Professor Jonathan Van-Tam, Britain's assistant chief medical officer, has warned that a person can still spread the virus after being vaccinated against the coronavirus. And so he advised complying with the lock down.
In an interview with the British newspaper The Telegraph, Professor Van-Tam said: "Scientists do not yet know the effectiveness of vaccines in preventing infections. Everyone has to follow the hygiene rules whether they are vaccinated or not. No vaccine is 100% effective. So resistance cannot be fully guaranteed. '
Professor Van-Tam added, ‘Some people can become infected with the virus even two to three weeks after receiving the vaccine. So it's best to wait at least three weeks for older people to develop immunity to the virus.
