Why RFK Jr’s Cancellation of Moderna’s Pandemic Flu Vaccine is Nonsensical Raywat / blog, COVID-19, epidemiology, politics / 0 comment

I'd already written about the foolhardiness of RFK Jr cancelling mRNA flu jabs. Now he's defunded the entire platform. This will bite the US hard on the ass, both in terms of health outcomes and long term bioscience-based prosperity. Re-upping from June:

Covid numbers are rising and we trying to get the word out. Here are the first two billboards so far this summer and I’ll be working to keep putting them out well into the fall.
If you want to help me continue the campaign any help is appreciated.

Sadly we’ve known for years now that SARS-CoV2 has a negative impact on placental health. Asymptomatic infections are not discussed and No one seems to care. Maybe because it damages the brain also. Humanity is not in a good place.

If you or someone you love is pregnant, it is so important for the health of your baby to avoid COVID exposure/infection. Masks can help you stay well. Wear secure-fitting N95s, KN95s or KF94s all the time when outside the home. Avoid crowds. Don't spend time with sick people. #MaskUp #WearAMask

Cord blood cytokines/chemokines linked to delays in toddlers exposed to SARS-CoV-2 prenatally - Pediatric Research Pediatric Research - Cord blood cytokines/chemokines linked to delays in toddlers exposed to SARS-CoV-2 prenatally

Looking at the impact of maternal COVID infection on neurodevelopment, the authors found: at 6 months, 33.3% of infants exhibited cognitive delays, 20% communication delays, and 40% motor delays, increasing to 35.71%, 64.29%, and 57.14% at 24 months, respectively.

International support welcome, too.

With US OSHA being sidelined, this standard from Canadian Standards Association could fill a major international leadership gap. Airborne disease needs airborne workplace safety. Including in healthcare!

It could be argued that influential individuals in public health and associated departments and organisations are currently involved in professional protectionism. After spending years creating the impression covid infections are benign in children they are in a position where a change in messaging now will lead to difficult questions being asked of those who have consistently presented infection in children as benign.

"In these circumstances, where you have an unprecedented measles outbreak and you have the lives of children on the line, sometimes, that's the tipping point," he said.

As the measles outbreak worsens, more Canadians demand mandatory school vaccinations because unvaccinated children are driving this outbreak.

Enough with the discussions. The solution is political - Feds and provinces must make vaccines mandatory.

Canada needs to fix its massive measles outbreak and the solution is simple:

mandatory school vaccines - no more conscience/religious exemptions.
