There is already research showing that vaccines with broad neutralizing power can be designed.
From 2003 with the initial outbreak of the SARS-CoV virus, which was checked in time before a pandemic occurred, Several researchers have studied the origin of this very special class of coronaviruses.
Researchers in China and other parts of the world, collecting specimens from various species, have found that these coronaviruses are very common in bats and other animals., in which they do not appear to cause particular health problems.
With the SARS-CoV-2 pandemic it became clear that the class of these viruses could potentially be the source of pandemic waves. One solution to avoid future pandemics would be to develop broad-spectrum vaccines, that is, they will be able to block a wide range of coronaviruses in this category.
The Professors of the Medical School of the National and Kapodistrian University of Athens, Gikas Majorkinis and Thanos Dimopoulos (Rector of EKPA) report that pan-coronary vaccines will be able to stop a pandemic from a completely different strain of the coronavirus class, but also to limit the arrival of a wave from a mutant strain of SARS-CoV-2.
Hopes for a vaccine to treat all coronaviruses are not theoretical
Hopes for such a vaccine are not theoretical. There is already research showing that vaccines with broad neutralizing power can be designed. First in studies performed on patients infected with the Beta strain (known as South African) It became apparent that the immune response to the Beta strain could just as well neutralize the Gama strain.
More recently, A study published in the New England Journal of Medicine showed that people who were infected with SARS-CoV before about 18 years, when vaccinated for SARS-CoV-2 developed antibody responses that could satisfactorily neutralize a wide range of coronaviruses, both the mutated Alpha strains, Beta and Delta, as well as strains that infect bats and pangolins.
Although the mechanism of production of this broad-spectrum immune response is not fully understood, It seems that immunization with an appropriate combination of antigens that have an evolutionary distance has contributed to the result.
A second element that is extremely important is that the immune memory from the initial infections has been maintained at a satisfactory level even after 18 years, as exposure of the immune system to a related virus mobilized cells already trained by SARS-CoV to produce enhanced immune responses.
In each case, they have seized it, despite obstacles we can scarcely imagine. ".
