This article, about examining the dangers of the COVID-19 Omicron variant, is a reprint of a comment made by the user Dave Barton in response to the article published yesterday regarding the effectiveness of boosters. I thought what he wrote was too important to be hidden in a Disqus comment. It was slightly edited for readability and style purposes.Read More »Examining the COVID Omicron variant — is it actually less dangerous?
I have seen a few comments about the need for COVID-19 vaccine boosters before and after the appearance of the new Omicron variant. Of course, anti-vaxxers use this as a reason to deny the effectiveness of the vaccine. However, I’ve even seen pro-vaxxers misunderstand why boosters are needed.
Today, Pfizer announced that its preliminary studies showed that individuals who have received boosters produce about 25X more neutralizing antibodies against the Omicron variant than those who received the COVID-19 vaccine alone. This is awesome news with the caveat that this has not been peer-reviewed or published, it is just a report from Pfizer itself. In the hierarchy of vaccine research, it is pretty low until it is published in a medical journal.

There is a lot of information about these boosters out there, so I thought I would take a moment to try to provide some facts and clarity about what the recommendations are about these COVID-19 vaccine boosters. Also, this is related to a US FDA set of decisions and recommendations from the CDC, so this article is going to only apply to the USA. However, don’t be surprised if the EU and other regulatory agencies across the world do the same thing.Read More »COVID-19 vaccine boosters FAQs – what you should know
