The report was written by a team made up of 17 Chinese experts and 17 experts from other countries and international bodies such as WHO and the World Organization for Animal Health.
It considered four possible scenarios of how the pandemic started. It said a scenario where the virus spread via an intermediate animal host, possibly a wild animal captured and then raised on a farm, is “very likely.” That intermediate host may have been infected with the virus by a bat — considered the most likely original source — and then transmitted it to a human, but the report did not identify what animal that could have been.
Another possible-to-likely scenario is direct transmission from one of the animals known to carry a similar coronavirus, such as a bat or a pangolin.
Two other scenarios were considered unlikely. The report says introduction through cold food products is a “possible pathway” and introduction through a laboratory incident was considered to be “an extremely unlikely pathway.”
YOU ASKED. WE ANSWERED.
Q. Has the WHO ruled out a lab leak?
The team that wrote the WHO report also considered research done outside of China that found no evidence that the virus was engineered in a lab. Most independent research points to a natural origin for the virus.
However, the original mission of the WHO scientists was to study the animal origin of the novel coronavirus, which is why the new report does not provide the same depth of detail examining a lab leak. One of the investigators also said they did not do a “true forensic examination of a laboratory.”
WHAT’S IMPORTANT TODAY
Cautiously, Europe starts looking to Russia for vaccines
Europe’s vaccination campaign has been slow, mainly due to a lack of shots. That has prompted some leaders to look to Russia for possible help. French President Emmanuel Macron and German Chancellor Angela Merkel discussed possible vaccine cooperation with Russian President Vladimir Putin yesterday. According to a statement by the Elysée in Paris, the prospect depends on the assessment of the Sputnik V vaccine by the EMA.
Covid-19 PPE litter is killing wildlife
The researchers have so far recorded more than 50 incidences globally where wildlife was harmed, but they warned the actual number is likely to be far larger.
He should be on the frontline of the pandemic response. Instead, he is facing deportation
Microbiologist by training, Nigerian by birth, Charles Oti has spent four years working for the UK’s National Health Service as an infection control specialist. Oti’s skills are in short supply and among the UK government’s priorities for recruitment. But instead of taking a position on the front line of the pandemic response, he has been prevented from working and threatened with deportation.
Pfizer/BioNTech says its Covid-19 vaccine is 100% effective in adolescents
In a Phase 3 trial of 2,260 participants ages 12 to 15 in the US, the vaccine elicited strong antibody responses one month after the second dose — exceeding those demonstrated in people ages 16 to 25 in previous trials, Pfizer reported. The vaccine is currently authorized in the US for emergency use in people 16 and older.
ON OUR RADAR
- All 50 US states have announced when they plan to open up coronavirus vaccinations to everyone eligible under US Food and Drug Administration emergency use authorizations — if they haven’t done so already.
- Fewer Black people in the US have been vaccinated against coronavirus than White people, a fact often blamed on a decades-old unethical study. Experts say modern distrust is also at play.
- A dangerous Covid variant has wreaked havoc on Europe this spring. Health leaders fear the US could head the same way if authorities fail to act.
- Non-EU state Serbia has become the vaccine hub of the Balkans. The country has so many vaccine doses it can even offer shots to foreigners passing through.
- A vulnerable group fell through the cracks in the UK’s otherwise successful vaccine rollout. This doctor is working to change that.
- India is grappling with a surge in second wave cases. The country recorded 354 Covid-19 related fatalities yesterday, the highest death toll reported in a single day since December 17.
- Women have lost jobs at higher rates than men during the Covid crisis, and they’re being rehired at a slower rate as the economy bounces back. The World Economic Forum says attaining global gender parity will now take nearly 136 years.
