3 Vaccines Protect against COVID-19.


Too much histamine or prostaglandin D2 signaling or too little interferon signaling lead to increased risk for severe COVID-19.

Fear of the unknown and comfort with risk

  • A fraction of infected people will become desperately ill or even die, but we have no way of knowing who those people are in advance.
  • No universally effective treatment is available for those who will become severely ill with COVID-19, so we don’t know if treatment will…
