New evidence shows Pfizer and Moderna vaccines are superior … 10 times stronger immunity

There is a huge gap in the amount of antibodies that mRNA-based vaccines and those that follow the traditional method of inactivating the virus that causes Covid-19 can generate, according to a study conducted in Hong Kong in the United States. latest discovery on the mixed results after mass vaccinations using different types of vaccines.

The research, published Thursday in the prestigious scientific journal The Lancet, found that antibody levels in Hong Kong health workers who were fully vaccinated with the mRNA vaccine from German company BioNTech and its US partner Pfizer are about 10 times higher than those seen in recipients of the inactivated vaccine. From Chinese Sinovac.

The difference in the concentrations of neutralizing antibodies identified in the study could translate into substantial differences in the effectiveness of the vaccine, the researchers said.

This discovery adds to a growing body of evidence indicating the superiority of biotechnology mRNA vaccines in providing strong and comprehensive protection against the Covid-19 virus and its variants, compared to vaccines that followed more traditional methods such as vaccines. with inactivated viruses.

Areas of Israel in the United States that depended primarily on mRNA vaccines from Pfizer Inc and its German partner BioNTech, as well as the American company Moderna, have seen marked decreases in infections. In contrast, countries that primarily used inactivated vaccines from Sinovac and Sinopharm in China did not experience the same drop in the number of cases, even though use of both types significantly prevented more severe COVID-19 symptoms by more deaths.

The low efficacy of inactivated vaccines has prompted countries from Thailand to the United Arab Emirates to offer another booster to those already vaccinated as the most contagious delta mutant fuels a resurgence of the epidemic.

The Hong Kong study also suggested that future research could examine how booster doses increase antibody levels and protection in people vaccinated with conventional vaccines.
