Why does the virus break out again in vaccinated countries – Wel.nl

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.

1. 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.
2. 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.
3. 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.
