In light of rising COVID-19 cases and the spread of new variants, Pfizer is preparing to request emergency authorization for a COVID booster shot in August. As the U.S. resumes normal activities, vaccination rates have not reached ideal levels, leading to concerns about the Delta variant, which originated in India and is rapidly becoming prevalent. While vaccines from Pfizer, Moderna, and Johnson & Johnson continue to provide robust protection, Pfizer has noted signs that immunity from its vaccine may be waning.
The company plans to release data on the effectiveness of a third vaccine dose and will submit this information to the Food and Drug Administration (FDA) for emergency use authorization. Pfizer stated, “Data from the Israel Ministry of Health shows that vaccine effectiveness in preventing infection and symptomatic disease has decreased six months after vaccination, although protection against severe illness remains strong.” They suggest that a third dose may help sustain high levels of protection within 6 to 12 months following the second dose.
However, shortly after Pfizer’s announcement, the FDA and the Centers for Disease Control and Prevention (CDC) released a statement asserting that booster shots are not currently necessary for fully vaccinated Americans. They emphasized that the decision about booster shots should rest with public health officials rather than private companies.
This conflicting information could exacerbate vaccine hesitancy, especially as nearly half of eligible adults and teens remain unvaccinated. The World Health Organization (WHO) also commented on the uncertainty surrounding the need for booster vaccines, stating, “We don’t know whether booster vaccines will be needed to maintain protection against COVID-19 until additional data is collected.”
Out of the 158 million people vaccinated in the U.S., more than half received the Pfizer vaccine.

Summary:
Pfizer is preparing to request authorization for a COVID booster shot due to signs of waning immunity, while the FDA and CDC assert that boosters are not needed at this time. This contradiction may contribute to vaccine hesitancy among the public. The WHO also highlighted the uncertainty surrounding the necessity of booster vaccines, emphasizing the need for more data.
