Dr Ellie Murray on Twitter: “When relaxing infection precautions, its expected that risk among vaccinated increases, as is happening in UK & Israel. But the solution isn’t 3rd doses for vaccinated, it’s 1st & 2nd doses for unvaccinated!! More vaccines to more countries & in more arms should be our goal!!” / Twitter. (n.d.).
