FDA Poised to Approve Updated covid 19 vaccines Amid Surge
FDA Decision Expected Soon
The US Food and Drug Administration (FDA) is on the verge of approving updated covid 19 vaccines as early as next week, according to sources familiar with the situation. This potential greenlight comes as the country grapples with its largest summer wave of Covid-19 in two years.
The updated vaccines from Moderna and Pfizer/BioNTech, targeting the recently circulating KP.2 strain of the virus, are anticipated to receive FDA authorization. The approval could be issued ahead of last year’s vaccine, which was approved on September 11. However, it remains unclear if Novavax’s updated vaccine, designed to target the JN.1 strain, will receive simultaneous approval.
Current Covid 19 Situation
As the US faces a significant summer surge in Covid 19 cases, the timing of this vaccine approval is critical. The CDC reports that the virus’s levels in wastewater are at “very high” levels nationally, marking the highest summer peak since July 2022. This data indicates a significant increase in the virus’s presence across the country, a trend that is contributing to the current wave of infections.
Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, highlighted the urgency of vaccination in light of this surge. Osterholm recently received the previous season’s vaccine to bolster his immunity and plans to wait four months before getting the new vaccine, in line with health recommendations.

Vaccine Readiness and Availability
Both Pfizer and Moderna are prepared to distribute their updated vaccines promptly upon FDA approval. Pfizer and Moderna representatives have assured that they have sufficient supply and expect the new covid 19 vaccines to be available in stores shortly after authorization. Moderna’s spokesperson indicated that the vaccines could be on shelves within days of receiving the greenlight.
In contrast, Novavax’s covid 19 vaccines , which employs protein technology, has a longer manufacturing timeline compared to mRNA vaccines. Novavax has indicated that its updated vaccine should be ready for distribution by the end of August, pending authorization. The company’s executives have projected that the vaccine will be available in warehouses this month, but a spokesperson for Novavax did not provide immediate comment.
Health Recommendations
The CDC’s June recommendation advised everyone over six months of age to receive both an updated Covid 19 vaccine and a flu shot this year. This guidance underscores the importance of dual protection against respiratory illnesses as the flu season approaches and Covid-19 continues to circulate at elevated levels.
Virus Variants and Impact
The current predominant strain in the US is KP.3.1.1, which has surged to account for 37% of cases over the past two weeks. This strain, along with KP.2 and the JN.1 strain targeted by Novavax, is a variant of the Omicron lineage. These strains have driven recent waves of infection due to their ability to partially evade immunity from previous infections and vaccinations.
Hospitalization and Severe Disease
While there has been an increase in hospitalizations and severe disease metrics, these rates are not as high as those observed during previous waves of the pandemic. The rising numbers are attributed to both waning immunity and the emergence of new variants. Despite this increase, the current situation is manageable compared to earlier, more severe phases of the pandemic.
Future Outlook
As the FDA prepares to make a decision, the availability of updated vaccines is expected to play a crucial role in managing the ongoing covid 19 vaccines surge. The updated vaccines are designed to provide enhanced protection against the circulating strains and help mitigate the impact of the virus during this period of high transmission.
Conclusion
The potential approval of updated covid 19 vaccines by the FDA represents a significant step in addressing the current surge and preparing for the upcoming flu season. With the virus continuing to spread and new variants emerging, the timely availability of these vaccines will be essential in bolstering public health efforts and controlling the pandemic’s impact.
