The Centers for Disease Control and Prevention and the FDA issued a joint statement July 9 that vaccine boosters are not needed at this time.
Those who remain unvaccinated make up nearly all hospitalizations and deaths, they say.
The statement reads:
"The United States is fortunate to have highly effective vaccines that are widely available for those aged 12 and up. People who are fully vaccinated are protected from severe disease and death, including from the variants currently circulating in the country such as Delta. People who are not vaccinated remain at risk. Virtually all COVID-19 hospitalizations and deaths are among those who are unvaccinated. We encourage Americans who have not yet been vaccinated to get vaccinated as soon as possible to protect themselves and their community.
"Americans who have been fully vaccinated do not need a booster shot at this time. FDA, CDC, and NIH are engaged in a science-based, rigorous process to consider whether or when a booster might be necessary. This process takes into account laboratory data, clinical trial data, and cohort data – which can include data from specific pharmaceutical companies, but does not rely on those data exclusively. We continue to review any new data as it becomes available and will keep the public informed. We are prepared for booster doses if and when the science demonstrates that they are needed."
On July 8, Pfizer and BioNTech issued a statement that they "have seen encouraging data in the ongoing booster trial of a third dose of the current BNT162b2 vaccine. Initial data from the study demonstrate that a booster dose given 6 months after the second dose has a consistent tolerability profile while eliciting high neutralization titers against the wild type
and the Beta variant, which are 5 to 10 times higher than after two primary doses."
They say, "the Delta variant is becoming the dominant variant in Israel as well as many other countries."
According to Yale Medicine, the Delta variant is highly contagious and possibly more severe and is now the dominant strain of COVID-19 in the United States.
