With the COVID-19 vaccine rollout, the conversation about potential booster shots has been gaining traction. Recent updates from major pharmaceutical companies, including Pfizer and Moderna, suggest that booster shots may be on the horizon. According to Pfizer’s CEO, individuals could require a third dose before their first year of vaccination is complete, while Moderna is preparing to offer booster shots as soon as this fall.
Pfizer’s Booster Timeline
Pfizer is currently considering administering a third dose between six to twelve months after the second shot. CEO Albert Bourla indicated that people will likely need this additional dose within a year of being fully vaccinated, potentially leading to annual vaccinations akin to flu shots. “A likely scenario is that there will be a need for a third dose, somewhere between six and twelve months,” Bourla explained in an interview with CNBC on April 1, 2021, which was publicized later.
Moderna’s Plans for Fall
Moderna, on the other hand, has stated its intention to have a booster shot available by fall 2021. CEO Stephane Bancel emphasized the importance of ensuring that booster vaccines are accessible before the onset of the fall and winter seasons in the U.S. “I want to make sure there are boost vaccines available in the fall so that we protect people as we go into the next fall and winter season,” Bancel shared during a CNBC interview on April 14, 2021.
Johnson & Johnson’s Annual Vaccination
Johnson & Johnson’s CEO, Mike Stevens, hinted that annual vaccinations against COVID-19 might be necessary, although he did not provide as much detail as his counterparts from Pfizer and Moderna.
While studies and data regarding these booster shots are ongoing, Dr. Anthony Fauci has noted that more information is needed to determine when a booster will be necessary. Currently, there isn’t enough real-world data to pinpoint when vaccine-induced antibodies begin to decline. Fauci stated, “The way to get the answer is to follow people closely to see when the level of efficacy diminishes,” emphasizing the need for continuous monitoring.

Summary
With the potential for COVID booster shots approaching this fall, Pfizer and Moderna are preparing to administer these doses as early as six months after the initial vaccinations. Johnson & Johnson also hints at the need for annual vaccinations. Continuous studies will determine the exact timeline and necessity of these boosters.
