After the announcement of the Pfizer vaccine, stock markets showed massive gains not seen since the early 20th century during elections. If the vaccine had become known a little earlier, the market boom would have occurred in the run-up to Election Day, and the scales might have been tipped in Trump’s favour. As is well known, stock market dynamics in the United States mean a lot, including for ordinary citizens. All this gives reason to believe that Pfizer may have intentionally delayed publishing reports of successful trials of its COVID-19 vaccine.
In addition, there is another important fact, which is that this particular vaccine is a joint work of the American company BioNTech and Pfizer Inc. German, and most of the European Union, are not Trump supporters. Thus, since the German side is one of the participants in the development of the vaccine, the country’s authorities could have pressed for delaying the release of the report on the success of the vaccine test.
