Yesterday’s FDA VRBPAC meeting was a big success, we got everything that we were hoping for within the scope of the meeting agenda:

1. Novavax is permitted to continue using a monovalent JN.1 target (1⬇️), which they showed is still inducing robust neutralizing antibody titers across JN.1 lineage strains, such as predominant LP.8.1 (2⬇️). The mRNA manufacturers are also permitted to target LP.8.1, if they wish.

2. There was lengthy and productive discussion about the idea of needing to move away from a seasonal approach to updating COVID vaccines, since COVID doesn’t fit into a seasonal box like viruses such as Influenza or RSV. Most of the committee was supportive of this shift and expressed their desire for future meetings to accomplish that goal. This would be important for getting vaccines available late in the summer, when children are returning back to school.

Next, it’s onto the CDC’s Advisory Committee on Immunization Practices (ACIP) meeting, which is likely going to be the tallest task of the season. They will be considering the implementation of Vinay Prasad and Marty Makary’s new framework for COVID-19 vaccination that seeks to limit access to people under the age of 65, so we need to push back hard against that and (3⬇️):

1. Pressure them to maintain universal recommendations for all ages without the consideration of underlying conditions.

We also want to maintain these 2 things:

2. The allowance to self-attest to immunocompromised status without documentation (cdc.gov/covid/vaccines…)

3. This broad list of underlying conditions that covers upwards of 70% of Americans (cdc.gov/covid/hcp/clin…)

ACIP is meeting on June 25-27th, and the public comment period will run from June 9th to June 20th.

For the next 17 days until public comment opens, take the opportunity to email the 17 ACIP voting members directly (4⬇️) and get them familiar with how much support there is for Novavax and for maintaining broad vaccine recommendations. As always, please remember to be respectful when reaching out.Based on the totality of the evidence, FDA has advised the manufacturers of the approved COVID-19 vaccines that to more closely match currently circulating SARS-CoV-2 viruses, the COVID-19 vaccines for use in the United States beginning in fall 2025 should be monovalent JN. 1-lineage-based COVID-19 vaccines (2025-2026 Formula), preferentially using the LP.8.1 strain.

CDC ADVISORY COMMITTEE ON IMMUNIZATION PRACTICES (ACIP) Meeting on June 25-27th Public comment period opens June 9th Some suggested talking points: 1. Maintain universal COVID-19 vaccine recommendations for all ages, which includes broadening Novavax BLA approval to allow access for all ages without underlying conditions. 2. Maintain the current COVID-19 vaccine guidelines for Moderately to Severely Immunocompromised People, allowing them to self-confirm immunocompromised status without documentation. 3. Maintain the current list of qualifying underlying conditions that have been shown to p...

Quick 🧵on the current state of Iota-carrageenan nasal sprays: Efficacy, safety, Betadine shortages, buying options for US & Can. markets.

I-C sprays are the only option on the market that have a real-world randomized, double-blind, placebo-controlled study backing them up. 1/14
This study assessed the use of an I-C nasal spray in 394 hospital personnel dedicated to care of COVID-19 patients. Out of 198 to receive placebo, 10 infections (5% incidence). Out of the 196 to receive I-C, 2 infections (1% incidence). 2/14

pmc.ncbi.nlm.nih.gov/articles/PMC84…
Other options, like Nitric Oxide (Enovid, VirX), Astodrimer sodium (Viraleze), ELAH (Covixyl), or Xylitol (Xlear) often appear promising, but to this point only have positive studies in vitro or positive studies that are not randomized, double blind, or placebo-controlled. 3/14

@idea_alchemist Damn, so this is how I find out that I also had fakes because my last box is certainly sparkley as hell. 1st is old/likely legit, 2nd is today, 3rd obviously fake. Imo there’s probably a bit of variation, bc it looks like mine from today has maybe a bit larger holes than yours?
@idea_alchemist However, I’ve also had ones with larger holes in the past. Here’s the one today (middle) next to 2 old boxes of valved 9211+. The bottom I suspected of being fake, only because the box came without the usual instruction pamphlet. Sketched me out enough that I never used them 1/2 Image
@idea_alchemist despite 3M having the “safe guard” code on this model which passed on both boxes. And now I see that those ones also have much smaller holes (but no sparkles), while the top has larger holes than the one today. 2/2
