1 year ago today, @DrTedros declared that the outbreak of #COVID19 constituted a Public Health Emergency of International Concern, the highest level of alarm 🚨 under international law.
By that time, WHO was already working closely with countries, sharing life-saving information on how to prepare and protect their people against #COVID19.
Less than 2 weeks after the first alerts about #COVID19, WHO published a set of advice to countries. We shipped test kits to labs around the 🌎🌍🌏.

Throughout 2020, WHO sent lifesaving supplies & equipment & reached billions of people around the 🌏🌍🌎 with vital information about how to protect themselves from #COVID19.

Protecting #HealthWorkers is one of our top priorities.
WHO established the #COVID19 Supply Chain System to address shortages, ensure quality & help countries get vital safety equipment.

Medical oxygen saves #COVID19 patients’ lives.
By December 2020, WHO had sent more than 16 500 oxygen concentrators and 40 000 pulse oximeters & oxygen monitors to 121 countries.

Through #OpenWHO, millions of people took free online courses to learn more about safely responding to #COVID19

In 2020, WHO provided technical support, virtual training, equipment and supplies to boost #COVID19 testing capacity around the 🌎🌍🌏

WHO and partners have worked with scientists, donors and manufacturers from across the globe to speed the development of vaccines against #COVID19.

As we enter the second year of the #COVID19 outbreak & pass 100 million cases, the focus must be on working together.

To end the pandemic we must achieve #VaccinEquity. Let’s share vaccines, therapeutics and diagnostics fairly around the 🌎🌍🌏

Here are three main approaches to designing a #COVID19 vaccine:

1⃣ the whole-microbe approach
2⃣ the subunit approach
3⃣ the genetic approach (nucleic acid vaccine)

Learn more πŸ‘‰bit.ly/3caqsDW Image
The whole-microbe approach uses a whole virus/bacterium to design a vaccine. It can be divided in 3 categories:

1⃣ Inactivated vaccine (how flu & #polio vaccines are made)
2⃣ Live-attenuated vaccine
3⃣ Viral vector vaccine (how #Ebola vaccine is made)

πŸ‘‰bit.ly/3caqsDW Image
The subunit approach uses the parts of the germ (or microbe) that triggers the immune system.

Most of the vaccines on the childhood schedule are subunit vaccines. Learn more πŸ‘‰bit.ly/3caqsDW Image

How is a vaccine approved for production❓

1⃣ Pre-approval stage following clinical trials
2⃣ Regulatory assessment & approval
3⃣ WHO prequalification & approval
4⃣ Ready for production

Making vaccines available can take a long time, even when there’s a health emergency like #COVID19.

How is a vaccine made❓

Typically, companies will work to complete clinical development plans for a vaccine. Once authorized, manufacturing begins to scale up.

#COVAX will also boost development capacity & ensure equitable distribution of vaccines.πŸ‘‡bit.ly/3675hhZ

The international team working to understand the origins of the #COVID19 virus completed its 2-week quarantine in Wuhan, #China on Thursday. As members start their field visits on Friday, they should receive the support, access and the data they need.
While in quarantine, the team had daily virtual meetings with Chinese scientists, who shared updates on relevant #COVID19 studies done in #China plus other information and experiences. The team made requests for detailed underlying data, among other things.
All hypotheses are on the table as the team follows the science in their work to understand the origins of the #COVID19 virus. The team will have their first face-to-face meeting with Chinese scientists on Friday and then begin field visits in and around Wuhan, #China.
