COVID-19 happened, and then the whole world needed a jab. In record time the world's big pharma companies created and rolled out slightly differing version of life-saving vaccines – all, let's not forget, at a cost.
This Spark compiles some of the biggest vaccine makers currently backed by the World Health Organization. Some are better known and more established than others, but all of these companies have vaccines in circulation. Remember – no vaccination will help your portfolio if you make a bad call, so ensure your research is in the best of health and do it yourself, don't take this for trading (or indeed, medical) advice.
