Pfizer is preparing to seek emergency approval for a COVID booster shot in August. As the U.S. fully reopens, vaccination rates remain a concern. With people gathering once again and removing their masks, new variants like the Delta variant, originally identified in India, are spreading rapidly. Although the vaccines available in the U.S. – Pfizer, Moderna, and Johnson & Johnson – continue to show strong efficacy, even against variants, there has been speculation about the need for booster shots to combat the pandemic. Pfizer has reported that immunity from its vaccine appears to be waning, prompting the development of a booster shot.
The company plans to release data on the effectiveness of a third vaccine dose and submit it to the Food and Drug Administration for emergency use authorization in August. “According to real-world data from the Israel Ministry of Health, we’ve observed a decrease in vaccine effectiveness in preventing both infections and symptomatic cases six months after vaccination, although the vaccine still effectively prevents severe illness,” Pfizer stated. “As the Delta variant becomes more prevalent, this trend aligns with our ongoing Phase 3 study analysis. While severe disease protection remains robust, we anticipate a decline in efficacy against symptomatic cases over time and the emergence of new variants. Given the data available, Pfizer and BioNTech suggest that a third dose may be advantageous within 6 to 12 months after the second dose for optimal protection.”
However, shortly after Pfizer’s announcement, the FDA and the Centers for Disease Control and Prevention issued a joint statement asserting that booster shots are not currently necessary for fully vaccinated Americans. “Those who have completed their vaccination regimen do not need a booster shot at this time,” they confirmed.
Pfizer has been diligently researching the safety and efficacy of its vaccines since their inception and possesses substantial data regarding the need for booster shots among those vaccinated. The contradiction from major health agencies could further exacerbate vaccine hesitancy, especially among the nearly half of eligible adults and teens who remain unvaccinated.
The World Health Organization also commented on the situation, stating, “We cannot determine whether booster vaccines will be necessary to sustain protection against COVID-19 until more data is gathered.”
Of the 158 million people vaccinated in the U.S., over half received Pfizer’s vaccine. For more insights on home insemination, check out our blog post here.

Summary
Pfizer is working on a COVID booster due to concerns that vaccine immunity is decreasing, but the CDC and FDA have stated that boosters are not currently needed for the fully vaccinated. This discrepancy might contribute to vaccine hesitancy among the unvaccinated population.
