Covid figures have not only a surprising overvoltage without explanation. A new version of Omicron seizes the United States, pushing infections, hospitalizations and deaths. The Ba. 5 Omicron subvariant recently became the dominant variant of the country, exceeding the previously dominant subvariant BA. 2.12.1 in just two months, according to the CDC. The latest data from the agency indicate that BA.5 is now estimated at 65% of new cases cowled in the United States

"We do not know yetOn clinical severity de Ba.4 and Ba.5 compared to our other Omicron subvariants, but we know that it is more transmissible and more immunized ", CDC directorRochelle WalinskyMD, said at a White House press point on July 12.

According to the High White House AdvisorAnthony Fauci, MD, BA.5 has a "growth advantage" on the previous omicron subvariants which allows it to escape "significantly" from the immunity produced by vaccination and infection. This means that people with an earlier infection - even from the Omicron variant of Ba. 1 or previous subvariants like BA.2 - are always at risk of reinfection of the newly dominant subvariant.

"If you were infected with BA.1, you really don't have a lot of good protection against BA. 4 or 5," said Fauci during the July 12 briefing. "And in other countries, in particular, which have ba.4, 5 antedant ours, the rate of reinfection is clear that this is the case."

During an interview of July 17 on ABCThis week, Response coordinator cocovated at the White HouseAshish Jha, MD, confirmed that the ability of BA.5 to escape immunity allowed people who wereInfected with coco Only three or four months ago to recover it. "We see high levels of reinfection. We see people who are not up to date on their vaccines have a lot of revolutionary infections," warned Jha.

Virus experts always push vaccinations in the middle of the BA. 5 immune-evasive variant. Even with the capacity of the variant to exceed many defenses, vaccines always produce protection against infection for people up to date with their shots, according to JHA. More importantly, he said that vaccines still keep people out of serious illness. But this protection remains strong only for so long - that is why viruse experts warn more vulnerable people to look at during their last time in view.

"If you have your booster, say, last November or December, you don't have as much protection against this virus as you wish," said Jha. "So, one of the key messages that comes out of this moment is that if you are 50 or over and that if you have not obtained luck this year, in 2022, it is absolutely essential that you are released and get -F one now. will offer a very high degree of protection. "

Since March, all the Americans, 50 and over have been eligible for a second booster cocovid. During the White House press briefing, Walensky warned that "many Americans are under-accredited", which includes many of those over 50 who are not up to date on their recall. According to Walensky, around 100 million Americans obtained their first booster, but only 28% of those over 50 received a second dose of recall.

This is particularly worrying because of the fact that CDC data show that among these 50 years and over, people who only obtained one recall had four times the risk of dying of Covid than those who had two shots recall or more. And although some elderly people can try to wait for booster photos specific to omicron to be published this fall, the experts warn against this.

"I recommend, everyone over 50, if you haven't got a shot in the past six months, if in 2022, you haven't gotten, you have to get one now "Said Jha. "You can always get a booster - a specific booster for omicron - this fall and winter. Obtaining a blow now will not prevent you. But that will protect you for the rest of this summer in the fall. I think that It's really very important. "
