"Decades of experience with coronavirus vaccines in animals shows that the most successful of these products protect against infection for a period of weeks or months at most. Indefinite booster regimens or annual revaccinations are routine for animals that aren’t destined for immediate slaughter. None of these vaccines provides even the slightest prospect of eradicating any coronaviruses, or even of controlling them in any significant way." Hum, so the story that the WuDoom vax will work for ever is at best a lie.
