There are options beyond covid vaccines and conspiracy. Classification of covid deaths is one, such as how many days ago did you have covid. Particularly in the US, financial incentives to classic deaths as covid deaths may come into play. Misdiagnosis and mismanagement also come to mind.
For instance, in Italy in the early days, covid cases, many elderly, were vacated from hospitals to nursing homes. Here they were put on midazolam and morphine to relax them. Problem is that midazolam suppresses the respiratory system, which is the last thing you want to do when someone, particularly elderly, has a respiratory disease.
