The default answer for most scientists has been that the virus, SARS-CoV-2, probably made the jump to humans from bats, if it was a direct spillover — or, more likely, through one or more intermediate mammals. MCKEEVER A (6 April 2021). "We still don't know the origins of the coronavirus. Here are 4 scenarios".
The COVID-19 lab leak theory, or lab leak hypothesis, is the idea that SARS-CoV-2, the virus that caused the COVID-19 pandemic, came from a laboratory. This claim is highly controversial; most scientists believe the virus spilled into human populations through natural zoonosis (transfer directly from an infected non-human animal), similar to ...

Ioannidis (/ ˌ iː ə ˈ n iː d ɪ s / EE-ə-NEE-diss; Greek: Ιωάννης Ιωαννίδης, pronounced [i.oˈanis i.oaˈniðis]; born August 21, 1965) is a Greek-American physician-scientist, writer and Stanford University professor who has made contributions to evidence-based medicine, epidemiology, and clinical research.
Inactivated vaccine. An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then killed to destroy disease-producing capacity. In contrast, live vaccines use pathogens that are still alive (but are almost always attenuated, that is, weakened).
The item went on to explain that a rare risk of myocarditis appears to be higher following a COVID-19 infection, citing a study that found that boys and young men infected with the virus are up to ...
How COVID‑19 vaccines work. The video shows the process of vaccination, from injection with RNA or viral vector vaccines, to uptake and translation, and on to immune system stimulation and effect.

Robert Ray Redfield Jr. [1] [2] was born on July 10, 1951. His parents, Robert Ray Redfield (1923–1956, from Ogden) and Betty, née Gasvoda, [1] were both scientists at the National Institutes of Health, [3] where his father was a surgeon and cellular physiologist at the National Heart Institute; [1] Redfield's career in medical research was influenced by this background.
