Prof Carl Heneghan and Dr Tom Jefferson summarise what they've learned about the pharmacokinetics – how the body interacts with a drug – of the Pfizer vaccine and the 15 questions it leaves them with.
The withdrawal of the AstraZeneca Covid vaccine raises fresh questions about the failure of the MHRA to keep the public safe, say Prof. Carl Heneghan and Dr. Tom Jefferson.
Up to 2% of the population of England is autistic, according to the Nuffield Trust, while ADHD prescribing is up 50% in five years. What we have here is a serious case of overdiagnosis, say Carl Heneghan and Tom Jefferson.
