Why the virus flares up again in vaccinated countries – Wel.nl

You think you are done with it, because a large part of the population has been vaccinated, but then the corona virus flares up again. It has happened to a number of countries, including Uruguay, Chile and the Seychelles. De Volkskrant cites three reasons for this, from which we can also draw our lessons here.

  1. It relaxes too quickly
    Countries are lifting the lockdown too quickly. Even before enough people have been vaccinated and before the virus is really gone. That is asking for a new wave of infections.
  2. The vaccines do not provide complete protection
    The vaccines work great, but are not 100 percent effective. In countries such as Chile and the Seychelles, much is being stung with AstraZeneca and the Chinese Sinopharm. Those vaccines only offer 60 to 70 percent protection. People no longer become seriously ill, but still transmit the virus.
  3. Virus mutations throw a spanner in the works
    So far, the vaccines have proven to be 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 flare up a bit again.
