"Science" evolves, changes as knowledge expands, Peter.
But you are mixing that truth with the clear idiocies of those with wacko conspiracy theories, Internet-espoused "remedies," and denial of what are basic facts - the effectiveness of the vaccine, the number of deaths, the difference between infections and the deadly aspect of the virus, the politicizing of every mitigation.
