A booster shot of the COVID-19 vaccine made by Pfizer and BioNTech strongly extends protection, a new study from the companies shows, and they are developing a vaccine targeted directly at the Delta variant, which first arose in India.
The companies say they have demonstrated that a third dose of their vaccine, given six months after the second, increases neutralizing antibodies five to tenfold against the original virus and the so-called Beta variant, which was first identified in South Africa. The booster was also found to be safe. They plan soon to publish this data and submit it to the Food and Drug Administration for authorization. Everyday there is a new theory and idea. How much money will be made if a new booster is found to be needed?
Neither the companies nor the government recommend booster shots yet, until their safety and effectiveness can be fully explored. In a joint statement late Thursday, the FDA and the Centers for Disease Control and Prevention emphasized that people who have been fully vaccinated do not need booster shots yet.
