- Debating the possible origins of COVID-19: A lab-escaped bioweapon? Animal poop? Random mutations of an existing virus?
Considered a conspiracy theory just a year ago, the possibility that SARS-COV-2 was leaked from a laboratory is now a serious hypothesis, alongside the idea that the virus naturally evolved and jumped from other animals to humans. This status change for the so-called “laboratory spillover” explanation was prompted by a China–WHO joint study released in early 2021. The 313-page investigation dedicated just four pages to the possibility of a lab accident, prompting 16 scientists to call for a more thorough examination of how the virus arose:
We must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data. A proper investigation should be transparent, objective, data-driven, inclusive of broad expertise, subject to independent oversight, and responsibly managed to minimize the impact of conflicts of interest. Public health agencies and research laboratories alike need to open their records to the public.
Why do some vaccine-hesitant Americans ultimately get their COVID shots? For some it’s a simple matter of getting to attend baseball games again, while others worry that they won’t be able to care for their children if they get infected. Whatever their motivations, their stories could offer insights to public health officials eager to convince even more vaccine skeptics to come around.
The CDC’s and FDA’s decision to pause distribution of Johnson & Johnson’s COVID-19 shot had a noticeable impact on vaccine uptake. Moreover, immunization skeptics used the confusing messaging (if the shot is safe, why “pause” it?) to spur their cause, creating a sort of negative feedback loop of vaccine hesitancy. Was the pause necessary, and what can we learn from the ensuing controversy before we face new infectious disease threats in the future?
