The US Centers for Disease Control and Prevention reported,CDC“The protection offered by coronavirus vaccines diminishes over time, especially for people 65 and older.
According to the website,CNNResearcher Ruth Link-Gillis, who helps lead the CDC’s Vaccine Effectiveness Team, reviewed a series of studies looking at the overall effectiveness of vaccines in different groups of people between February and August and found similar patterns to the Pfizer and Moderna vaccines, both of which are made using Pfizer and Moderna technology. mRNAOr the DNA of the Corona virus.
The findings tend to support the argument that people’s protection begins to wane after a few months, and that booster vaccines may help restore their immunity.
Vaccines’ effectiveness began to wane a few months after people received their full vaccinations – which is defined as two weeks after the second dose of any vaccine.
Link-Gillis said at a meeting of CDC vaccine advisers (CDC): “For individuals over 65 years of age, we have seen a decrease in vaccine efficacy against infection with the Pfizer Moderna vaccines.”
“We’ve also seen a decline, especially for the Pfizer vaccine, for people 65 and older, which we don’t see in the younger groups,” she added.
The Centers for Disease Control and Prevention’s Immunization Practices Advisory Committee (ADC)CDC) met yesterday, Wednesday, to discuss the possible need for booster doses of vaccines.
The FDA has issued an emergency use authorization for Pfizer’s booster vaccines for people 65 and older with underlying conditions that put them at risk of serious illness, and for people whose jobs put them at risk.
The CDC said the efficacy of the Moderna vaccine is generally higher than that of the Pfizer vaccine, and for Johnson’s vaccine, the efficacy of the vaccine actually increases over time, even after the delta variant has dominated.
