2. Stopping their healthcare system collapsing:
When COVID-19 cases surged, many countries struggled not to let their hospitals, clinics, and doctors, etc., get completely overwhelmed. Think of how difficult it was to get a hospital bed at one point during the pandemic.
3. Approving vaccines fast enough:
Countries also had to find ways to get approval for new vaccines, and then to administer vaccines at never before seen speeds.
4. Communicating reliable health information to communities:
Because of constantly evolving scientific knowledge and health guidance, and how common false news was, it became a major challenge to reliable health information to communities.
5. Community concerns and unanswered questions:
People worried about the impact of the recommended health behaviours and policies. These concerns made communicating reliable health info even harder.
