with journalists, by U.S.News & World Report.

According to the Belize, the United States should probably expect to see an "increase in cases" with its increase in these two variants, but it does not suspect that there will be a substantial increase in hospitalizations. "It is too early to say if [a wave] will happen, but we saw that Ba.4 and Ba.5 have had a big impact in certain other countries of the world," added Inglesby.

This does not only experience problems for the few who have not yet been struck by COVID. If you were infected with the original omicron variant Ba.1, you could always find yourself sensitive to the sub -variants BA.4 and BA.5. "People infected in December or January in the first omicron wave can be at risk of being reinfected," said Bolze at the US News & World Report.

The World Health Organization (WHO)warned of the possibility Earlier this month, reporting on June 1 that "evolution of evidence suggests that an Omicron BA.1 infection offers a limited protection against symptomatic diseases caused by emerging omicron sub-libers" .

Wesley Long, MD, pathologist at Houston Methodist in Texas, told NBC 5 Chicago that this was due to the fact that the two sub -Variantscontain a genetic mutation This seems to allow the virus "escape preexisting immunity" of previous infection ", especially if you were infected in the Omicron wave". The original omicron variant did not have this mutation, added for a long time.

The genetic mutation also seems to allow the two Omicron subvariants to escape the immunity of vaccination, according to Long. A study pre -printed on May 26 on the Biorxiv server confirmed this evaluation. The researchers of this study revealed that although BA.2.12.1 is only "modestly more resistant"In the antibodies of vaccinated and boosted individuals that the omicron subvariant of Ba. 2, the Ba.4 and Ba strains quickly distributed are 4.2. Vaccinal breakthrough infections," concluded the ' study.

AccordingKatelyn Jetlina, PHD, epidemiologist and founder of your local epidemiologist, indicates that the two subvariants BA.4 and BA.likely to cause more problems For everyone - even those who are vaccinated and stimulated - than all other omicron mutations.

"After our first wave of Ba.1 massive, Ba.2 tried to take the hand to be exceeded by Ba. 2.12.1. Now, Ba.4 and Ba. 5 gain traction very quickly and seem to be easily exceeded the rest , "Jetlina wrote in a newsletter by e-mail of May 31, out of date. "Given recent laboratory studies, however, this is not a surprise. BA.4 / 5 are particularly good for escaping antibodies and reinfecting people previously infected with omicron, as well as boosted individuals."
