Vaccines This article reports that the World Health Organization’s COVAX project declined to approve Medicago’s vax — not because their vax doesn’t work, but because Medicago is largely owned by Big Tobacco, and that’s verboten.

Vaccines This study found that countries which use the Inactivated Polio Vaccine (IPV) have a higher rate of COVID-19 than those which use the Oral Polio Vaccine (OPV), which uses a live attenuated virus. OPV is easier/cheaper to administer, but there is a (small) risk of getting polio from the vaccine. Yes, countries which use… Continue reading 2022-03-20/21 General
