As the COVID-19 vaccine rollout continues, discussions regarding potential booster shots have gained momentum. Recent updates from pharmaceutical companies indicate that booster shots may soon be on the horizon. Pfizer’s CEO suggests that individuals may require a third dose of the vaccine within a year of their initial vaccination, while Moderna is preparing to administer booster shots as early as this fall.
Pfizer’s Plans for a Third Dose
Pfizer is considering a third dose to be given “between six and twelve months” following the second dose. According to CEO Albert Bourla, it is likely that individuals will need this additional shot within a year of being fully vaccinated, potentially leading to annual vaccinations, similar to flu shots. “A likely scenario is that there will be a need for a third dose, somewhere between six and twelve months, and then annual revaccination,” Bourla mentioned in an interview with CNBC.
Moderna’s Booster Shot Timeline
Meanwhile, Moderna’s CEO, Sarah Kim, stated that the company is aiming to have its booster shot ready for distribution this fall. “I want to ensure that boost vaccines are available in the fall to protect individuals as we approach the next fall and winter season in the U.S.,” Kim said, emphasizing the importance of getting these shots prepared in advance.
Johnson & Johnson’s Position
Johnson & Johnson’s CEO, David Lee, has also hinted at the possibility of requiring annual vaccinations for COVID-19, although he has provided fewer specifics than his counterparts.
Research and Efficacy
Currently, research is ongoing to determine the efficacy and timing of these booster shots. Dr. Anthony Fauci has reiterated the need for more data to understand when vaccine-induced immunity begins to wane. He noted, “The way to get the answer is to follow people closely enough to determine when that level of efficacy diminishes.” As of now, vaccines appear to maintain protective antibody levels for at least six months.
