Delta “breaks” vaccinators … CDC announces “change of war”

“Fulant received both doses of the vaccine, but contracted crown.” This new obsession has spread among people like the virus itself and causes anxiety and tension and sometimes questions about the vaccine itself and its viability.

This morning, the Washington Post published leaks from a confidential report from the Centers for Disease Control (CDC) that expressed concern about the rise in so-called “advanced infections,” that is, infections with Crown virus in people who completed the two doses of the drug, the vaccine. So what are these injuries? What worries the latest report? What implications does all this have on the issue of vaccines?

What are advanced COVID infections?

In short, they are infections that “penetrate” the vaccinated person. Because a person is considered to be fully vaccinated two weeks after completing the second dose of vaccine, any infection that occurs later is considered a “penetrating infection” as defined by the CDC.

In addition, according to the CDC, these infections are not uncommon and do not diminish the importance of the vaccine, but are expected due to lack of access to a 100% effective vaccine.

So far, there does not appear to be one age group more susceptible than others to penetrating lesions, as young and old are exposed to these lesions despite receiving the vaccine. However, the symptoms of these injuries vary with age, as the elderly group is more vulnerable than others to more severe symptoms.

CDC Report:

On July 30, 2021, the American newspaper “Washington Post” published a leaked report from CDC, which was presented within the center in order to plan strategies and recommendations for the next phase. The report includes the latest information on infection rates, vaccine efficacy and preventive measures at the next stage.

The difference in the type of infections between vaccines (one or two doses of mRNA vaccines, ie “Pfizer” or “Modern”) and unvaccinated (information according to data between 12-2020 and 4 -2021):

The viral load (the number of copies of the virus) after infection is 40% lower among vaccinated people if they have contracted the virus compared to people who are not vaccinated.

– Vaccines are less susceptible to hyperthermia-related symptoms compared to non-vaccinators infected with the virus, and the average duration of symptoms is shorter for vaccinated people infected with the virus.

Duration of immunity after receiving the vaccine:

To date, the duration of immunity conferred by the vaccine is still unknown, but there are some studies that show high levels of immunity after 20 weeks of the second dose.

How has the effectiveness of the vaccine (VE) changed since its production to date?

Although preliminary figures on the efficacy of mRNA vaccines based on the results of clinical trials and preliminary results in countries after the start of vaccination are high, the current figures are lower than before.

Based on the report leaked to the CDC and based on residency data, the approximate figure for the effectiveness of mRNA vaccines is as follows:

Efficacy in protection against any injury (including injuries without any asymptomatic symptoms): 61%.

Efficacy in protection against infections with moderate symptoms: 75%.

Effectiveness in protection against infections with severe symptoms: 80%.

What about the “delta” mutant?

The “delta” variant has a large portion of the CDC report because it may be responsible for many of these changes in vaccine efficacy. According to the data in this report, there are studies indicating that the risk of contracting the “delta” mutant is generally higher than the risk of contracting the alpha (British) mutant. In addition, there are data from Singapore indicating higher hospitalization rates and a higher need for oxygen or admission to intensive care with the delta mutant compared to other strains.

There are also indications from studies in Massachusetts that there are no differences in viral load between vaccinated and unvaccinated people who develop the delta mutant, which could raise concerns about delta avoidance in the system. immune.

It is also worth noting that the report concluded with a summary of the “delta” mutant that is more contagious and more able to “penetrate” vaccinators and that initial indications show that it is more likely to be more dangerous than strains. previous.

CDC Steps:

At the end of the report, a series of recommendations on how the organization should deal with public opinion about these new facts, and these recommendations begin by saying, “We are aware that the war has changed.”

The report emphasizes the importance of focusing on the effectiveness of vaccines in reducing the risk of acute illness and death from the virus, although this drop in percentage is not as complete as we expect. In addition, the report recommends re-imposing masks even on vaccinators, especially indoors. He also presented the possibility of recommending some labor sectors to make vaccination mandatory for all its employees.

What does this mean for vaccines and epidemic control?

In the midst of all this, it is important to remember that the priority has always been to reduce the number of hospitalizations so as not to exceed the capacity of hospitals and the medical sectors. In fact, today, hospitalization and mortality rates appear to be very low in countries and regions with high vaccination rates compared to the numbers at the start of the epidemic before any of the vaccines occurred, despite the relative pessimism about the future of all this.

However, Kathleen Nezel, a vaccinologist at the Maryland School of Medicine, points out that the goal is to define the goal, which is to prevent cases of acute disease with Covid, and not prevent the origin of the virus. He also says this can be difficult, but it is necessary, because it is clear so far that Corona will accompany us for a long time.

In conclusion, cases of crown infection among vaccinators should not discourage people from going to receive the vaccine, as the objective view of these cases and their proportions, in addition to the effectiveness of vaccines documented by figures and experiences, while not ideal, it should motivate people to receive the vaccine more than before.
