We have gone a long way from the original omicron variantpassed through the United States Last winter, creating a record number of infections. According to the centers for disease control and prevention (CDC), the daily cocovies areFall through the country, the new infections reported fell by more than 8% compared to the previous week.

But we are certainly not yet clear. The agency data show that there are still an average of more than 100,000 cases reported each day. On the new cases, 59% are caused by the subvariant Omicron Ba. 2.12.1, and the other infections come from other highly infectious subvariants, such as BA.2, BA.4 and BA.5. While these variants spread throughout the country, one of the best counselors with the country has a new warning for those who are most worried about their protection against the coronavirus. Read the rest to discover what he suggests to those who are "very concerned" by their immunity.

The probability of revolutionary infections could be even higher with two increases in omicron subvariants: BA.4 and BA.5. A study, which has not yet been evaluated by peers but was published on May 26 as pre -printed on the Biorxiv, revealed thatThese two subvallers are about three times more resistant to the immunity of vaccinations. Consequently, the researchers said that they were substantially "more likely to lead to vaccine breakthrough infections".

And this is not the only search indicating a similar concern. A study of June 2 published inScientific immunology noted that even vaccinated individuals who are alreadyhad a revolutionary infection With the original omicron variant could be at risk. According to the study, the revolutionary omicron cases seemed to produce immunity against the BA. 2 sub-variant and the previous variants. But these individuals have not shown improved levels of protection against BA.4 and BA.5.

With this knowledge, it is likely that for a new strategy. During a new interview with WFTX-TV affiliated in Fox in southwest Florida, Covid of the White House TopAnthony Fauci, MD, confirmed that sustainable protectionagainst this virus is difficult to achieve. "Coronavirus, historically, do not give sustainable immunity, and that is why with cold coronaviruses, we can perhaps get a few times a year," he told the media.AE0FCC31AE342FD3A1346EBB1F342FCB

According to Fauci, a new vaccine is probably the next step necessary. "You want a vaccine that if you administer it in a nasal or oral way, it will offer you enough now in the scientific community," he said.

The main manufacturers of vaccines such as Pfizer and Moderna work to update their existing formulas and create new ones since the original omicron variant for the first time last winter. June 8, modernpublished new clinical data On his revised mRNM-1273.214 vaccine, which he describes as a "candidate to booster bivalent containing omicron". According to Moderna CEOStéphane Bancel, the company provides that the revised booster will offer "more sustainable protection against concern" than its original booster, based on its preliminary data.

The company said that it hoped that this new booster will be available for those in the United States at the end of the summer, Bancel calling for the "Senior candidate for an autumn booster 2022". But likeThe New York Times Note, moderndid not free Any data on how its new booster protects against BA.4 or BA.5. According to the newspaper, the modern presidentStephen Hoge said at a presentation of June 8 that researchers always collect data on these subvinations. Hoge has revealed that a very small sample has already suggested that the antibodies created by the shot updated are two to three times lower against the BA.4 and BA.5 subvints compared to the original omicron .

Even if BA.4 and BA.5 are not the dominant variants in the United States at the moment, some vaccine experts have declared that it would be preferable to have a new recall formulation which protects against these latest subvariants due to The speed with which they propagate - not against the original omicron or other subvints which have already been exceeded or which will probably be soon. But according toThe New York Times, Moderna and Pfizer do not have enough time to conduct more clinical trials in people and always deploy new strokes before fall. This could mean that regulators may have to approve updated boosters according to laboratory test data and tests involving animals instead.

When asked if the Americans would accept a recall formulation that has not undergone long human tests, said FauciThe New York Times Whether it's the only option for those who are most worried about the effectiveness of vaccines. "People who are really concerned to protect themselves will do it," he told the newspaper. At the same time, Fauci told WFTX-TV that current coastal vaccines still offered significant protection against hospitalization and death, even if their effectiveness against infection won.
