I am sharing below an explanatory video put out by Vox, an American news website, on a few issues associated with the vaccines that are available against COVID-19.
I saw this video in a post of my blog pal, Yamini MacLean.
This video tells us:
1) What is the meaning of a vaccine's efficacy rate; like when we say, for example, "This vaccine has an efficacy of 95%";
2) Why we shouldn't compare different brands of vaccines; and
3) What is the ultimate objective of the global vaccination programme.
A video worth watching and sharing with others, because there is so much misinformation surrounding various COVID-19 vaccines.
