Corona pandemic: is herd immunity achievable?

Status: 07/06/2021 07:55 a.m.

To contain the pandemic, 85 percent of Germans would have to be vaccinated. The chairman of the World Medical Association, Montgomery, considers this herd immunity to be “temporarily unavailable”. Immunologists see the solution in vaccinating children.

According to the chairman of the World Medical Association, Frank Ulrich Montgomery, herd immunity against the coronavirus is “not achievable in the short term”. According to the new calculation models, the proportion of those vaccinated and recovered would have to be around 85 percent, said Montgomery to the newspapers of the Funke media group.

New carelessness: easing despite the ongoing pandemic?

The Robert Koch Institute (RKI) breaks these numbers down a little more precisely. Given the spreading delta variant of the coronavirus, at least 85 percent of 12 to 59 year olds and 90 percent of seniors aged 60 and over should be fully vaccinated.

“If this vaccination quota is reached in time, a pronounced fourth wave in the coming autumn / winter seems unlikely,” said the RKI analysis on Monday.

What is Herd Immunity?

Herd immunity refers to the indirect effect of a vaccination that occurs when a certain proportion of the population is vaccinated, thereby reducing the transmission of the pathogen in such a way that even unvaccinated people have a lower risk of being infected. This occurs when vaccines not only prevent the occurrence of the disease caused by the pathogen, but also prevent infection with the pathogen or its transmission. However, herd immunity does not set in abruptly above a certain threshold value, but increases in intensity with increasing vaccination rates.

Montgomery: “Must convince vaccine skeptics”

“The results show that under the assumptions made, in particular an increasing dominance of the delta variant, the vaccination campaign should be continued with high intensity,” the RKI paper continues.

The institute is cautiously optimistic that the vaccination goals can actually be achieved. In a current survey of citizens, for example, a willingness to be vaccinated was determined that “make the target vaccination rates identified in the model appear achievable”.

World Medical Association chairman Montgomery formulates it more skeptically: “The ten percent who do not want to be vaccinated to die will achieve their immunity by going through an illness.” That will happen “if we drop all precautionary measures”. The key to success against the virus is as high a vaccination coverage as possible for the population, said Montgomery. For this, the vaccine skeptics would have to be convinced and incentives set so that more people can be vaccinated.

Vaccination of children is important

According to the German Society for Immunology (DGFI), that alone will not be enough. The DGFI assumes that herd immunity against the coronavirus cannot be achieved without vaccinating children and adolescents. With the Delta variant, the situation has worsened, said DGFI Vice President Reinhold Förster. “It is much more contagious. It affects adolescents and children very strongly. As long as this group is not vaccinated at all or only slightly, we will not get herd immunity.”

No vaccine approved for children under 12 years of age

However, the Standing Vaccination Commission (STIKO) has not yet issued a general vaccination recommendation for children aged twelve and over. She recommends vaccinations only for 12 to 17 year olds with certain pre-existing conditions such as obesity. Regardless of this, vaccinations are possible as an individual decision by parents, their children and the doctors. There is currently no approved vaccine for children under the age of 12.

According to official information, 56.5 percent of people in Germany have recently received a first dose of vaccine, 38.9 percent are fully vaccinated.

You can

please stop discussing this nonsense. Children are not at risk so there is no need to vaccinate. All vaccines against corona at the moment are much worse in terms of tolerance than the vaccines which are injected into the children during the various Uses. I will certainly not vaccinate my children with such a new and incompatible vaccine. As if vaccination was the only solution. I just hope the Indians renounce the WHO they bought.
