The new crown vaccine booster significantly increases the antibody response of rhesus monkeys

Science and Technology Daily, Beijing, October 24th (Reporter Liu Xia) American scientists wrote in the latest issue of "Science" that their research on macaques showed that injection of the new crown vaccine booster injection can enhance the neutralizing antibody in the macaques.

Scientists from the National Institutes of Health, Johns Hopkins University and other institutions said that about 6 months after the macaque was vaccinated with the first dose of the new vaccine, they were injected with the mRNA-1273 new crown vaccine booster, which is targeted at all known The concentration of neutralizing antibodies of the mutant strain of the new coronavirus will increase significantly

These data indicate that the booster needle will trigger a strong immune memory response, and may extend the duration of immunity

The researchers also determined that the mRNA-1273 vaccine developed against the original new coronavirus and the vaccine against the beta mutant strain of the new coronavirus are equivalent in enhancing the antibody response and providing protection

This study began six months ago, when the beta mutant strain was a global epidemic strain, so the researchers focused on this strain

They said that in humans, a dose of mRNA-1273 booster injection is expected to extend the protection period and effectiveness in response to respiratory infections caused by the epidemic new coronavirus strain
