evidence: COVID-19 vaccines — like all vaccines and other medical products — come with side effects, including serious side effects in rare cases. The vaccines were rolled out to protect people from a novel virus that has killed millions of people globally and would likely have killed millions more without the arrival of the vaccines. There is a broad consensus from experts and governmental health agencies that the benefits of COVID-19 vaccination outweigh the risks. [...] "What we take away, is that the Covid-19 vaccination campaigns have been very effective in preventing severe disease," study co-author Anders Hviid, head of the department of epidemiology research at the Statens Serum Institut in Denmark, told us in an email. "The few serious side effects that we have observed in this and other studies have been rare." [...] "Hundreds of millions of people were used as lab rats and now the truth that WE ALL ALREADY KNEW can no longer be denied," said one popular post, referring to the vaccines as "experimental" and "UNTESTED." The post shared a screenshot of the headline of a New York Post article about the new study, which read, "COVID vaccines linked to slight increases in heart, brain, blood disorders: study."
