Dear MEL Topic Readers,
Covid: Double vaccinated can still spread virus at home
The good news is that those who are double-vaccinated for Coronavirus have a lower risk of getting infected by the highly infectious Delta variant. Also, even if they are infected, the symptoms are milder and lighter than those who aren’t vaccinated. The bad news is that they appear to be as infectious as unvaccinated people. So, if there are people who have been vaccinated and who have not been in a house or dormitory, those unvaccinated have a high risk of infection. That’s why the Delta variant is spreading violently even in countries where vaccination rates are high, like the UK. Another problem is that the point where we achieve herd immunity varies from disease to disease and variant to variant. It was originally thought 70% would achieve herd immunity against the coronavirus, but it was later found that the coverage needs be higher against new variants. It seems that social and health measures, such as mask-wearing, social distancing, and testing, remain essential even in vaccinated people at least for some time.
