Vaccines don't stop spread of Covid

Almost everyone in Portugal has been vaccinated and the country has one of the highest rates of Covid cases in the world. 

The jab doesn't stop you getting Covid, they say now, but it improves your chance of surviving it. So they say now but not 6 months ago, when Politico said “vaccination is the main determinant of whether a country can keep cases down". The number of deaths from Covid in Portugal and throughout Europe is now very low. 

As for herd immunity that doesn't seem to happen with Covid-19 unlike other infections. Because it was invented in a Chinese laboratory, perhaps.
