And it’s attacked again cos COVID-19 wasn’t effective, with COVID-20. The reason there’s a “19” at the end is because the first 18 were less effective.

The Chinese brands, don’t work and only make the symptoms worse, however Pfizer, AstraZeneca and Moderna are actual vaccines (I got Pfizer). Johnson and Johnson however is an American brand that’s just plain retarded.
