Scott Gottlieb, former director of the FDA and director of Pfizer, said on the 21st that people do not need to update the vaccine every season after they receive the new crown vaccine, but only need to give additional injections every two or three years.
Scott Gottlieb, former director of the U.S. Food and Drug Administration (FDA) and director of Pfizer, said on the 21st that because the surface proteins of the Chinese virus (surface proteins) will evolve over time, making antibodies unrecognizable, but people do not need to update the vaccine every season after they get the new crown vaccine, but only need to give additional shots every two or three years.
In an interview with CNBC News, Gottlieb said the successful vaccine for the Chinese Communist virus and the antibodies it has produced will help protect against the new variant of the Chinese Communist virus that is raging in the United Kingdom, but because the virus will continue to evolve, it still needs to be monitored closely.
He said, “I said about six months or eight months ago that the CCP virus vaccine would only need to be administered in additional doses every two or three years, and that has not changed so far.”
He pointed out that the vaccine does not need to be updated every season, “but if it becomes very easy in terms of technology, perhaps it can be considered to do so, when you can see which strains of the virus are prevalent and regularly make a relative response in terms of the vaccine.”
British Prime Minister Boris Johnson (Boris Johnson) warned that a variant of the Chinese Communist virus is 70 percent more infectious than the original Chinese Communist virus.
Gottlieb said that although the variant CCP virus may be more infectious, there is no sign of mutations in the surface proteins, and the variant CCP virus will not therefore evade the CCP virus vaccine or the defense of antibodies already produced.
But Gottlieb also said that a possible situation is that the surface protein of the CCP virus will mutate, and the mutation result is not detected by the current antibodies, “and then we will have to update the vaccine.
He noted that the vaccine, which uses all of the virus spike protein, could have a polyclonal response effect that would prove beneficial in the end.
He said, “We are generating antibodies against different parts of the spike protein, and even if there is a mutation in one part of the protein that makes some of the antibodies unrecognizable, there are still antibodies against other parts of the protein.”
