The World Health Organization says it is still not possible to confirm that the vaccine booster neutralizes the microns – 12/08/2021 – Balance and Health

It is still not possible to confirm that three doses of the vaccine against COVID-19 neutral The new omicron variant Corona Virus, the World Health Organization (WHO) said on Wednesday (8). According to the organization, there is an expectation that there will be better evidence of the efficacy of the booster vaccine in the coming weeks as new research is developed.

The announcement comes on the same day that BioNTech and Pfizer say three doses of their product Neuzaram Nova lab test variant. According to the companies, two doses resulted in a significant decrease in neutralizing antibodies against the new strain, but a third dose increased neutralizing antibodies.

Omicron has already been identified in 57 countries, including Brazil, according to new data from the World Health Organization.

The new strain raised the alert status of the international community because of it A large number of mutations.

Of most concern is the 30 found in the S protein, which the virus uses to enter human cells. Current vaccines are produced from these proteins, and therefore there are doubts about it Could be less efficient against this strain.

In addition to Pfizer and BioNTech, other companies are already developing studies targeting a third dose of Omicron’s immunization devices. Moderna, for example, plans to produce a Specific dose of omicron, which may be ready in March 2022.

Sinovac, the Chinese company that produces Coronavac, is another pharmaceutical company that does a Updated version of Omicron vaccine within three months.

Even with these doubts, the World Health Organization has already indicated that available immunizing agents are still critical to stopping transmission of the virus and preventing deaths from Covid-19.

In an interview on Wednesday, all WHO experts asked countries to increase vaccination rates in order to avoid more dangerous scenarios for a pandemic.

Other open points are the transmissibility and severity of the variable. Preliminary evidence points to this It’s more contagious, and Anthony Fauci, a respected American scientist, has already stated that the micron It can even exceed the transmission level in Delta.

However, other evidence indicates that the variant is unable to generate more severe cases of Covid-19, and does not have a significant impact on increasing the disease’s mortality rate.

For now, protective masks must be strengthened Alternate transition barExperts say. In São Paulo, there were plans to make the use of masks more flexible for December 11, but the state government decided to keep Compulsory outdoor equipment.

The World Health Organization has also stressed the importance of avoiding crowding and increasing the number of tests and sequencing in order to have better monitoring of the state of Omicron around the world.
