“Vaccination reduces the risk of getting to the hospital 25 times.” How high is the viral load of people infected with the Delta variant


The coordinator of the national anti-COVID vaccination campaign, Valeriu Gheorghiţă, states that a person who becomes infected with the Delta strain of the SAR-CoV-2 virus has a viral load that can be 1,000 times higher than the initial version of the virus.

In people vaccinated with Messager RNA-based serum, the antibodies have three times less neutralizing activity than the Delta variant, he says. Gheorghiţă adds, however, that vaccination “reduces the risk of getting to the hospital 25 times”.

Valeriu Gheorghiţă claims that Romania is, at the moment, “well below the European average” in terms of anti-COVID vaccination and once again calls on the population to vaccinate.

“We need to get vaccinated and not postpone this decision because we are looking at what is happening in other countries, at what is happening in Europe, at what is happening in the United States, where the number of cases generated by the Delta variant infection has increased a lot, or from this point of view it is a pity to lose the benefits we have obtained so far “, said Gheorghiţă, on Sunday evening, on Antena 3.

He explained that full-scale vaccination reduces the individual’s risk of developing a serious form of the disease, but also protects others, including in the case of Delta infection.

“Basically, we are talking about a 25-fold reduction in the risk of getting to the hospital if I get sick. By vaccinating myself and those around me, the circulation of the virus will be significantly reduced, the circulation at the population level. (.. .) When we talk about the Delta variant the risk of spreading at the population level is very high and when we talk about the infection of a very large number of people, especially those who are not vaccinated, who do not have any immunity, obviously this it affects, on the one hand, the vaccinated population.

From what point of view? Because the Delta viral variant has several imported characteristics, the most important being related to hypertransmissibility. It is an extremely contagious variant because the viral load of the infected people is estimated to be about a thousand times higher than the infection with the initial variant, with the parental strain. There are, in fact, a lot of mutations that are accumulated in the Spike protein. Basically, the amount of virus that an infected person has in the body is even over a thousand times higher than if he had been infected with the initial variant “, the doctor explained.


According to him, an infected person can in turn generate up to nine other sick people.

He described the situation as “a matter of concern.”

“Practically, studies on serum collected from convalescent people who were infected with that initial variant showed that the neutralizing variant is six times lower than the Delta variant. Also, the antibodies that result from vaccination – for example for vaccines that they use Messenger RNA-based technology – these antibodies have a neutralizing activity three times lower than this Delta variant “, Valeriu Gheorghiţă also stated.

He said the Beta variant, the South African variant, could elude the immune response to the vaccine to the greatest extent.

According to him, vaccination “reduces the risk of getting to the hospital 25 times”, the protection against symptomatic disease being 70, up to 88%.

The doctor specified that there are counties and the city of Bucharest that have a group immunity of over 60%, but “this does not mean that it is enough”.

Gheorghiţă claims that there is an important rate of vaccination coverage in social homes, where the authorities no longer expect outbreaks.

“In the week of July 19-25, there were 660 positive cases of SARS-CoV-2 infection at the national level and 12 deaths were recorded. All deaths occurred in unvaccinated persons, and out of the 660 cases over 82% of “In other words, vaccination reduced the risk of becoming positive five times in the week of July 19-25,” the doctor exemplified.
