You think you are done, because a large part of the population has been vaccinated, but then the Coronavirus erupts again. This has happened in a number of countries, including Uruguay, Chile and Seychelles. De Volkskrant cites three reasons for this, from which we can also draw our lessons.
- Relaxes very quickly
Countries are working to lift the lockdown very quickly. Even before enough people have been vaccinated and before the virus really is gone. This requires a new wave of infection.
- Vaccines do not provide complete protection
Vaccines work great, but they are not 100% effective. In countries like Chile and Seychelles, Chinese AstraZeneca and Sinopharm bite a lot. These vaccines provide only 60 to 70 percent protection. People are no longer seriously ill anymore, but they still transmit the virus.
- Virus mutations throw a wrench into business
So far, vaccines have proven resistant to the British, Brazilian, South African and Indian variants of the virus, but they usually lose some of their effectiveness. As a result, the virus may erupt again.
