Assuming these #COVID-19 vaccines provide long-lived protection (if you remember, just 2-3 months ago, there were questions about how long until reinfection can happen again after being infected), there are nearly 8 billion people in the world, and we need to get high (80%+) rates of vaccination everywhere. Until every village in Zimbabwe is vaccinated, there is still a chance for #SARS-CoV-2 or a closely related #coronavirus to reach out and take a bunch of lives.
