Police turned back about 100 cars and fined two at travel-denying checkpoints. Those two just… didn’t stop. Vaccination I… Continue reading 2021-05-22/23/24 BC

Vaccines SinoVac/CoronaVac did a clinical trial in kids down to age 3. They found that compared to adults, the kids had better immune responses and fewer side-effects. They also tested full-doses vs. half-doses, and while a half-dose might be enough for the smallest kids, it interestingly didn’t make the side-effects any better. That surprised me:… Continue reading 2021-05-20 General
