More and more countries doubted the effectiveness of Chinese inactivated vaccines. A study conducted in Hong Kong on more than a thousand patients shows that the coronavirus vaccine, developed by the Chinese laboratory Sinovac, produces ten times less antibodies than the vaccine developed by Bioendech and manufactured by Pfizer. In recent months, many countries that have largely immunized their populations with Chinese inactivated vaccines have faced major waves of epidemics. These vaccines, on the other hand, seem to be satisfactorily effective in preventing severe forms of Govt-19.
This comparison between the two vaccines available in Hong Kong was obtained by researchers at the University of Hong Kong in two doses of the vaccine for 1,442 health workers. Published in the medical journal Lancet Microbiology, July 15, The article notes that the level of antibodies is not sufficient to assess the level of immunity provided by a vaccine, but it “Differences in the concentrations of neutralizing antibodies identified in our study may cause significant differences in the effectiveness of the vaccine.”. Researchers say that patients who receive coronavirus show similar antibody levels to patients who have been diagnosed with Covit-19.
This further strengthens the evidence for the particularly high efficacy of messenger RNA vaccines compared to traditional technologies such as inactivated viruses. However, the latter have advantages: they can be stored in simple refrigerators, while the Pfizer-Bioentech vaccine requires a temperature of minus 70 degrees to be stored for more than a month, which is a barrier to its use in many developing countries.
In recent months, despite high vaccination rates, many countries have experienced significant levels of pollution: this is particularly the case in the United Arab Emirates, the Seychelles, Mongolia, Chile and Uruguay, where their people have been vaccinated mainly by synovial and synoform injections, two of which are by Chinese manufacturers Use passive virus technology. Each time, the cause of death is undetected, but the spread of the virus seems to be faster than in countries that have been widely vaccinated with a messenger RNA solution, as in the case of Israel, which provided the Biotech vaccine to its people.
