A randomized controlled trial (RCT) is the gold-standard method for testing the safety and efficacy of a drug or biologic in humans. Because of RCTs, we know that the Covid-19 vaccines are safe and effective compared to the control group.

Beyond the clinical trial’s control group in the general population…

Hi everyone! I have here another monthly update from Microbial Instincts, an independent publication about microbes and vaccines.

But first, as most have already heard, the World Health Organization (WHO) has named the B.1.1.529 variant as Omicron last week, which was first detected in South Africa in a sample dated…

The Medicines and Healthcare products Regulatory Agency (MHRA) of the U.K. has recorded 32,036 individual cases of post-vaccine menstrual disorders — out of 49.4 million Covid-19 vaccine doses — as of 27 October 2021.

Whereas traditional vaccine technology — such as inactivated, protein-based, and live-attenuated vaccines — has been used to combat infectious diseases for decades.


Hi everyone! Here’s another monthly update from me on what’s going on in Microbial Instincts, an independent publication about infectious diseases and vaccines. As usual, here are short notes of the articles (friend linked) published in October 2021 that I hope will keep you scientifically informed:

COVID-19 Pandemic

A few researchers have previously raised the hypothetical concern of the Covid-19 mRNA vaccine, encapsulated in lipid nanoparticles (LNPs), entering the brain, given that LNPs can be used to deliver medical drugs across the blood-brain barrier (BBB) into the brain.

I detailed this issue in detail in “Concerns of Lipid…

The majority of Covid-19 cases are now coming from vaccinated people in several parts of the world with high vaccination rates. Calling it a pandemic of the unvaccinated as we used to is no longer appropriate. Even though the Covid-19 vaccines still work, it is now a pandemic of both…
