What does the 2G rule bring in the fourth corona wave?

The first federal states are introducing the 2G rule.

This provides many corona freedoms only for vaccinated and convalescent people.

Can this prevent a fourth wave?

Kassel - The number of corona cases continues to rise in Germany *.

The RKI warns of a fourth wave that the vaccination rate is far too low to avoid overloading the clinics.

In order to keep the pandemic situation under control in autumn and winter, more and more experts are calling for the Corona * rules to be tightened from 3G to 2G.

Only those who have been vaccinated and those who have recovered would then have access to certain areas of public life throughout Germany; a negative test from non-vaccinated persons is then no longer sufficient.

For this, additional requirements, such as the occupancy limit, distance rules, and in some cases also the mask requirement, would be omitted.

It is questionable how useful the 2G rule is with regard to infection protection.

2G rule: effect on fourth corona wave questionable

Opinions on the subject differ.

While an ethics expert, according to the editorial network Germany (RND), warns of a division in society, the world medical president Frank Ulrich Montgomery called for 2G to be introduced nationwide.

The first federal states are already using the 2G model.

Baden-Württemberg, for example, wants to make the rule binding in the event of increasing hospital occupancy.

In Hamburg, too, people who have not been vaccinated can be excluded from events and restaurants, restaurateurs decide for themselves.

Does the 2G rule make sense?

After all, only a negative PCR test brings almost one hundred percent security against Corona.

According to Jan Fuhrmann, mathematician at the University of Heidelberg, the concrete impact of the 2G rule compared to the 3G rule can "hardly be estimated".

“In principle, it is already disputed among medical experts whether there is a greater residual risk of being contagious in the case of untested people who have been vaccinated and recovered or those who have not been vaccinated and who have tested negative.

That depends, among other things, on how long ago the vaccination or infection or the negative test happened, ”said Fuhrmann in an interview with the RND.

2G rule: Only a negative PCR test gives almost one hundred percent certainty

On the other hand, Hamburg's mayor Peter Tschentscher (SPD) justified the step towards the “optional” 2G rule with the fact that vaccinated and convalescent people had “no significant share” in the infection process. However, there are also reasons that call the argument into question: the spread of the delta variant, the increasing number of infections in the population and the declining vaccination effect in the elderly and people with weak immune systems. It is now clear that people who have been vaccinated become infected much more frequently than assumed a few months ago. The WHO is currently concerned about the new Corona variant "Mu" * from Colombia - which could also be dangerous for those who have been vaccinated.

If the PCR test is negative, the RKI assumes that an infection can be ruled out with almost 100% certainty.

And rapid antigen tests, with which unvaccinated people have mostly had access to date, must be able to rule out an infection with at least 80 percent probability.

2G-plus-G rule: Corona protection in sensitive areas

According to the modeler Fuhrmann, it would therefore make sense to minimize the risk of infection "in particularly sensitive areas" and to introduce a 2G-plus-G rule here.

“That would mean that you only allow vaccinated or convalescent people who can also show a current negative test.

Here, too, there is the problem, already known from 2G, that people who cannot be vaccinated for various reasons are automatically excluded, ”says Fuhrmann.

Opinions on the 2-G rule * also differ in the Kassel region.

This shows an HNA research.
