This is unthinkable, unethical, a terrible violation. We make a solemn vow to our study participants- to care for their safety in return for their volunteerism for humanity. I’ve done trials for 4 decades. We CANNOT do this. —->nytimes.com/2025/02/06/hea… via ⁦The New York Times

The Imminent Threat to US (and global) Public Health: the proposed reductions and interference in US government health agencies such as FDA, NIH, CDC, and programs such as PEPFAR and USAID. Recommend calling your members of Congress. Use the “5 calls” app. wsj.com/health/healthc…

I am happy to see more scientists back here on X (aka Twitter) commenting and engaging with the community. This is the #1 lesson for all of us from everything that is happening these days: Researchers/Scientists cannot retreat to their own little echo-chambers. They have to

#1 Dear Florida, Please do not do this. Do not be naïve. Think of this: We would not send a group of new and untrained firefighters out to battle against a blaze. Why would we send our children out into the world with untrained (naïve) immune systems? Firefighters need training .

#2 Dear FL, Without vaccine mandates, your vaccination rates will fall below the herd immunity thresholds for diseases. For example, measles is so highly contagious that 95% of people must be vaccinated to achieve herd immunity. FL vacations will become dangerous for us. Love, GA

Dear Alabama - please do not copy Florida,which is considering putting children’s lives at risk in exchange for political gain——>RFK Jr. allies claim momentum as Florida targets vaccines: ‘Fight is coming’ washingtonpost.com/health/2025/09…

#4 Dear FL, Think of this: Without vaccine mandates, vacationers and retirees will decide to stop visiting and retiring in contagious Florida. Your economic metrics will fall as your infectious disease rates rise. Florida: please don’t be naïve, be vaccine-experienced, be safe.

#5 Dear FL, Without vaccine mandates your communities will lose immunity. Naïve (unvaccinated) children will suffer, miss school, incur medical expenses. The immense cost-effectiveness of vaccines will be lost. Florida: don’t be naïve.
